BioTime, Inc. (NYSE Amex:BTIM) announced that the Company’s CEO Dr. Michael West will present data today relating to 12 new cell lines, differentiation kits, and cell culture media at the GTCbio 4th Advances in Stem Cell Discovery and Development Conference in San Francisco, California. Dr. West’s presentation titled: “Fate Space Screening of Clonal Human ES-derived Embryonic Progenitor Cell Lines” will include a discussion of the Company’s proprietary bank of more than 140 diverse human cell types made from human embryonic stem cells, the company’s screening technology for discovering means of manufacturing human cell types, and the potential use of these cells for diverse new therapeutics and drug discovery.

During his lecture, Dr. West will describe the 12 new lines: B28, EN23, Z3, EN5, RASMO19, EN27, T42, SK47, SM2, SK46, T44, and SK44 that will be launched beginning November 1, 2010. He also will disclose new data on the cell lines: SK17 that have the potential to differentiate into cells that express renin and smooth muscle cell-related genes characteristic of the juxtaglomerular apparatus of the kidney, Z2 that when differentiated using a proprietary protocol expresses relatively high levels of the bone growth factor genes BMP2 and BMP7 (also known as osteogenic protein-1 (OP-1), and J16 that expresses preadipocyte markers of interest to researchers in cosmetic dermatology and type II diabetes.

In addition, Dr. West will disclose for the first time the Company’s PureStem TM technology, with which the Company plans to expand its product offerings in calendar year 2011. The PureStem TM technology utilizes the expression of exogenous transcriptional regulators to control the differentiation of human embryonic stem cells and induced plutipotent stem cells, and may potentially provide many new human cell types needed in regenerative medicine. BioTime is seeking patent protection for the PureStem TM technology.

Additional information about these new products will be found at www.embryome.com beginning on November 1, 2010. Dr. West’s presentation is available on BioTime’s website at www.biotimeinc.com.

The annual GTCbio Stem Cell Research & Therapeutics Conference provides information regarding cutting-edge developments in all areas of stem cell research including the biology, medicine, applications, regulations, and business of stem cells. This year’s conference will address recent developments in pre-clinical and clinical trials of stem cell therapy, regenerative medicine and tissue engineering, cancer stem cells, stem cell reprogramming, FDA and NIH policies regarding funding for stem cell research, and private funding from the pharmaceutical industry.
