     Proxy Statement for the 2002 Annual Meeting of Stockholders
                    To Be Held on August 29, 2002

     This Proxy Statement is furnished in connection with the solicitation
of proxies by the Board of Directors of Diacrin, Inc. (the "Company") for
use at the Annual Meeting of Stockholders to be held on August 29, 2002
(the "Annual Meeting") and at any adjournment of that meeting.  All proxies
will be voted in accordance with the stockholders' instructions, and if no
choice is specified, the proxies will be voted in favor of the matters set forth
in the accompanying Notice of Meeting.  Any proxy may be revoked by a
stockholder at any time before its exercise by delivery of a written revocation
or a subsequently dated proxy to the Secretary of the Company or by voting
in person at the Annual Meeting.

     The Company's Annual Report for the year ended December 31,
2001 was mailed to stockholders, along with these proxy materials, on or
about July 26, 2002.

     A copy of the Company's Annual Report on Form 10-K for the
year ended December 31, 2001, as filed with the Securities and Exchange
Commission, except for exhibits, will be furnished without charge to any
stockholder upon written request of Investor Relations, Diacrin, Inc.,
Building 96, 13th Street, Charlestown Navy Yard, Charlestown,
Massachusetts 02129. Exhibits will be provided upon written request
upon payment of an appropriate processing fee.

Securities and Votes Required

     At the close of business on July 5, 2002, the record date for the
determination of stockholders entitled to vote at the Annual Meeting, there
were outstanding and entitled to vote 17,937,204 shares of common stock,
$0.01 par value per share (the "Common Stock")  (constituting all of the
outstanding voting stock of the Company).  Each share of Common Stock
entitles the holder to one vote.

     Under the Company's By-laws, the holders of a majority of the
shares of Common Stock issued, outstanding and entitled to vote at the
Annual Meeting shall constitute a quorum for the transaction of business at
the Annual Meeting.  Shares of Common Stock present in person or
represented by proxy (including shares which abstain or do not vote with
respect to one or more of the matters presented for stockholder approval)
will be counted for purposes of determining whether a quorum is present at
the Annual Meeting.

     If a quorum is present, the affirmative vote of the holders of a
plurality of the shares of Common Stock present (either in person or by
proxy) and entitled to vote is required for the election of directors.  If a
quorum is present, the affirmative vote of the holders of a majority of the
shares of Common Stock present (either in person or by proxy) and entitled
to vote is required to ratify the selection of PricewaterhouseCoopers LLP as
the Company's independent auditors for the current year.  For purposes of
tabulating the vote, abstentions will be treated as shares that are present and
entitled to vote.  Accordingly, an abstention will have the same effect as a
vote against the matter.  In addition, if a broker or nominee holding stock in
"street name" indicates on the proxy that it does not have discretionary
authority to vote as to a particular matter, those shares will not be considered
as present and entitled to vote with respect to that particular matter.
Accordingly, a "broker non-vote" on a matter will have no effect on the
outcome of the voting on such matter.



Principal Stockholders

     The  following  table  sets  forth  the  beneficial  ownership  of the
Company's Common Stock as of June 15, 2002 by:

     - each person who is known to beneficially own more than 5% of the
       Company's Common Stock;

     - each of the Company's directors;

     - each of the Company's executive officers; and

     - all of the Company's executive officers and directors as a group.

     Unless otherwise noted, each person or group has sole voting and
investment power of the shares listed.  The inclusion of any shares listed
below as beneficially  owned does not constitute an admission of beneficial
ownership of those shares.

     The "Options" column reflects shares of the Company's Common
Stock subject to options which are exercisable within 60 days after June 15,
2002. The shares of the Company's Common Stock which are subject to
options are deemed to be outstanding  for the purpose of computing the
percentage of ownership of the  person  holding  such  options,  but are not
deemed to be  outstanding  for computing the percentage of ownership of any
other person. As of June 15, 2002, there were 17,937,204 shares of the
Company's Common Stock outstanding.

Meetings of Board of Directors and Committees

     During 2001, the Board of Directors held seven meetings.  Each
director attended at least 75% of the meetings of the Board and of the
committees on which he then served.

     The Company has a Compensation Committee composed entirely of
directors who are not employees of the Company.  The Committee provides
recommendations to the Board regarding compensation programs of the
Company, administers the Company's stock option plans and is authorized to
grant stock options under such plans to officers and directors of the
Company.  In addition, this Committee approves the compensation paid to
the President and Chief Executive Officer and other executive officers of the
Company.  The Compensation Committee met once during 2001.  The
current members of the Compensation Committee are Messrs. Littlechild and
Termeer and Dr. Papadopoulos.  See "Report of the Compensation
Committee" below.

