Advanced Cell Technology's Shares to Trade Today on Over-the-Counter Bulletin Board.

WORCESTER, Mass. -- Advanced Cell Technology, Inc. (Advanced Cell, ACT) (OTCBB: ACTC) announced today that effective immediately the Company's shares will be traded on the Over-the-Counter Bulletin Board under its previous ticker symbol ACTC. The Company is now fully reporting and up-to-date with all of its filing requirements. The Company's stock had previously traded on the Pink Sheets.

"I am gratified that the Company was able to achieve another significant milestone for its shareholders," said William M. Caldwell IV, Advanced Cell's Chairman and CEO. "Trading on the OTCBB should allow for increased transparency and facilitate the trading of our stock with a broader group of investors. In the last 12 months, Advanced Cell has completed a dramatic turnaround, made even more impressive by the obstacles it has had to overcome. We were able to cure a default with our Indenture holders, working out an equitable settlement for all of our constituencies; we raised capital through a series of licensing agreements and a private placement, allowing us to continue development activities which we expect will culminate in an IND filing this year for our RPE program; and, we have been able to retain key members of our scientific and management team, despite the adversity we have faced. We strongly believe in the potential for our science, and look forward to aggressively developing our clinical programs in the coming months."
