BioTime CEO Dr. Michael West to Present at USC Minisymposium: Musculoskeletal Development and Repair

ALAMEDA, Calif.--(BUSINESS WIRE)--May 20, 2013--BioTime, Inc. (NYSE MKT: BTX), a biotechnology company that develops and markets products in the field of regenerative medicine, today announced that Chief Executive Officer Michael D. West, PhD will present at the USC Minisymposium: Musculoskeletal Development and Repair conference at the Keck School of Medicine, the University of Southern California, on Monday, May 20, 2013. Dr. West’s presentation titled “Derivation of chondrogenic progenitor lines from human embryonic stem cells” is scheduled for 8:30 am PDT. Dr. West will describe BioTime’s novel and proprietary PureStem^TM technology which allows the industrial scale-up of over 200 different human cell types in a highly purified state from human embryonic stem cells. In addition, Dr. West will present new data on purified and scalable human embryonic progenitors with molecular markers corresponding to limb bud mesenchyme and will show differentiation data on those corresponding to the developing leg. These novel cells differ markedly from adult mesenchymal stem cells and may have novel applications in limb regeneration and the repair of disease and injuries to the weight-bearing joints. The presentation will be made available on BioTime's website at www.biotimeinc.com, and Dr. West discusses the cells in his weekly video update available for viewing at www.biotimeinc.com/video-series/.

The symposium is co-sponsored by the Eli and Edythe Broad Center and the Department of Orthopaedic Surgery of the University of Southern California.