     The Company has an Audit Committee which provides the
opportunity for direct contact between the Company's independent auditors
and the Board, reviews the effectiveness of the auditors during the annual
audit, monitors the Company's internal accounting control policies and
procedures, oversees financial reporting to stockholders, oversees the ethical
behavior of management, and considers and recommends the selection of the
Company's independent auditors.  The Audit  Committee met three times
during 2001.  The current members of the Audit Committee are Drs.
Horovitz and Papadopoulos and Mr. Ruch. See "Report of the Audit
Committee" below.

     The Company does not have a Nominating Committee or a
committee serving similar functions.  Nominations are made by and through
the full Board of Directors.

Director Compensation

     Dr. Horovitz receives $2,000 plus expenses per board meeting
attended plus an additional $4,000 annually for consulting work performed
on behalf of the Company.  No other directors receive any cash
compensation for services on the Board of Directors.

     On June 11, 2001, all non-employee directors were granted an
option to purchase 6,000 shares of common stock under our 1997 Stock
Option Plan at an exercise price of $2.00 per share.  The options may be

Employment Agreements

     The Company has entered into a letter agreement with Dr. Fraser
dated February 6, 1990, providing for an annual salary plus bonus as
determined by the Board of Directors.  The Company has agreed with Dr.
Fraser to continue to pay his then current salary for a period of six months if
it terminates his employment without cause.  Dr. Fraser has also agreed not
to compete with the Company for one year following termination of his
employment.  At the Company's election, this non-competition provision can
be extended for an additional two-year period upon the payment of additional
consideration.

Section 16(a) Beneficial Ownership Reporting Compliance

     Section 16(a) of the  Securities  Exchange Act of 1934, as
amended (the "Exchange  Act"),  requires our directors, executive  officers
and persons  who own more than ten percent of a  registered class  of our
equity  securities  to file  with the  Securities  and Exchange  Commission
initial  reports of  ownership  and  reports of changes in ownership of
common stock and other equity securities.  Officers, directors and greater
than ten percent beneficial owners are required to furnish us with copies of
all Section 16(a) forms that they file.

     Based solely on our review of the copies of such reports received or
written representations that no other reports were required, we believe that,
except as follows, during the fiscal year ended December 31, 2001, our
officers, directors and ten-percent stockholders complied with all Section
16(a) filing requirements applicable to such individuals. A Form 5, Annual
Statement of Changes in Beneficial Ownership, for Mr. Littlechild reporting
a stock option grant made during 2001 was inadvertently filed late.

Report of the Compensation Committee

     The Company's executive compensation program is administered by
the Compensation Committee (the "Committee"), which is composed of three
directors who are neither employees nor officers of the Company.  The
Committee reviews and approves the salaries and incentive compensation of
the Chief Executive Officer and the other executive officers of the Company.
The objectives of the Company's executive compensation program
are as follows:

-	provide an incentive for the achievement of strategic goals and
        objectives of the  Company;
-	support the pay-for-performance concept by tying executive
        compensation to the Committee's subjective determination of the
        quality of performance for the preceding fiscal year;
-	attract and retain key executives essential to the long-term
        success of the Company; and
-	align the executive officers' interests with the long-term interests
        of the stockholders.

     The Company's executive compensation program consists of three
principal elements: base salary, an annual management cash bonus and
incentive stock options. The Company does not believe that section 162(m)
of the Internal Revenue Code of 1986, as amended, which disallows a tax
deduction for certain compensation in excess of $1 million, will generally
have an effect on the Company.



     Given that the Company is in the process of developing its initial
products, the Committee does not believe that the use of profit levels as a
measure of the Company's achievements or as a basis for compensation
decisions is appropriate.  However, the Committee considers the ability to
control losses without compromising the progress of the Company's product
development programs.

