                                    PROSPECTUS SUMMARY

     The following  summary  is  qualified  in  its  entirety  by  the detailed
information  and  financial  statements appearing elsewhere or incorporated  by
reference in this Prospectus.



                                        THE COMPANY

     THERMOGENESIS CORP. (the  "Company"), formerly known as Insta Cool Inc. of
North  America,  was  incorporated  in  Delaware  on  September  26,  1986  and
subsequently  merged  with   Refrigeration   Systems   International,  Inc.,  a
California corporation.  In January of 1995, the Company  changed  its  name to
THERMOGENESIS  CORP.  to  better  reflect  the  thermodynamic  segment  of  the
biotechnology  industry  that  it  hopes  to service through development of new
products.  The Company designs and sells products and devices which utilize its
proprietary  thermodynamic  technology  for  the   processing   of   biological
substances  including  the  cryopreservation, thawing, and harvesting of  blood
components, and to a lesser extent  for  the  preservation  of perishable foods
(THERMOGENESIS  Proprietary  Technology).  Historically, the Company's  primary
revenues have been from sales  of  blood  plasma  freezers  to hospitals, blood
banks  and  blood  transfusion  centers  for  rapid  freezing of blood  plasma.
Currently,  the  Company is manufacturing several categories  of  thermodynamic
devices which are being sold to the blood plasma industry under permission from
the Food and Drug  Administration  ("FDA").  Other  potential  applications and
markets for the Company's THERMOGENESIS Proprietary Technology includes medical
and  pharmaceutical  applications,  and  industrial  applications.  During  the
fiscal years 1988 through 1995, the Company has focused its efforts on research
and  development and on refining product design and application.   The  Company
has also  continuously sought new applications for its products and technology,
including the  design  of  a  device  used for the intraoperative harvesting of
autologous fibrinogen rich cryoprecipitate  for  use  as  a hemostatic agent or
tissue sealant in certain surgical and medical procedures.   See  "The  Company
and Recent Events - Current Products and Development Efforts".


     Pursuant to the terms of the private placement, the Company is registering
the  Common  Stock  offered  by  the Selling Stockholders.  The Company is also
registering Common Stock to be issued upon the exercise of outstanding Warrants
issued  as part of the Units in the  private  placement  pursuant  to  contract
terms.  To  the  extent  required  under  the  federal  securities  laws,  this
Prospectus  may  be  used  for resale of Common Stock upon the  exercise of the
Warrants by the holders of such Warrants.


                                       THE OFFERING

Common Stock Outstanding Before the Offering                       24,765,434

Nasdaq Symbol                                                             KOOL


                                       RISK FACTORS

     An  investment  in  the  Common Stock described herein entails a number of
very significant risks.  Because  of these risks, funds should only be invested
by persons able to bear the risk of  and  withstand  the  loss  of their entire
investment.   Prospective  investors should also consider the following  before
making an investment decision.


     LACK OF PROFITABILITY.   Except  for  net  income  of $11,246 for the year
ended  June  30,  1994  on net sales of $2,678,192, the Company  has  not  been
profitable since inception.   For the year ended June 30, 1995, the Company had
a net loss of $88,296 on net sales  of $3,311,880 and an accumulated deficit at
June 30, 1995, of $5,814,394.   See "Annual  Report  on  Form 10-KSB".  For the
six months ended December 31, 1995, the Company had a net  loss  of $102,339 on
sales of $1,980,119.

     DEPENDENCE  UPON  NEW  PRODUCTS.  Historically, substantially all  of  the
Company's revenue has been from  the  sales of product related to the freezing,
thawing and storing of blood plasma.  Because  the  Company  expects  the blood
plasma market to have limited growth, the future success of the Company will be
dependent  upon  new  applications of its technology, including application  of
products in the biotechnology  market.   The  Company intends to concentrate on
developing  (1)  an  autologous fibrinogen processing  device  with  disposable
containers; (2) a long-term sample storage and retrieval system with disposable
containers; and (3) a  stem  cell  control  rate  freezer  ("CRF"), storage and
retrieval  system  with  disposable  containers.  See "The Company  and  Recent
Events  -  Current Products and Development  Efforts."   Although  these  three
products use  technology  related to the freezing, thawing and storage of blood
plasma, development of these products represents a departure from the Company's
current core business.  Further,  although  the  Company  has  had  encouraging
discussions   with   experts  in  areas  of  application  for  these  products,
development of each product  is  in  its pre-application or initial development
phase and the Company has no contracts  for  sales of these three products.  No
assurance  can  be  given  that  each  of these products  can  be  successfully
developed, and if developed, that a market will develop for them.

     POSSIBLE  ADDITIONAL FINANCING.  Based  on  current  sales  and  projected
development costs  for  products currently in development, the Company believes
that it will have sufficient  working  capital  for its operations for the 1997
fiscal year.  In the event actual sales of the Company's  products  do not meet
the  Company's  expectations in any given period, or development and production
costs  increase significantly,  the  Company  may  need  to  secure  additional
financing  to  complete and fully implement its business objectives.  There can
be no assurance  that  the  Company  will not need additional financing, and if
available,  that  it  will  be obtained on  terms  favorable  to  the  Company.
Furthermore, delays in receipt  of any required governmental approvals prior to
marketing products in development,  or  requirements  for  additional  clinical
testing  prior  to  approval,  may  result  in decreased revenues and increased
development costs.  See "Risk Factors -- Government  Regulation Associated with
Products".

