BioTime, Inc. (AMEX:BTIM) Chief Executive Officer Michael West, Ph.D. will give a presentation next week at the GTCbio 6th Annual Stem Cell Research & Therapeutics Conference, which will be held May 27-28, 2010 in Boston, Massachusetts. Dr. West will speak on “Fate Space Screening of Clonal Human ES-Derived Embryonic Progenitor Cell Lines for Chondrogenesis” in the meeting's first session, whose topic is “Differentiation of Stem Cells.” This annual conference provides leading-edge information on developments in all areas of stem cell research, including the biology, medicine, applications, regulations, and business of stem cells. This year's sessions will include discussions of the new federal funding opportunities that are arising as alternative sources of human embryonic stem cells emerge. Dr. West’s presentation will address BioTime’s recent research that has been directed towards the goal of generating highly purified, diverse, and scalable embryonic progenitor (EP) cell types for potential use in human cell therapy. The complete abstract of his presentation is available on the conference website at www.gtcbio.com. Dr. West’s presentation will be available on www.biotimeinc.com. About BioTime, Inc.

BioTime also plans to develop therapeutic products in China for the treatment of ophthalmologic, skin, musculo-skeletal system and hematologic diseases, including the targeting of genetically modified stem cells to tumors as a novel means of treating currently incurable forms of cancer through its subsidiary BioTime Asia, Limited. Our Singapore subsidiary, ES Cell International Pte Ltd, has been at the forefront of advances in human embryonic stem (“hES”) cell technology, being one of the earliest distributors of hES cell lines to the research community. ESI has produced clinical-grade human embryonic stem cell lines that were derived following principles of good manufacturing practice and currently offers them for potential use in therapeutic product development. In addition to its stem cell products, BioTime develops blood plasma volume expanders, blood replacement solutions for hypothermic (low temperature) surgery, and technology for use in surgery, emergency trauma treatment and other applications. BioTime's lead product, Hextend ®, is a blood plasma volume expander manufactured and distributed in the U.S. by Hospira, Inc. and in South Korea by CJ CheilJedang Corp. under exclusive licensing agreements.
