BioTime Reports First Complete Sequencing of the Nuclear Genome of Five GMP-Compliant Human Embryonic Stem Cell Lines at Jefferies 2011 Global Healthcare Conference

BioTime, Inc. (NYSE Amex:BTX) Chief Executive Officer, Michael D. West, Ph.D., will present today at the Jefferies 2011 Global Healthcare Conference in New York City at 1:00 p.m. EDT. His presentation will disclose commercial progress in each of the Company’s seven subsidiaries. Included in this update will be information on the first complete sequencing of the DNA of five human embryonic stem cell lines, demonstrating their normality and suitability for human therapeutic product development. Dr. West will also describe significant progress in the development by BioTime's subsidiary OrthoCyte Corporation of its HyStem^®-Rx, OTX-CP-03 and OTX-CP07 therapeutic products, as well as the development of novel potential broad-ranging cancer diagnostic products by the Company’s subsidiary OncoCyte Corporation.

A link to the live webcast of the company's presentation will be available at www.wsw.com/webcast/jeff60/btim/ and in the investors section of the Biotime website at www.biotimeinc.com. A replay will be available on the BioTime website for at least 30 days.

"The complete genome sequencing of our GMP-compliant bank of human embryonic stem cells is another step in the execution of our strategy of making our bank of GMP-compliant hES cell lines the industry standard for the development of a wide array of new human therapeutic products,” said Michael D. West, Ph.D., President and CEO of BioTime. "The complete genome sequence of the cells in our GMP Master Cell Bank is critically important given the high mutation rates seen in some induced pluripotent stem (iPS) cells recently reported in the scientific literature. We plan to publish complete details on the sequence analysis of our ESI embryonic stem cell lines and make publicly available the sequence variance files as soon as possible to aid researchers in the development of medical products with these cells.”