     GOVERNMENT  REGULATION  ASSOCIATED WITH PRODUCTS.   The  majority  of  the
Company's products require permission  to  market in the United States from the
United  States  Food  and  Drug  Administration ("FDA"),  which  may  limit  or
circumscribe applications or U.S.  markets for which the Company's products may
be  sold.   Further,  if  the Company cannot  establish  that  its  product  is
substantially equivalent, or  superior,  in  safety or efficacy to a previously
approved  product,  delays  may  result  in final approval  from  the  FDA  for
marketing its products.  No assurance can  be  given  that  FDA  permission  to
market  in  the  United States will be obtained.   The Company's products might
also be required to  meet  certain  other criteria or receive certain approvals
from other foreign governments for marketing  and  sales.  See "The Company and
Recent Events - Current Products and Development Efforts".

     RELIANCE  ON  PATENTS  AND  OTHER  PROPRIETARY INFORMATION.   The  Company
believes  that  patent  protection  is important  for  products  and  potential
segments of its current and proposed  business.   The Company currently holds 4
patents, and has patents pending for an additional 3 products which the Company
markets or intends to market.  See "Annual Report on  Form  10-KSB".  There can
be no assurance, however, as to the breadth or degree of protection afforded to
the  Company or the competitive advantage derived by the Company  from  current
patents  and  future  patents,  if any.  Although the Company believes that its
patents and the Company's existing  and  proposed products do not infringe upon
patents of other parties, it is possible that  the  Company's  existing  patent
rights  may  be  challenged  and  found invalid or found to violate proprietary
rights of others.  In the event any of the Company's products are challenged as
infringing, the Company would be required  to modify the design of its product,
obtain a license or litigate the issue.  There is no assurance that the Company
would be able to finance costly patent litigation,  or that it would be able to
obtain licenses or modify its products in a timely manner.  Failure to defend a
patent  infringement  action  or  to  obtain  a  license or  implementation  of
modifications would have a material adverse effect  on  the Company's continued
operations.

     TRADE  SECRETS.   The  Company  also relies in part on trade  secrets  and
proprietary know-how, and it employs various methods to protect its technology,
such  as  use  of  confidentiality  agreements  with  employees,  vendors,  and
customers.  However, such methods may  not afford complete protection and there
can be no assurance that others will not  obtain  the  Company's  know-how,  or
independently develop it.

     DEPENDENCE   ON   KEY   PERSONNEL  AND  OBTAINING  ADDITIONAL  ENGINEERING
PERSONNEL.  The Company is dependent upon the experience and services of Philip
H. Coelho, President and Chief  Executive Officer, and Charles de B. Griffiths,
Director of International Sales.  The loss of Mr. Coelho or Mr. Griffiths would
adversely affect the Company's operations.   The  Company  has obtained key man
life  insurance  covering  Mr.  Coelho  in  the  amount of $1,000,000  as  some
protection  against  this  risk.   Furthermore, to implement  its  new  product
development, the Company will have to recruit and retain additional experienced
engineers.  There is no assurance that  the  Company  will  be able to find and
retain  engineers  required  to  meet  its self-imposed deadlines  for  product
development.  See "The Company and Recent Events - Employees".

     DEPENDENCE ON FOREIGN SALES.  A large  percentage  of  the Company's sales
are made to foreign countries.  For the year ended June 30, 1995, foreign sales
represented 55% of the Company's total sales for the year.  The  Company is not
aware of any current material risks associated with foreign sales.   Sales  are
made  in  U.S.  currency  and,  therefore,  currency fluctuations do not affect
operations.  See "Annual Report on Form 10-KSB".

     PRODUCT LIABILITY AND UNINSURED RISKS.   The  Company  maintains a general
liability policy which includes domestic and foreign product liability coverage
of  $1,000,000  per  occurrence  and  $2,000,000  per  year  in  the aggregate.
Nevertheless, a partial or completely uninsured claim against the Company could
have  a  material  adverse  effect  on  the  Company's financial condition  and
operations.

     POSSIBLE LOSS OF NASDAQ SMALLCAP MARKET ELIGIBILITY.   While the Company's
Common Stock is included on the Nasdaq SmallCap Market, its continued inclusion
will  depend on the Company's ability to meet certain eligibility  requirements
established  for The Nasdaq Stock Market, including maintaining a minimum of $2
million in assets.   Loss  of  Nasdaq  eligibility  could result if the Company
sustains  substantial  material  operating  losses  affecting  its  net  worth.
Although  the  Company  could seek listing on another market,  any  failure  to
maintain listing on the Nasdaq  could have an adverse effect on trading and the
value of the Company's Common Stock.

     NEGATIVE  IMPACT  ON TRADING VALUE  OF  COMMON  STOCK.   The  Company  has
currently  more  than  24,000,000  shares  outstanding,  including  the  shares
registered hereby, almost all of which are registered and trading.  Because the
trading  market  for  the  Company's  common  stock  is  affected  by  numerous
circumstances and events, the  Company can make no prediction on the effect the
registration of the shares of common  stock  hereby  will  have on that market.
The  number  of  shares being registered by the Company hereby  could  have  an
adverse effect on  the  trading  value  of  its  Common  Stock in general.  See
"Description of Securities - Registration Obligation".

     LACK  OF  CASH  DIVIDENDS.   To date, the Company has not  paid  any  cash
dividends on its Common Stock and does not expect to declare or pay any cash or
other dividends on its Common Stock in the foreseeable future.

