Item 2.      Acquisition or Disposition of Assets.

On December 31, 2002 (the "Effective Time"), Celgene Corporation, a Delaware
corporation (the "Registrant"), consummated the acquisition of Anthrogenesis
Corp., a New Jersey corporation ("Anthrogenesis"). Anthrogenesis is an
early-stage biotherapeutics company delivering stem cell therapies produced from
renewable human placental sources/materials. The merger was consummated pursuant
to the Purchase Option Agreement and Plan of Merger, dated April 26, 2002, as
amended (the "Plan of Merger"), by and among the Registrant, Celgene Acquisition
Corp., a New Jersey corporation and a wholly-owned subsidiary of the Registrant
(the "Merger Sub"), and Anthrogenesis. Pursuant to the Plan of Merger, the
Merger Sub merged with and into Anthrogenesis, and Anthrogenesis continued as
the surviving corporation. At the Effective Time, Anthrogenesis became a
wholly-owned subsidiary of the Registrant.

Under the Plan of Merger, each share of Anthrogenesis common stock that was
outstanding immediately prior to the Effective Time of the merger was converted
into the right to receive 0.4545 of a share of the Registrant's common stock,
par value $.01 per share ("Common Stock"). The Registrant issued approximately
1.45 million shares of Common Stock to former Anthrogenesis shareholders in the
merger. In addition, approximately 1.3 million shares of the Registrant's Common
Stock were reserved for issuance upon exercise of outstanding Anthrogenesis
stock options and warrants that were assumed by the Registrant pursuant to the
Plan of Merger. These options and warrants were converted into options and
warrants to acquire shares of the Registrant's Common Stock on the basis of the
0.4545 exchange ratio in the merger.

Prior to the completion of the merger, the shares of the Registrant's Common
Stock that were issued and reserved for issuance in connection with the merger
were registered under the Securities Act of 1933 pursuant to a registration
statement on Form S-4 (File No. 333-101196) (the "Registration Statement"). The
Registration Statement was declared effective on November 26, 2002. The merger
is described in greater detail in the Registration Statement.

The Registrant's acquisition of Anthrogenesis was structured as a tax-free
reorganization under Section 368(a) of the Internal Revenue Code and was
accounted for using the purchase method of accounting for business combinations.

The foregoing description of the Plan of Merger does not purport to be complete
and is qualified in its entirety by reference to the full text of the Plan of
Merger, including the amendment dated September 6, 2002 which, among other
things, sets forth the exchange ratio, which are incorporated herein by
reference as Exhibits 2.1 and 2.2 to this Current Report on Form 8-K.

                   CELGENE COMPLETES ANTHROGENESIS ACQUISITION

        Celgene Leverages Commercial and Scientific Franchises to Develop
                 Transforming Placental Stem Cell Therapeutics


WARREN, NJ - (January 2, 2003) - Celgene Corporation (NASDAQ: CELG) announced
today the completion of its merger with Anthrogenesis Corporation, a privately
held biotherapeutics company pioneering the recovery of stem cells from human
placental tissue. Anthrogenesis has developed proprietary methods for
collecting, processing and storing placental stem cells and has organized three
main business units: stem cell transplantation, private stem cell banking and
the development of biomaterials for organ and tissue repair. Anthrogenesis will
operate as a wholly owned subsidiary of Celgene.

Anthrogenesis' proprietary technology procures large quantities of
high-potential stem cells from human placental tissue. These stem cells can be
used in bone marrow transplants to treat cancer, particularly hematological
cancers such as multiple myeloma and leukemia, in conjunction with chemotherapy
and radiation therapy. From a single placental source, Anthrogenesis can produce
multiple stem cell transplant units that exceed current adult dosing standards
for use in bone marrow transplants. From the same placental source,
Anthrogenesis recovers large quantities of very early-stage stem cells that
appear to have many of the characteristics attributed to embryonic stem cells.
Unlike the embryo, the placenta is a non-controversial source of stem cells.
Through its commercial franchise, Celgene will provide stem cell transplant
units to oncologists treating hematological cancers.

"Placental stem cells have the potential to transform the way physicians treat
serious diseases and the way novel therapies are developed," said John W.
Jackson, Chairman and Chief Executive Officer of Celgene Corporation. "This
strategic acquisition combines the proprietary technology of Anthrogenesis with
our commercial and development expertise to realize the substantial commercial
and therapeutic potential of placental stem cells."

Summary of Financial Terms
Under the terms of the agreement first announced in November, Celgene will
acquire all Anthrogenesis outstanding shares in a tax-free, stock-for-stock
merger that will be accounted for by the purchase method of accounting. Based on
an exchange ratio of .4545, Celgene will issue 1.45 million common shares.
Celgene will also issue 1.3 million options and warrants at the same exchange
ratio. The acquisition was completed on December 31, 2002 and will be accounted
for in the fourth quarter of 2002. Celgene expects the merger with Anthrogenesis
to be $0.05 to $0.10 dilutive to earnings in 2003, $0.05 to $0.10 accretive in
2004, and to have a positive impact on earnings thereafter.