     The Chief Executive Officer submits for the Committee's
consideration at the end of the fiscal year the amount of proposed
compensation (following fiscal year base salary, current fiscal year cash
bonus and stock option awards) for himself and for the Company's other
executive officers.  The factors considered by the Chief Executive Officer in
making his recommendations to the Committee are the Board of Directors'
prior evaluation of the Company's success in meeting its strategic objectives
during the most recent fiscal year and the Chief Executive Officer's
subjective evaluation of each executive officer's individual performance.
The Committee acts upon the recommendations made with respect to the
executive officers after weighing the Board of Directors' evaluation of the
Company's overall achievements for the year, the Chief Executive Officer's
discussion of each executive officer's individual performance for the year and
each executive officer's current level of compensation.  The Committee
members, based upon their active professional involvement with other
companies within the Company's industry, are also able to assess whether
proposed compensation levels are in keeping with industry norms.

     The Committee applies the same criteria in evaluating the Chief
Executive Officer's cash compensation as that applied to the other executive
officers of the Company.  The base salary for fiscal 2001 of the President
and Chief Executive Officer of the Company was increased by $5,000 to
$275,000.  On January 14, 2002, the Compensation Committee granted Dr.
Fraser an option to purchase 65,000 shares of Common Stock at a per share
exercise price of $2.08 for his performance during the 2001 fiscal year.  The
option was granted at an exercise price equal to the fair market value of the
Company's Common Stock on the date of grant and vests in four annual
installments commencing one year following the date of grant as long as Dr.
Fraser remains employed by the Company.  In awarding this option to Dr.
Fraser, the Committee subjectively considered the compensation criteria
discussed above as well as its interests in providing incentives for long-term
performance, promoting retention of employees and further aligning the
interests of the Chief Executive Officer with that of the stockholders.

     During 2001, the Committee adopted a retention plan. The plan
provides for a cash payment to each participant if they continue to be
employed by the company at certain dates. Participants in the plan include
the Named Officers.

     PROPOSAL TWO: RATIFICATION OF SELECTION OF INDEPENDENT AUDITORS

     The Audit Committee of the Board of Directors of the Company
annually considers and recommends to the Board of Directors the selection
of the Company's independent auditors. Effective July 8, 2002, the Audit
Committee dismissed Arthur Andersen LLP as its independent auditors and
engaged PricewaterhouseCoopers LLP as its independent auditors for the
fiscal year ending December 31, 2002. This engagement is being submitted
to the stockholders for ratification. Although stockholder approval of the
Audit Committee of the Board of Directors' selection of
PricewaterhouseCoopers LLP is not required by law, the Board of Directors
believes that it is advisable to give the stockholders an opportunity to ratify
this selection. If this proposal is not approved at the Annual Meeting, the
Board of Directors will reconsider the selection of PricewaterhouseCoopers
LLP.

     Arthur Andersen LLP's audit reports on the Company's financial
statements for each of the two most recent fiscal years ended December 31,
2000 and 2001 did not contain an adverse opinion or a disclaimer of opinion
nor were they qualified or modified as to any uncertainty, audit scope or
accounting principal.

     In connection with the audits for the periods ended December 31,
2000 and 2001, and the subsequent interim period through the dismissal of
Arthur Andersen LLP, there were no disagreements with Arthur Andersen
LLP on any matter of accounting principles and practices, financial
statement disclosure or auditing scope or procedure, which, if not resolved to
the satisfaction of Arthur Andersen LLP, would have caused them to refer to
such disagreement in connection with their report. In addition, during such
period there were no "reportable events" as defined in Item 304(a)(1)(v) of
Regulation S-K.



     During the periods ended December 31, 2000 and 2001 and the
subsequent interim period through the engagement of
PricewaterhouseCoopers LLP, neither the Company nor anyone on its behalf
consulted PricewaterhouseCoopers LLP with respect to the application of
accounting principles to a specified transaction, either completed or
proposed, or the type of audit opinion that might be rendered on the
Company's financial statements nor has PricewaterhouseCoopers LLP
provided a written report or oral advice that was an important factor
considered by the Company in reaching a decision as to any accounting,
auditing or financial reporting issue.

     Representatives of PricewaterhouseCoopers LLP are expected to be
present at the Annual Meeting to be available to respond to appropriate
questions from stockholders and to make a statement if they desire to do so.
Representatives of Arthur Andersen LLP are not expected to be present at
the Annual Meeting. The Board of Directors recommends a vote in favor
of this proposal.

Report of the Audit Committee

     The Audit Committee of the Company's Board of Directors is
composed of three members and acts under a written charter first adopted
and approved in June 2000.

     The Audit Committee is comprised of Joshua Ruch, Stelios
Papadopoulos and Zola P. Horovitz. The three members of the Audit
Committee are each independent directors, as defined by the rules of the
Nasdaq Stock Market.