                               THE COMPANY AND RECENT EVENTS

     The  Company,  formerly  known  as  Insta  Cool Inc. of North America, was
incorporated  in Delaware on September 26, 1986 and  subsequently  merged  with
Refrigeration  Systems  International,  Inc.,  a  California  corporation.   In
January of 1995,  the Company changed its name to THERMOGENESIS CORP. to better
reflect the thermodynamic  segment  of the biotechnology industry that it hopes
to service through development of new  products.  The Company designs and sells
products and devices which utilize its proprietary thermodynamic technology for
the  processing  of  biological  substances   including  the  cryopreservation,
thawing, and harvesting of blood components, and  to  a  lesser  extent for the
preservation   of  perishable  foods  (THERMOGENESIS  Proprietary  Technology).
Historically, the  Company's  primary  revenues  have  been from sales of blood
plasma  freezers  to hospitals, blood banks and blood transfusion  centers  for
rapid  freezing of blood  plasma.   Currently,  the  Company  is  manufacturing
several  categories  of thermodynamic devices which are being sold to the blood
plasma industry under  FDA  permission  to  market  in the United States. Other
potential applications and markets for the Company's  THERMOGENESIS Proprietary
Technology  include  medical  and pharmaceutical applications,  and  industrial
applications.  During the fiscal  years  1988  through  1995,  the  Company has
focused its efforts on research and development and on refining product  design
and application.  The Company has also continuously sought new applications for
its  products  and  technology,  including  the design of a device used for the
intraoperative harvesting of autologous fibrinogen rich cryoprecipitate for use
as  a  hemostatic  agent  or  tissue sealant in certain  surgical  and  medical
procedures.   See  "The  Company and  Recent  Events  -  Current  Products  and
Development Efforts".

HISTORICAL

     Tools used by biotechnology  researchers  to process biological substances
and to accomplish manipulation of such substances  to  obtain  desired  results
vary and include microscopic laser scalpels, chemical formulations, sterile and
disposable  containers,  as  well  as  devices that control temperatures of the
processes.

     The Company's initial strategy focused  product development on small niche
blood  processing  markets  where  new products could  more  quickly  establish
credibility  for  the  Company's  proprietary  thermodynamic  technology.   The
Company believed that by concentrating  its  products to serve the blood plasma
industry,  many customers, such as the Red Cross  or  other  blood  transfusion
societies of  various  countries,  would  validate the Company's technology for
rapid freezing of biological substances, more specifically blood plasma.  Early
products were designed and distributed to blood  processing markets in a manner
that  would permit the Company to attain high market  share  and  receive  more
rapid FDA 510K permission to market.  See "Annual Report on Form 10-KSB".

     From 1988 to 1992 the Company's products were designed to transfer heat by
causing  heat  transfer  liquids  to  indirectly contact biological substances,
primarily  blood plasma, contained within  plastic  sealed  containers.   Early
product designs used liquids containing chloro-flouro-carbons ("CFC") which the
Company phased  out  in the fall of 1992.  Thereafter, the Company developed an
alternative heat transfer method which automatically interposed a thin flexible
membrane between the heat  transfer  liquid  and  biological  substances  which
process allowed for use of non-CFC based heat transfer liquids.

     Principal  products  initially  developed  by  the Company and marketed to
hospitals, blood banks, and blood transfusion centers consisted of freezers and
thawers for blood plasma.  The Company continued to design  and develop various
freezer  models  and  thawers  for  different applications, and these  products
remain the core product component of  the  Company's  business.   To expand its
market  and  product  use,  the  Company changed the focus of its research  and
development to the design of new products  that  would  be applied to different
applications within the blood industry, including surgical,  pharmaceutical and
medical  procedures  that utilize freezing and thawing technology  as  part  of
standard procedures.  See "The Company and Recent Events - Current Products and
Development Efforts".

     Over the past seven  years,  the  Company  has  developed and received FDA
permission to market several of its thermodynamic processors  of  blood tissues
and  have  three  new products awaiting FDA approval.  The several FDA-approved
blood processing devices  have a significant share of their small niche markets
and  generate  the  majority  of  the  Company's  annual  revenues  which  were
approximately $3,300,000 during  the 1995 fiscal year.  For instance, of the 51
American  Red  Cross Blood Centers,  48  utilize  the  Company's  blood  plasma
freezer.  These  products  include  the  Company's blood plasma freezers, blood
thawers, and portable blood plasma freezers, and blood collection and transport
containers.  See Annual Report on Form 10-KSB.

     Having established a presence in markets where the need to freeze and thaw
blood tissues precisely and rapidly was critical,  the  Company  began to focus
its technology and tissue and development efforts towards harvesting fibrinogen
rich  cryoprecipitate  from  blood  for  use  as a hemostatic agent and  tissue
adhesive for medical and surgical use.  Medical  literature currently documents
important  practical  applications  for  fibrinogen  rich   cryoprecipitate  in
thirteen   distinct   areas,  including  plastic  surgery,  thoracic   surgery,
cardiovascular surgery,  orthopaedic  surgery,  and  opthamologic surgery.  The
Company's  fibrinogen collecting device with its disposable  container  sources
the fibrinogen  rich cryoprecipitate from a patient's own blood ("autologous"),
and is unique in  that  aspect  when  compared to current sources of fibrinogen
which generally rely on homologous single donations or pooled plasma.

RECENT FINANCING

     In December 1995, the Company completed  a  private  placement  raising  a
total  of  $2,200,000,  before  direct  expenses of $242,000 and other indirect
related expenses, for net proceeds of $1,901,000,  which  funds  are being used
for general corporate purposes that include, but are not limited to, payment of
existing  accounts payable and short-term debt, testing of products,  continued
research and  development,  production  costs  and  inventory,  advertising and
promotional materials, working capital, and increased payroll due  to  addition
of personnel.

