ANN ARBOR, Mich., Apr 8, 2008 (PrimeNewswire via COMTEX News Network) -- Aastrom Biosciences, Inc. (Nasdaq:ASTM), a leading regenerative medicine company, today announced that the Company's Special Meeting of Shareholders was adjourned and will reconvene on Tuesday, May 6, 2008 at 9:00am (EDT), at Aastrom's office, 24 Frank Lloyd Wright Drive, Lobby K, Ann Arbor, MI 48105. The purpose of the meeting was to consider a proposal to authorize the Company's Board of Directors to effect a reverse stock split. Aastrom reported that a quorum was present at the meeting and that the reverse stock split proposal received FOR votes in excess of 58% of the outstanding shares; however, the Company had not yet achieved the two-thirds (66-2/3%) vote required by the Company's charter for the proposal. Aastrom's Board of Directors considers this proposal, which is intended to assure the preservation of the Company's Nasdaq Capital Market listing, critical to the future of the Company. Therefore, the Board determined it was essential to provide additional time to continue to obtain greater shareholder turnout and achieve the necessary two-thirds vote for this proposal.

"More than ever, we are excited about Aastrom's business prospects. The reverse split proposal is vital to the future of the Company and merits shareholder support. Being delisted from the Nasdaq Capital Market would have serious consequences and a reverse stock split represents an important strategic option to avoid delisting," said Nelson M. Sims, Chairman of the Board of Directors of Aastrom. "The Board urges all shareholders to vote FOR this proposal so that together we continue to build on the accomplishments of our clinical development programs, advance the interests of our Company, and enhance the potential of significant long-term value for our shareholders."

Aastrom reported that its proposal has received a FOR recommendation from Institutional Shareholder Services, Inc. (ISS), a wholly-owned subsidiary of RiskMetrics Group, Inc. ISS issued its recommendation report on March 10, 2008, recognizing that "the reverse split is necessary to maintain compliance with Nasdaq Capital Market listing standards. Therefore, we believe that this proposal warrants shareholder approval."

"We plan to take advantage of the meeting adjournment period to reach out to our shareholders to reemphasize the importance of this vote," stated George Dunbar, President and Chief Executive Officer of Aastrom.
