 of common stock and dilutive common stock equivalents.  All common stock
 equivalents (stock options and warrants) have been excluded from earnings
 per share for the periods ended March 31, 1997 and 1996, as the effect of
 these common stock equivalents is antidilutive.

 The Company is a defendant in a wrongful termination lawsuit which arose
 when the Company determined to liquidate its European subsidiary. 
 Management, based in part on consultation with legal counsel, believes this
 suit is without substantial merit and should not result in a judgment which
 in the aggregate would have a material adverse effect on the Company s
 financial statements.
 
 A restructuring reserve was established when the Company liquidated its
 European subsidiary.  Management has elected to retain this accrual until
 all matters related to the liquidation have been settled.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)
 
 NOTE 7 --   PROPOSAL TO MERGE WITH ANOTHER BUSINESS.
 
       Due to the Company's limited revenues and declining cash resources,
 resulting from a reduced customer base for its proprietary in vitro safety
 testing products and the lack of endorsement of the Company's products by
 governmental agencies, the Company's board of directors has authorized
 management to explore and negotiate a merger of the Company with another
 business enterprise.  This strategy is intended to provide for survival of
 the Company and realization of shareholder value by a business combination
 with another entity offering the potential of adding revenues.  Any such
 transaction will be subject to approval of the Company's board of directors
 and is also anticipated to require approval by a majority of the Company's
 shareholders.  A transaction of this nature anticipates the acquisition of
 additional assets or business operations in exchange for a controlling
 interest in the Company via the issuance of additional equity securities. 
 Any such transaction is expected to involve substantial dilution to the
 equity interests of the Company's shareholders.
 
       On May 13, 1997, the Company entered into a letter of intent to merge
 with Miragen Inc. in a transaction expected to provide current Company
 shareholders with approximately 20% of the surviving corporation's common
 stock, subject to possible adjustments based on business developments prior
 to execution of a definitive agreement.  The proposed merger with Miragen
 Inc. followed termination, by mutual agreement, of negotiations relating to
 a previously announced Company proposal to merge with Shenyang
 International Inc.  The proposed merger with Miragen Inc. is subject, among
 other conditions, to completion of due diligence investigations, approval
 by the board of directors for each of the parties, preparation and
 execution of a definitive merger agreement, filing appropriate materials
 with the Securities and Exchange Commission and approval by the majority
 vote of InVitro shareholders.  Miragen Inc., based in Irvine, California,
 develops, manufactures and sells proprietary biological identification and
 testing products used in hospital and medical laboratories and for animal
 identification and forensic applications.  InVitro currently acts as a
 distributor for Guardian DNA child identification and safety products
 supplied by Miragen under a prior agreement executed in 1996.  Founded in
 1993, Miragen's revenues for its fiscal year ended March 31, 1997 were
 approximately $68,000 excluding Miragen sales of Guardian DNA products to
 InVitro.  Two of the Company's officers, directors and shareholders,
 Messrs. Irwin J. Gruverman and William M. Curtis, are also founders,
 officers, directors and shareholders of Miragen Inc.  Messrs. Gruverman and
 Curtis both abstained from participating in negotiations relating to the
 Company's letter of intent with Miragen Inc. and will abstain from voting
 on the proposed merger as members of the Company's Board of Directors.

                          INVITRO INTERNATIONAL
                 MANAGEMENT'S DISCUSSION AND ANALYSIS OF 
               FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
       The following discussion should be read in conjunction with the
 Consolidated Financial Statements and notes thereto appearing elsewhere in
 this Report.
 
 RESULTS OF OPERATIONS:
 
       REVENUES:   For the six months ended March 31, 1997 (the "1997
 Period") revenues were $423,000, an decrease of 13% from revenues of
 $485,000 in the six months ended March 31, 1996 (the "1996 Period").  The
 decrease was due to an overall decline in sales of the Company's safety
 testing products during the second quarter ended March 31, 1997.  Revenues
 for the quarter ended March 31, 1997 were $164,000, a decline of $96,000
 compared to revenues of $260,000 for the comparable quarter ended March 31,
 1996 in the prior fiscal year.  To date, the marketing of Guardian DNA
 child safety and identification products through distribution of sales
 materials in hospital gift packs to new mothers have not generated sales of
 consequence.
 
       The Company's management believes that sales of its IRRITECTION Assay
 System and CORROSITEX test kits to determine Packing Group classification
 of corrosive substances will either remain relatively stable or continue to
 decline.  Various efforts to obtain governmental agency endorsement for use
 of the Company's products have proven unsuccessful, as exemplified by the
 U.S. Department of Transportation ("DOT") recent endorsement of animal
 testing methods for use by its regional operations, notwithstanding a DOT
 regulatory exemption permitting use of CORROSITEX for packing group
 classification and the fact that CORROSITEX offers significantly lower
 costs and faster results than are available by animal testing methods. 
 Other marketing strategies employed by the Company have failed to increase
 commercial interest in the Company's safety testing products.
 