     Assuming  the exercise of all Warrants issued as part of the Units in  the
private placement,  and  the exercise of the placement agent warrant to acquire
an additional 8.8 Units at  $30,000  per  Unit,  the  Company  would receive an
additional  $2,079,000,  which would be used to support general operations  and
research and development.   The  Company does not, however, anticipate that the
Warrants will be exercised prior to  expiration  on July 31, 1996, based on the
current trading price of $1.1875 on March 1, 1996.  See "Use of Proceeds".  The
Company will not receive any money from the sale of Common Stock offered by the
Selling Stockholders in this Offering.  See "Summary of the Offering"; "Selling
Stockholders".

     As a condition of the private placement of Units,  each  investor  in  the
private placement was required to enter into an agreement not to sell, directly
or  indirectly, the Common Stock included in the Units for a period of 180 days
from  the  effective date of the registration statement registering such Common
Stock without  the  prior  written  approval  of  the placement agent, Paradise
Valley Securities, Inc. (the "Investor Lock-Up").  In giving or withholding its
approval, the placement agent will consider the effect that any such sale prior
to  expiration  of  the Investor Lock-Up will have on  the  maintenance  of  an
orderly market for the  Company's Common Stock.  See "Description of Securities
- - Registration Obligation".  As part of the private placement of the Units, the
Company granted purchasers  of  the  Units a limited price protection provision
for the warrants issued as part of the  Units  to  mitigate   the effect of any
potential   market decline in the trading price of the Company's  Common  Stock
should the Company  delay  in registering the Common Stock.  Under the terms of
the provision, the exercise  price of the warrants would be automatically reset
at $1.00 per share in the event  a  registration statement was not filed within
three  months  following  the  close of the  private  placement.   The  Company
complied with the registration filing  requirement  and the repricing provision
is of no further effect.  All warrants issued as part  of the Units will expire
on July 31, 1996, unless exercised by the holders thereof prior to that date.

CURRENT PRODUCTS AND DEVELOPMENT EFFORTS

     The  Company's  core  business continues to focus on plasma  freezers  and
thawers which have already received  FDA  permission  to  market  in the United
States.  However, since the Company anticipates that the plasma freezer  market
will  flatten  when  market  penetration  is  complete  (with  the exception of
replacement products), it has begun to focus on the following new  products and
market opportunities.  See "Annual Report on Form 10-KSB".

     LONG-TERM  BLOOD  SAMPLE  STORAGE  AND  RETRIEVAL  SYSTEM  WITH DISPOSABLE
CONTAINER.   The  Company  has  built  a  prototype  long-term storage freezer,
computer inventory system and blood sample container (the  "Blood  Archive  and
Retrieval System") for possible use by the Japanese Red Cross for storing blood
samples for a five year period for all blood donations that occur in Japan each
year.   The  five-year  blood  sample  storage program has been mandated by the
Japanese government in an effort to comply  with  new product liability laws in
Japan.   It is estimated that 6,600,000 blood donations  occur  annually.   The
Company has  shipped the prototype Blood Archive and Retrieval System to Daido-
Hoxan, the Company's  Japanese  distributor,  in  November  1995  for tests and
performance  review.   The  Company believes that the Japanese government  will
approve a budget that will include purchases of the Blood Archive and Retrieval
System.  The Company, its distributor  Daido-Hoxan,  and the Japanese Red Cross
are currently evaluating the equipment and proposed program.  No  assurance can
be given that the Company's Blood Archive and Retrieval System will  ultimately
be  purchased  by  or  through  the  Japanese Government.  See "Risk Factors  -
Dependence on New Markets; Government Regulations Associated with Products".

     AUTOLOGOUS FIBRINOGEN PROCESSING  SYSTEM  WITH  DISPOSABLE CONTAINER.  The
Company  has completed a prototype of a system for harvesting  fibrinogen  rich
cryoprecipitate  from  a patient's own blood plasma for use as a tissue sealant
and hemostatic agent during  surgery (the "Autologous Fibrinogen Device").  The
Autologous Fibrinogen Device features a  transportable thermodynamic device and
sterile disposable containers  within  which  each  unit  of  blood  plasma  is
processed to obtain the fibrinogen rich cryoprecipitate.

     The  FDA  declined  to approve the use of the Autologous Fibrinogen Device
for all the surgical uses  of fibrinogen as sought by the Company and, instead,
agreed to constructively review  a 510K application for a few narrow uses, such
as Factor VIII deficiency (when blood  is deficient in the Factor VIII clotting
protein causing hemophilia) and fibrinogenemia  (when blood is deficient in the
Fibrinogen clotting protein).  Further clinical data would need to be collected
and  submitted in order to have the FDA permit expanded  claims  for  efficacy.
See "Risk  Factors  --  Government  Regulations Associated with Products".  The
restriction to these few narrow uses  would  significantly reduce initial sales
in the United States and force the Company to rely on foreign marketing.

     The Company has identified three significant  opportunities  to  bring the
Autologous  Fibrinogen  Device to market in the near future, while encompassing
all the potential surgical uses in Japan, Canada and Europe where fibrinogen is
already licensed, and one  major use in the United States where the Company may
have significant assistance  in  presenting  clinical data to support the claim
for autologous fibrinogen as a tissue adhesive.

1)         The  Company  secured an agreement in  principal  with  Haemonetics,
Japan, a major medical device company, which contemplates that Haemonetics will
manufacture the disposable  container and the applicators and pay the Company a
10% royalty on sales of those  items, in addition to purchases and distribution
of  the   Autologous Fibrinogen Device  to  be  manufactured  by  the  Company.
Haemonetics  would  market  the  Autologous  Fibrinogen  Device in Japan, where
fibrinogen  from  pooled  plasma  is  already a licensed product.   Further,  a
Ministry of Health and Welfare reimbursement schedule has already been approved
for autologous fibrinogen by the Japanese  government, even though no practical
supply of autologous fibrinogen exists today  in  Japan.   The Company believes
that the Japanese are uncomfortable with the only currently available supply of
fibrinogen in Japan which is sourced from pooled plasma donated by non-Japanese
donors.   Based  on  this  perception, the Company has focused development  and
introduction of this product  for  the  Japanese  market, while continuing with
efforts toward clinical data collection for additional  FDA  approval  for  the
United States Market.

