Business Wire, Nov 20, 2008

ALAMEDA, Calif. -- BioTime, Inc. (OTCBB:BTIM) Chief Executive Officer Michael West, Ph.D. delivered the keynote presentation on Wednesday, November 19, at a meeting in Madison, Wisconsin commemorating the 10th anniversary of the publication describing the first derivation and culturing of human embryonic stem cells. Dr. West's presentation is titled "Opportunities and Challenges of Commercializing Stem Cell Research." The Wisconsin Academy, along with University of Wisconsin-Madison and the Wisconsin Alumni Research Foundation (WARF), hosted the two-day event titled "A Decade Celebrating Stem Cells: Changing the Face of Medicine Ten Years Later" to commemorate the publication of the first derivation of human embryonic stem cells and to examine future trends.

Dr. West's presentation included a historical overview of the biotechnology industry, a description of historical trends in the industry of commercializing stem cell technology, and a discussion of future opportunities for the field. Dr. West discussed BioTime's stem cell research program that is focused on opportunities for near-term revenues in the development and marketing of products derived from stem cells.

Dr. West announced the launch of ten new cell line products and presented data on their unique properties and potential utility in regenerative medicine. The molecular markers of these lines are consistent with varied types of human neural crest, mesodermal, and CNS progenitor cells that have promise for the treatment of numerous diseases such as cranial-facial, muscular, and neurological disorders. Information about these cell lines will be available online at www.embryome.com starting Monday, November 24, 2008, and the cells themselves are now available for purchase for research purposes only through the same website.

Lastly, Dr. West discussed federal policies relating to the industry of regenerative medicine. He announced an open letter to President-Elect Obama signed by 22 scientists and economists (including 19 Nobel laureates), urging the new Administration to make regenerative medicine, specifically, the cure of human disease, a national priority, similar in scope to the Kennedy Administration's commitment to land a man on the moon within that decade. The text of the letter to President-Elect Obama is available online at www.biotimeinc.com.