       To take advantage of its internal sales force and distribution
 capabilities, the Company entered into an exclusive distributorship
 agreement in March 1996 to market the Guardian-DNA child identification
 system to and through hospitals, birthing and other institutional obstetric
 markets.  During October 1996, the Company entered into an agreement
 providing for the distribution of Guardian DNA literature and discount
 coupons in hospital gift packs to approximately 300,000 new mothers per
 month commencing in January 1997.  The response to this program has been
 minimal, and the Company intends to discontinue this program.  The Company
 will reduce its staff during May 1997 to lower operating costs, and sales
 and marketing activities will be focused almost exclusively on efforts to
 sell and distribute Guardian DNA directly to one or more affiliated
 hospital chains.  Although preliminary indications for obtaining orders
 from two hospital chains appear promising, there can be no assurance that
 these efforts will be successful.
 
       COSTS OF GOODS SOLD:    Cost of revenues for the 1997 Period were
 $289,000, or approximately 68.3% of sales, compared to $333,000, or 68.7%
 of sales, for the 1996 Period, resulting in gross profit margins of 31.7%
 for the 1997 Period compared to 31.3% in the 1996 Period.  Due to fixed
 manufacturing costs, a portion of which are unabsorbed due to low revenues,
 gross margins for the Company's proprietary in vitro products and services
 are expected to remain at or near present levels until sales growth
 necessary to absorb a higher percentage of fixed costs is attained, as to
 which there can be no assurance.  Gross margins in future periods are
 expected to show improvement only if the Company's introduction of Guardian
 DNA products at a favorable price per unit proves successful, since the
 Company's cost of revenues for Guardian DNA is limited to the purchase of
 finished kits from a supplier and a limited amount of warehouse space to
 store Guardian DNA inventories.
 
 
                                    -8-
  
      SELLING, GENERAL AND ADMINISTRATIVE EXPENSES.   Selling, general and
 administrative expenses were $1,019,000 in the 1997 Period, an decrease of
 approximately $18,000 compared to $1,037,000 in selling, general and
 administrative expenses for the 1996 Period.  Reductions in staff and
 facilities expense during the 1997 Period were largely offset by increased
 marketing expenses associated with the introduction of Guardian DNA
 products.  Due to further reductions in staff and abandonment of the
 hospital gift pack marketing program, management expects that selling,
 general and administrative expense will be reduced in future periods.
 
       RESEARCH AND DEVELOPMENT.    Research and development expenses for
 the 1997 Period were $38,000, a $105,000 decrease from $143,000 in research
 and development expenses in the 1996 Period.  To conserve capital
 resources, the Company previously elected to outsource as much of its
 research and development requirements for the near term as is possible. 
 Consistent with this policy, the decline in research and development
 expenses is primarily attributable to reductions in personnel and decreased
 expenditures for research materials and supplies.
 
       OTHER INCOME.    Interest income was $22,000 in the 1997 Period, a
 decline of $17,000 compared to the 1996 Period.  The decrease in interest
 income was attributable to a reduction in average cash balances compared to
 the 1996 Period.
 
       NET LOSS.    The Company's net loss of $901,000 during the 1997
 Period declined by approximately $88,000, a 9% decrease compared to the
 $989,000 net loss for the 1996 Period.  The Company's management
 anticipates the Company will continue to incur losses, but at a lower rate
 based on cost reductions noted above, due to the Company's declining
 revenues and fixed expenses for manufacturing overhead and selling, general
 and administrative expenses.  Losses are expected to continue until such
 time as sales increase to a level necessary to absorb fixed costs.  No
 assurances can be given as to whether or when sales increases may be
 achieved.
 
       The Company's operating management currently believes that a
 profitable level of operations cannot be attained unless the Company
 acquires or is merged with another business that can generate additional
 revenues.   See Note 7 of the Notes to Consolidated Financial Statements
 included earlier in this Report.  There can be no assurance of future
 growth in revenues, or that the Company will achieve revenue increases in
 an amount necessary to attain profitable operations or that the Company
 will successfully complete a merger with another business entity.
 
 LIQUIDITY AND CAPITAL RESOURCES:
 
       At March 31, 1997, the Company's cash resources totalled $383,000 and
 its working capital was $829,000.  Included in the Company's working
 capital are $503,000 in inventories, much of which represents Guardian DNA
 products that are dependent upon the successful introduction of this
 product line for the Company to realize the value of these inventories. 
 During the six months ended March 31, 1997, the Company's cash and cash
 equivalents securities decreased by $826,000, due primarily to cash
 outflows used by operating activities of $1,044,000, partially offset by
 the collection of $225,000 in net proceeds from the sale of common stock.
 
       The Company's principal capital requirements include working capital
 to finance sales and marketing activities and general and administrative
 expenses.  The Company has no significant pending commitments for capital
 expenditures or new product development, and capital equipment additions
 are not expected to be material in amount for the foreseeable future. 
 During the six months ended March 31, 1997, the Company's inventories
 increased by $137,000 primarily as the result of increases in quantities of
 Guardian DNA to support the market launch of that product line.
 
       Based on currently planned activities, management believes that its
 cash resources at March 31, 1997 are sufficient to fund the Company's
 operations at least through September 30, 1997.