2)         The   Company   has   reached   an   agreement   in  principle  with
Organogenesis,   a   Massachusetts-based   company   which   has  developed   a
biologically-alive skin replacement, Graftskin (trademark) produced  from cells
derived  from  infant  foreskin  and bovine collagen.  The Company was informed
that in clinical trials a 61% success rate was achieved in the complete closure
of  ulcerated wounds (diabetic), a  disease  which  afflicts  over  10  million
Americans.  In acknowledgment of the potential benefit this product might offer
to patients  with  ulcerated wounds, the FDA has chosen Graftskin for expedited
review.  The Company believes that bonding the Graftskin to the wound site with
autologous fibrinogen rich cryoprecipitate may increase the success rate of the
engraftment and is collaborating  with  Organogenesis in the design of clinical
tests  to  determine  whether the autologous  fibrinogen  rich  cryoprecipitate
sealant assists the engraftment.   If  successful,  this  test  data  would  be
submitted  to  the  FDA by the Company in support of a claim for the autologous
fibrinogen rich cryoprecipitate as a skin graft adhesive.  The Company believes
that this submission  could  be  reviewed  by  the  FDA at the same time as the
expedited review of the skin replacement product.  FDA permission to market the
Company's Autologous tissue sealant for use with Graftskin  could  open markets
to  over  200  specialized  wound  care centers, 3,000 surgi-centers and  3,500
hospitals with surgery wards in the  United  States.  Tests using the Company's
autologous  fibrinogen  device  are,  however,  in   preliminary   stages   and
conclusions   about   any   improved   engraftment   efficacy   are  premature.
Furthermore, there is no assurance that the FDA will review the data related to
the   Company's   device   contemporaneously   with   the  submissions  by  the
Massachusetts company.  See "Risk Factors - Government  Regulations  Associated
with the Products".

3)         The  Company  has  obtained agreement from Gail Rock, MD, Ph.D.,  to
organize  and  supervise  all  necessary   laboratory  and  clinical  tests  to
demonstrate  the  safety  and efficacy of the Company's  Autologous  Fibrinogen
Device for the Canadian Ministry  of  Health.   Canada  has licensed the use of
fibrinogen sourced from pooled plasma.

     Potential  additional  revenues  may  be  generated  from  the  Autologous
Fibrinogen  Device  by virtue of the Company's proprietary disposable  bag  set
designed for processing  the  patient's  plasma.   Each  use  of the Autologous
Fibrinogen Device will require use of a  proprietary sterile bag  set  that the
Company  currently  proposes to sell, thereby potentially creating a continuing
stream of revenues that  will  rise  with  the  cumulative number of autologous
fibrinogen devices operating, and the number of procedures  executed  with each
device.  The Company expects to license the manufacture and sale of the sterile
bags (containers) in both Japan and Europe in return for a 10% royalty  on  net
sales from such licenses.

     The  Autologous Fibrinogen Device is still in its pre-production phase and
is subject  to FDA permission to market in the United States.  No assurance can
be given that the FDA will grant permission to market the Autologous Fibrinogen
Device, or that  a  market  within  the United States will develop if approved.
See  "Risk Factors -- Government Regulations  Associated  with  the  Products".
Initially,  the  Company  intends  to  concentrate  on  foreign  markets  where
fibrinogen,  sourced from pooled plasma, is currently used to market the device
pending further applications for approval by the FDA.

     STEM CELL  CRF  STORAGE  AND  RETRIEVAL  SYSTEM WITH DISPOSABLE CONTAINER.
Placental stem cells have been identified by Dr. Pablo Rubinstein as a superior
alternative replacement to bone marrow for the  reconstitution  of  the  immune
system.   Dr.  Rubinstein  is  director  and  chief scientist of the F.H. Allen
Laboratory of Immunologenetics, Lindsey F. Kimball  Research  Institute  of the
New  York Blood Center.  Dr. Rubinstein directed a National Institute of Health
funded  research  program  which  demonstrated  the  effectiveness  of stem and
progenitor  cells  sourced from placental blood in accomplishing reconstitution
of the immune system  in  patients  unrelated to the donor source.  For optimum
therapeutic benefit, it is necessary  to  harvest  and  inventory  thousands of
cryopreserved  placental  stem cell donations, all of which must be genetically
typed.  In conjunction with  Dr.  Pablo Rubinstein's research over the past few
years, the Company developed a sterile  bag set for collecting, processing, and
freezing  the  stem cells sourced from placental  blood,  and  is  designing  a
sophisticated liquid  nitrogen  storage  system  which provides controlled rate
freezing ("CRF") of the stem cells and which robotically  archives  up to 2,500
donations  (the  "Stem  Cell  Storage  and  Retrieval  System")  for  use in an
international  blood banking network.  A laboratory prototype of the Stem  Cell
Storage and Retrieval  System  is  in  its  initial  phase  of development.  No
assurance  can be given that the Company will be able to develop  a  Stem  Cell
Storage and  Retrieval  System  and if developed, that a market for such system
will develop.  See "Risk Factors  -   Dependence  on  New  Markets;  Government
Regulations Associated with the Products".  The Stem Cell Storage and Retrieval
System also features a disposable clip designed to protect the stem cell bag at
below freezing temperatures and assists the recording of temperatures  that may
provide  revenues  to  the  Company  in  addition to revenues from sales of the
system.