     At an Audit Committee meeting held on March 11, 2002 (the
"March 2002 meeting"), the Audit Committee reviewed the Company's
audited financial statements for the fiscal year ended December 31, 2001 and
discussed these financial statements with the Company's management.  At
the March 2002 meeting, the Audit Committee also reviewed and discussed
the audited financial statements and the matters required by Statement on
Auditing Standards 61 (Communication with Audit Committees) with Arthur
Andersen LLP, the Company's independent auditors for the fiscal year ended
December 31, 2001.

     At the March 2002 meeting, the Company's independent auditors
also provided the Audit Committee with the written disclosures and the letter
required by Independence Standards Board Standard No. 1 (Independence
Discussions with Audit Committees).  The Audit Committee discussed with
the independent auditors the matters disclosed in this letter and their
independence from the Company.  The Audit Committee also considered
whether the independent auditors' provision of the other, non-audit related
services to the Company that are referred to below under the heading
"Independent Auditors Fees and Other Matters" is compatible with
maintaining such auditors' independence.

     Based on its discussions with management and the independent
auditors, and its review of the representations and information provided by
management and the independent auditors, the Audit Committee at the
March 2002 meeting recommended to the Company's Board of Directors
that the audited financial statements be included in the Company's Annual
Report on Form 10-K for the year ended December 31, 2001.

reviews of the financial statements included in each of the Company's
Quarterly Reports on Form 10-Q during the fiscal year ended December 31,
2001.

Financial Information Systems Design and Implementation Fees

     Arthur Andersen LLP did not bill the Company for any professional

2001 in connection with financial information systems design or
implementation, the operation of the Company's information system or the
management of its local area network.

All Other Fees

     Arthur Andersen LLP billed the Company an aggregate of $12,500
in fees for other services rendered to the Company for the fiscal year ended
December 31, 2001.

                            OTHER MATTERS

     The Board of Directors does not know of any other matters which
may come before the Annual Meeting.  However, if any other matters are
properly presented to the Annual Meeting, it is the intention of the persons
named in the accompanying proxy to vote, or otherwise act, in accordance
with their judgment on such matters.

     All costs of solicitation of proxies will be borne by the Company.  In
addition to solicitations by mail, the Company's directors, officers and
employees, without additional remuneration, may solicit proxies by
telephone, or otherwise.  Brokers, custodians and fiduciaries will be
requested to forward proxy soliciting material to the owners of stock held in
their names, and, as required by law, the Company will reimburse them for
their reasonable out-of-pocket expenses in this regard.



Proposals for the 2003 Annual Meeting

     In order to be included in proxy materials for the 2003 Annual
Meeting of Stockholders, pursuant to Rule 14(a)-8 under the Exchange Act,
stockholders' proposed resolutions must be received by the Company at its
offices, Building 96, 13th Street, Charlestown Navy Yard, Charlestown,
Massachusetts 02129 on or before February 25, 2003.  The Company
suggests that proponents submit their proposals by certified mail, return
receipt requested, addressed to the Secretary of the Company.

     If a stockholder of the Company wishes to present a proposal before
the 2003 Annual Meeting of Stockholders (other than a proposal to be
included in the proxy statement pursuant to Rule 14(a)-8 as described in the
prior paragraph), pursuant to Rule 14(a)-4 under the Exchange Act, such
stockholder must give written notice to the Secretary of the Company at the
address noted above.  The Secretary must receive such notice at least 45
days prior to the anniversary of the mailing of this year's proxy materials,
which would be June 11, 2003.  If a stockholder fails to provide timely
notice of a proposal to be presented at the 2003 Annual Meeting of
Stockholders, the proxies designated by the Board of Directors of the
Company will have discretionary authority to vote on any such proposal.

Householding of Annual Meeting Materials

     Some banks, brokers and other nominee record holders may be
participating in the practice of "householding" proxy statements and annual
reports. This means that only one copy of our proxy statement or annual
report may have been sent to multiple stockholders in your household. We
will promptly deliver a separate copy of either document to you if you call or
write us at the following address or phone number: Diacrin, Inc., Building
96, 13th Street, Charlestown Navy Yard, Charlestown, Massachusetts
02129, Attention: Investor Relations, (617) 242-9100. If you would like to
receive separate copies of the annual report and proxy statement in the
future, or if you are receiving multiple copies and would like to receive only
one copy for your household, you should contact your bank, broker, or other
nominee record holder, or you may contact us at the above address and
phone number.


                                      By Order of the Board of Directors,