                      PART II -- OTHER INFORMATION
 
 ITEM 5.   OTHER INFORMATION.
 
 ABANDONMENT OF PROPOSED MERGER WITH SHENYANG INTERNATIONAL
 
       On March 3, 1997, the Company announced it had signed a letter of
 intent to merge with Shenyang International Inc. in a transaction where the
 Company's shareholders would retain 20% of the combined entity's common
 stock.   Due to delays on the part of Shenyang International, that merger
 proposal was not presented to the Company's board of directors for
 consideration and the proposed merger with Shenyang International has been
 abandoned by mutual consent of the parties.
 
 
 PROPOSAL TO MERGE WITH MIRAGEN INC.
 
       Due to the Company's limited revenues and declining cash resources,
 resulting from a reduced customer base for its proprietary in vitro safety
 testing products and the lack of endorsement of the Company's products by
 governmental agencies, the Company's board of directors has authorized
 management to explore and negotiate a merger of the Company with another
 business enterprise.  This strategy is intended to provide for survival of
 the Company and realization of shareholder value by a business combination
 with another entity offering the potential of adding revenues.  Any such
 transaction will be subject to approval of the Company's board of directors
 and is also anticipated to require approval by a majority of the Company's
 shareholders.  A transaction of this nature anticipates the acquisition of
 additional assets or business operations in exchange for a controlling
 interest in the Company via the issuance of additional equity securities. 
 Any such transaction is expected to involve substantial dilution to the
 equity interests of the Company's shareholders.
 
       On May 13, 1997, the Company entered into a letter of intent to merge
 with Miragen Inc. in a transaction expected to provide current Company
 shareholders with approximately 20% of the surviving corporation's common
 stock, subject to possible adjustments based on business developments prior
 to execution of a definitive agreement.  The proposed merger with Miragen
 Inc. is subject, among other conditions, to completion of due diligence
 investigations, approval by the board of directors for each of the parties,
 preparation and execution of a definitive merger agreement, filing
 appropriate materials with the Securities and Exchange Commission and
 approval by the majority vote of InVitro shareholders.
 
       Miragen Inc., based in Irvine, California, develops, manufactures and
 sells proprietary biological identification and testing products used in
 hospital and medical laboratories and for animal identification and
 forensic applications.  InVitro currently acts as a distributor for
 Guardian DNA child identification and safety products supplied by Miragen
 under a prior agreement executed in 1996.  Founded in 1993, Miragen's
 revenues for its fiscal year ended March 31, 1997 were approximately
 $68,000 excluding Miragen's sales of Guardian DNA products to InVitro.
 
       Two of the Company's officers, directors and shareholders, Messrs.
 Irwin J. Gruverman and William M. Curtis, are also founders, officers,
 directors and shareholders of Miragen Inc.  Messrs. Gruverman and Curtis
 both abstained from participating in negotiations relating to the Company's
 letter of intent with Miragen Inc. and will abstain from voting on the
 proposed merger as members of the Company's Board of Directors.
 
 
 LOSS OF NASDAQ SMALL-CAP MARKET LISTING
 
       The Company was recently advised that its common stock will be
 delisted from The Nasdaq SmallCap Market at the close of business on May
 14, 1997 for failure to satisfy minimum standards for continued listing.
 The Company expects that its common stock will remain actively traded in
 the over-the-counter market and quoted under the symbol "INVI" on the NASD
 Electronic Bulletin Board.
 
                                   -10-
  
      A consequence of delisting from The Nasdaq SmallCap Market is that
 the Company's common stock may be deemed subject to rules of the Securities
 and Exchange Commission applicable to "penny stocks".  The Securities
 Enforcement and Penny Stock Reform Act of 1990 requires additional
 disclosure relating to the market for "penny stocks", as defined.  A "penny
 stock" is generally defined as any equity security that has a market price
 of less than $5.00 per share, subject to certain exceptions.  Such
 exceptions include any equity security listed on Nasdaq and any equity
 security issued by an issuer that has (i) net tangible assets of at least
 $2,000,000, if such issuer has been in continuous operation for three (3)
 years; (ii) net tangible assets of at least $5,000,000 if such issuer has
 been in continuous operation for less than three (3) years; or (iii)
 average annual revenue of at least $6,000,000 if such issuer has been in
 continuous operation for less than three years.  Unless an exception is
 available, the regulations require the delivery, prior to any transaction
 through a broker-dealer involving a penny stock, of a disclosure schedule
 explaining the penny stock market and associated risks.
  
      In addition, so long as the Company's securities are not quoted on
 Nasdaq or the Company does not have $2,000,000 in net tangible assets,
 trading in the Common Stock would be covered by Rule 15c2-6 promulgated
 under the Securities Exchange Act of 1934 for non-Nasdaq and non-exchange
 listed securities.  Under that rule, broker/dealers who recommend such
 securities to persons other than established customers and accredited
 investors must make a special written suitability determination for the
 purchaser and receive each purchaser's written agreement to a transaction
 prior to sale.  Securities also are exempt from this rule if the market
 price is at least $5.00 per share.