     For a more complete discussion of the  Company  and its business and other
properties,  refer  to  the Company's Annual Report on Form  10-KSB,  which  is
incorporated herein by reference.


EMPLOYEES

     At fiscal year ended  June  30, 1995, the Company employed thirty-two (32)
regular full time employees.  In order  to  complete  research  and  design, to
build, market and service the new products in development, the Company hired an
additional eight (8) engineers, six (6) production personnel, a sales  manager,
and   six   (6)  additional  customer  support,  marketing  and  administrative
employees.  At  March  1,  1996,  the Company employed fifty-one (51) full time
employees.  The Company considers current  staffing  levels  adequate  at  this
time,  but  may  need  to add additional personnel to meet shortened production
times or to handle increases  in  business.  Similarly, any downturn in product
markets  or  sales  might  result in decreases  in  the  number  of  full  time
employees.


                                                     - 3 -





                                  SUMMARY OF THE OFFERING

     The Company is registering  4,400,000  shares of Common Stock on behalf of
the Selling Stockholders, and offering 1,210,000  shares  of  Common Stock upon
the  exercise  of  outstanding  Warrants.   The Common Stock and Warrants  were
issued in connection with a December 1995 private  placement  by the Company of
88 Units at $25,000 per Unit.  Each Unit consisted of fifty thousand  shares of
Common  Stock  and  a  Warrant  to  purchase an additional twelve thousand five
hundred (12,500) shares of Common Stock  at  $1.50 per share.  The Company also
granted the placement agent Warrants to purchase 8.8 Units at $30,000 per Unit,
each Unit having the same terms as the Units offered  in the private placement,
including the July 31, 1996 expiration of the Warrants  to be issued as part of
those Units.  See "The Company and Recent Events - Recent Financing".

     The Company will receive no proceeds from the sale of the 4,400,000 shares
of  Common  Stock  that may be offered and sold from time to  time  or  by  the
Selling Shareholders.

                                      USE OF PROCEEDS

     Assuming Warrants  to  purchase all of the 1,210,000 shares are exercised,
the  Company  expects  to  receive  $1,815,000  before  deducting  expenses  of
approximately $38,018 associated  with  this  Offering.   In  addition,  if the
placement agent Warrants to acquire the additional 8.8 Units are exercised, the
Company  will  also  receive  $264,000.  The Company intends to use any amounts
received from the exercise of these  Warrants  for  general corporate purposes.
As  of March 1, 1996, the average high and low price of  one  share  of  Common
Stock  was  $1.1875.   In  light  of  the current market price for one share of
Common Stock, and the exercise price of  the  Warrants,  it is unlikely at this
time that a holder of a Warrant would exercise the Warrant.

     The Company will not receive any proceeds upon the sale of Common Stock by
the Selling Stockholders.

                                   SELLING STOCKHOLDERS

     The following table identifies the Selling Stockholders,  as  of  March 5,
1996,  and  indicates  (i)  the  nature  of any material relationship that such
Selling Stockholders have had with the Company  for  the past three years, (ii)
the  number of shares of Common Stock held by the Selling  Stockholders,  (iii)
the amount  to  be  offered for the Selling Stockholders' account, and (iv) the
number of shares and  percentage  of  outstanding  shares of Common Stock to be
owned by the Selling Stockholders after the sale of the Common Stock offered by
the Selling Stockholders pursuant to this Offering.   The  Selling Stockholders
are not obligated to sell their Common Stock offered in this Prospectus and may
choose not to sell any of their shares or only a part of their shares.

     The  shares  of  Common Stock offered by the Selling Stockholders  may  be
offered for sale from time  to  time at market prices prevailing at the time of
sale or at negotiated prices, and without payment of any underwriting discounts
or  commissions except for usual and  customary  selling  commissions  paid  to
brokers or dealers.  The Company will not receive any proceeds from the sale of
the Common Stock by the Selling Stockholders.

     Under the Exchange Act, any person engaged in a distribution of the shares
of  Common   Stock   of   the  Company  offered  by  this  Prospectus  may  not
simultaneously engage in market  making  activities  with respect to the Common
Stock of the Company during the applicable "cooling off"  periods  prior to the
commencement  of  such  distribution.   In  addition, and without limiting  the
foregoing, each Selling Stockholder will be subject to applicable provisions of
the Exchange Act and the rules and regulations  thereunder  including,  without
limitation,  Rules  10b-6  and 10b-7, which provisions may limit the timing  of
purchases and sales of Common Stock by the Selling Stockholders.

     With regard to the shares  offered by the Selling Stockholders such shares
may be sold on the Nasdaq Stock Market  or in private transactions at prices to
be determined at the time of sale.  Such  shares may be offered through broker-
dealers, acting on the Selling Stockholders'  behalf,  who may offer the shares
at then current market prices.  Any sales may be by block  trade.   The Selling
Stockholders  and  any  brokers,  dealers  or  others who participate with  the
Selling Stockholders in the distribution of such  shares of Common Stock may be
deemed to be "underwriters" within the meaning of the  Securities  Act, and any
commissions  or  fees received by such persons and any profit on the resale  of
such shares purchased  by  such  persons  may  be  deemed  to  be  underwriting
commissions  or discounts under the Securities Act.  Sales may be made  by  all
Selling Stockholders  pursuant  to  the  Registration  Statement  of which this
Prospectus is a part.

                                 DESCRIPTION OF SECURITIES

     Pursuant to its  Amended  and  Restated  Certificate of Incorporation, the
Company  is  authorized to issue two classes of capital  stock,  designated  as
Common Stock and  Preferred  Stock.   The  authorized  Common Stock consists of
50,000,000 shares, $.001 par value, and the authorized Preferred Stock consists
of 2,000,000 shares, $.001 par value.

