Exhibit 99.1

BioTime CEO Michael West to Present at French-American Biotech Symposium, San Francisco, April 11-12, 2011

Update on ReCyte™ technology for resetting telomere length
and its application in cardiovascular disease

ALAMEDA, Calif.--(BUSINESS WIRE)--March 4, 2011--BioTime, Inc. (NYSE Amex:BTX) and its subsidiary ReCyte Therapeutics, Inc. announced today that BioTime CEO Dr. Michael West will present at the French-American Biotech Symposium on “New Therapeutic Approaches of Aging” in San Francisco, April 11-12, 2011. Dr. West will speak on “Resetting Telomere Length using Transcriptional Reprogramming and its Application in Age-Related Degenerative Disease” on Tuesday, April 12, during Session III: Innovative Approaches to Chronic Diseases Associated with Aging.

On March 16, 2010, BioTime announced in a peer-reviewed scientific publication that iPS cell reprogramming technologies could, under certain conditions, reverse the developmental aging of human cells. In other words, by genetically modifying aged cells from the human body, they could be reverted back to an embryonic state similar to that of embryonic stem cells, which are capable of developing into all other cell and tissue types. In addition, it was previously reported that these reprogramming technologies could reset the telomere clock of cellular aging. On April 12, Dr. West will be presenting new data validating this technology. In particular, evidence will be presented that the technique is capable not only of resetting telomere length, but also of restoring the proliferative lifespan of aged human cells. Dr. West will also describe the plans of BioTime’s subsidiary ReCyte Therapeutics, Inc. to commercialize its own proprietary iPS cell technology. The relative advantages of this novel technique over the classic, but potentially genetically unstable, iPS cell methods will be outlined, as will BioTime’s progress with reprogrammed young vascular progenitors for the treatment of age-related cardiovascular disease.

This is the fourth French-American Biotech Symposium co-organized by The Office for Science and Technology of the French Embassy in Washington, DC and Eurobiomed, a French biotech cluster dedicated to health sciences, in partnership with the Gladstone Institute for Virology and Immunology.

Dr. West's presentation will be available on BioTime's website at www.biotimeinc.com. For more information on ReCyte Therapeutics, please visit our website at www.recytecorp.com.