     As  of  March 5, 1996, the number of shares of  Common  Stock  outstanding
was 24,765,434.   There are no shares preferred stock outstanding.


COMMON STOCK

     Holders of  shares  of  the Common Stock have full voting rights, one vote
for each share held of record.   Subject  to  preferential rights of holders of
any series of Preferred Stock, holders of shares  of  Common Stock are entitled
to receive such dividends as may be declared by the Board  of  Directors out of
funds  legally  available therefor, and share pro rata in any distributions  to
stockholders upon  liquidation.   The holders of shares of Common Stock have no
conversion, preemptive or other subscription  rights.   All  of the outstanding
shares  of  Common  Stock are, and the shares offered hereby will  be,  validly
issued, fully paid and nonassessable.

PREFERRED STOCK

     The  Company's  Board  of  Directors  is  authorized  to  establish,  upon
authorization of a series  or  designation  of  Preferred  Stock,  the  rights,
preferences, privileges, and restrictions on such stock.  The Company currently
has  no  Preferred  Stock  outstanding,  and  the  Board  of  Directors has not
established any rights, preferences, privileges or restrictions on such stock.

OPTIONS

     As  of  March  5,  1996,  the  Company has outstanding options to  acquire
2,222,000 shares of Common Stock at exercise  prices ranging from $.82 to $1.50
per share.  Some of these options are subject to  vesting, and in general, have
a five year exercise period.

WARRANTS

     The Company issued warrants to purchase an aggregate  of  85,000 shares of
Common  Stock  in  connection  with  the  private  placement that concluded  in
February 1993.  Those  warrants may be exercised in  whole  or in part any time
before February 5, 1998, at an exercise price of $.60 per share.   The exercise
price  may  adjusted  from time to time in the event the Company subdivides  or
combines its outstanding  Common Stock.  The Company was obligated to register,
and  did  register the underlying  Common  Stock  of  the  Warrants  under  the
Securities Act, upon the one-time request of  holders of fifty percent (50%) of
those warrants.

     The Company  issued  Warrants to purchase an aggregate of 1,210,000 shares
of Common Stock in connection  with  the  private  placement  of Units that was
concluded in December 1996.  The Warrants may be exercised in whole  or in part
anytime before July 31, 1996.  The 1,210,000 shares are issuable at an exercise
price of $1.50 per share.  The exercise price may be adjusted from time to time
in  the event the Company subdivides or combines its outstanding Common  Stock.
The Company  is  contractually obligated to register the shares of Common Stock
underlying the Warrants  with  the Commission pursuant to the provisions of the
Securities Act.  As part of the  placement  agent's  compensation  in  the 1995
private  placement  of  Units, additional Warrants to purchase 8.8 Units at  an
exercise price of $30,000  per  Unit  were also issued, each Unit consisting of
fifty thousand (50,000) shares of Common  Stock  and   a  purchase  Warrant  to
purchase  an  additional twelve thousand five hundred (12,500) shares of Common
Stock, exercisable  at  $1.50  per share.  The Warrants to be issued as part of
the Units, and exercisable at $1.50  per  share,  have  been  included  in  the
1,210,000  Warrants.   The  Warrants  will  expire  on  July  31,  1996, unless
exercised  by  the  holders  thereof prior to that date.  See "The Company  and
Recent Events  - Recent Financing".

INVESTOR LOCK-UP

     Investors in the private placement of Units were required to enter into an
agreement not to sell, directly or indirectly, the Common Stock included in the
Units purchased for a period of  180  days  following  the  effective date of a
registration statement registering such shares for resale.  The placement agent
of  the  private  placement  o f Units may waive that condition and  allow  for
resale earlier under certain conditions.   The placement  agent has advised the
Company that in giving or withholding its approval, it will consider the effect
that any such sale will have on the maintenance  of  an  orderly market for the
Company's securities.   See "The Company and Recent Events - Recent Financing".

REGISTRATION OBLIGATION

     As  part  of  the  private placement of the Units, the Company  agreed  to
register the shares of Common  Stock  and shares of Common Stock underlying the
Warrants issued in the Units for resale under the Securities Act by filing with
the  Commission  a  registration  statement  on  Form  S-3  (the  "Registration
Obligation").  The Company has agreed  to  prepare  and  file such registration
statement  no later than ninety (90) days following the final  closing  of  the
private placement.  In the event the registration statement on Form S-3 was not
filed within  the  ninety  (90)  day period, the exercise price of the Warrants
issued as part of the Units would  have automatically been reduced, pursuant to
the terms of the Warrant, to $1.00 per  share.   The  Company complied with its
obligation to file the registration statement, and the  repricing  provision is
of  no further effect.  The Company paid all expenses necessary to prepare  and
file  the  registration statement.  See "The Company and Recent Events - Recent
Financing".

VOTING RIGHTS; DIVIDENDS

     The holders  of  Common  Stock will be entitled to one vote for each share
held of record on each matter submitted  to  a  vote of shareholders.  Further,
the holders of Common Stock will be entitled to receive  ratable dividends when
and  as  declared  by  the  Board  of  Directors  from funds legally  available
therefor.  In the event of a liquidation, dissolution  or  winding  up  of  the
Company,  the  holders of Common Stock will be entitled to share ratably in all
assets remaining  after  payment to holders of any series of preferred stock or
of any other senior securities  outstanding  at  such  time.  It is anticipated
that the Company will not be declaring dividends in the near future.

                          CERTIFICATE OF INCORPORATION AND BYLAWS

     The Company's Amended  and Restated Certificate of  Incorporation provides
for  the  indemnification  of directors and officers for certain  acts  to  the
fullest  extent permitted by  Delaware  Law.   Further,  the  Company's  bylaws
provide authority  for  the  Company  to  maintain a liability insurance policy
which insures directors or officers against  any  liability incurred by them in
their capacity as such.

     Insofar as indemnification for liabilities arising  under  the  Securities
Act  may  be  permitted  to directors, officers and controlling persons of  the
Company pursuant to the foregoing  provisions,  or  otherwise,  the Company has
been  advised  that  in  the opinion of the Commission such indemnification  is
against public policy as expressed  in  the  Securities  Act and is, therefore,
unenforceable.   In  the  event that a claim for indemnification  against  such
liabilities (other than the payment by the Company of expenses incurred or paid
by a director, officer or controlling  person  of the Company in the successful
defense  of  any  action,  suit or proceeding) is asserted  by  such  director,
officer  or  controlling  person   in  connection  with  the  securities  being
registered, the Company will, unless  in  the opinion of its counsel the matter
has been settled by controlling precedent,  submit  to  a  court of appropriate
jurisdiction the question whether such indemnification by it  is against public
policy  as expressed in the Act and will be governed by the final  adjudication
of such issue.

                                      TRANSFER AGENT

     The  Trust Company of New Jersey, Thirty-Five Journal Square, Jersey City,
New Jersey 07306 is the transfer agent for the Company's Common Stock.

Item 15.   Indemnification of Directors and Officers

     Section    145   of   the   Delaware  General  Corporation   Law   permits
indemnification of directors, officers  and  employees  of  corporations  under
certain  conditions  and subject to certain limitations.  Article Eighth of the
Company's Amended and  Restated Certificate of Incorporation contain provisions
for the indemnification  of  its  directors  and officers to the fullest extent
permitted by law.

     Under such law, the Company is empowered  to  indemnify any person who was
or is a party or is threatened to be made a party to any proceeding (other than
an action by or in the right of the Company to procure a judgment in its favor)
by reason of the fact that such person is or was an officer, director, employee
or other agent of the Company or its subsidiaries, against expenses, judgments,
fines,  settlements,  and  other  amounts actually and reasonably  incurred  in
connection with such proceeding, if  such  person  acted in good faith and in a
manner  such  person reasonably believed to be in the  best  interests  of  the
Company and, in  the  case of a criminal proceeding, has no reasonable cause to
believe the conduct of  such person was unlawful.  In addition, the Company may
indemnify, subject to certain  exceptions,  any person who was or is a party or
is  threatened  to  be made a party to any threatened,  pending,  or  completed
action by or in the right  of the Company to procure a judgment in its favor by
reason of the fact that such person is or was an officer, director, employee or
other agent of the Company or  its  subsidiaries, against expenses actually and
reasonably incurred by such person in connection with the defense or settlement
of such action if such person acted in  good  faith and in a manner such person
believed to be in the best interest of the Company  and  its shareholders.  The
Company  may  advance  expenses incurred in defending any proceeding  prior  to
final disposition upon receipt  of  an  undertaking  by the agent to repay that
amount it shall be determined that the agent is not entitled to indemnification
as authorized.

     In addition, although the Company does not have director's  and  officer's
insurance,  the  Company's  bylaws provide the Company authority to maintain  a
liability insurance policy which  insures  directors  or  officers  against any
liability incurred by them in their capacity as such, or arising out  of  their
status as such.  The Company intends to seek such insurance in the future.

Item 17. Undertakings

   The undersigned Company hereby undertakes:

   (1)  To  file, during any period in which offers or sales are being made,  a
post-effective amendment to this registration statement to include any material
information with  respect  to the plan of distribution not previously disclosed
in the registration statement or any material change to such information in the
registration statement;

   (2)  That, for the purpose of determining any liability under the Securities
Act,  each  such  post-effective   amendment  shall  be  deemed  to  be  a  new
registration statement relating to the  securities  offered  therein,  and  the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof;

   (3)  To  remove from registration by means of a post-effective amendment any
of the securities  being  registered  which remain unsold at the termination of
the offering.

   Insofar as indemnification for liabilities  arising under the Securities Act
of 1933 may be permitted to directors, officers  and controlling persons of the
Company  pursuant to the foregoing provisions, or otherwise,  the  Company  has
been advised  that  in  the  opinion  of the Commission such indemnification is
against public policy as expressed in the Act and is, therefore, unenforceable.
In the event that a claim for indemnification  against  such liabilities (other
than  the payment by the Company of expenses incurred or paid  by  a  director,
officer  or  controlling person of the Company in the successful defense of any
action,  suit  or   proceeding)  is  asserted  by  such  director,  officer  or
controlling person in  connection  with  the  securities  being registered, the
Company will, unless in the opinion of its counsel the matter  has been settled
by  controlling  precedent,  submit to a court of appropriate jurisdiction  the
question  whether such indemnification  by  it  is  against  public  policy  as
expressed in  the Securities Act and will be governed by the final adjudication
of such issue.

   For purposes  of  determining  any  liability  under the Securities Act, the
information  omitted  from  the  form  of  prospectus filed  as  part  of  this
registration statement in reliance upon Rule  430A  and  contained in a form of
prospectus filed by the registrant pursuant to Rule 424(b)(1)  or (4) or 497(h)
under  the  Securities  Act  shall  be  deemed  to be part of this registration
statement as of the time it was declared effective.

   For the purpose of determining any liability under  the Securities Act, each
post-effective amendment that contains a form of prospectus  shall be deemed to
be a new registration statement relating to the securities offered therein, and
the offering of such securities at that time shall be deemed to  be the initial
bona fide offering thereof.
