Exhibit 99.1

BioTime Announces the Closing of the Merger of Glycosan BioSystems with OrthoCyte Corporation

William P. Tew, Ph.D. Becomes Vice President, Business Development of BioTime and OrthoCyte

ALAMEDA, Calif.--(BUSINESS WIRE)--March 22, 2011--BioTime, Inc. (NYSE Amex: BTX), a biotechnology company that develops and markets products in the fields of stem cells, regenerative medicine and blood plasma volume expanders today announced it has completed the merger of Glycosan BioSystems, Inc. into BioTime’s wholly-owned subsidiary OrthoCyte Corporation. The definitive merger agreement was previously announced on February 14, 2011.

OrthoCyte was formed in 2010 to develop cell-based therapies for the treatment of orthopedic disorders. The Company has compiled animal preclinical data on two tissue engineered therapeutic product candidates designated OTX-CP03 and OTX-CP07, formulated in Glycosan’s HyStem^®-C hydrogel. The data shows initial evidence of safety and efficacy in animal models of osteoarthritis. The acquisition of Glycosan will provide OrthoCyte with HyStem^® intellectual property for use in formulating its orthopedic therapeutics, as well as the ability to sell or sublicense the products to other companies within and outside the BioTime family for other therapeutic uses. OrthoCyte also will continue to market the portfolio of Glycosan products for research use. (See www.glycosan.com.)

Established in 2006, Glycosan has been a leader in developing, manufacturing, and marketing proprietary biocompatible hydrogels that mimic the human extracellular matrix (ECM). The human ECM is a web of molecules surrounding cells that is essential to the formation, function, and growth of discrete tissues and organs in the body. Glycosan's HyStem^® hydrogels are dynamic products that have the demonstrated ability to support the growth and directed differentiation of stem cells, and are designed as injectable, resorbable matrices for tissue engineering, regenerative medicine, and for research applications involving the laboratory culture of human cells. Glycosan’s HyStem^® technology has been reported on in over 90 scholarly publications and is presently being used at several leading medical institutions to develop cell-based therapies for osteoarthritis, myocardial infarct, stroke, brain tumors, and wound healing. HyStem^® offers a convenient delivery matrix and its in situ polymerization creates a biocompatible, resorbable, scaffold for cell proliferation and tissue regeneration. Founder, President and CEO of Glycosan, William P. Tew, Ph.D., has become Vice President, Business Development for both BioTime and OrthoCyte.

“Glycosan’s products give BioTime and our subsidiaries a broad platform for advancing our therapeutic product development,” said Michael D. West, Ph.D., President and Chief Executive Officer of BioTime. “In addition to using HyStem^® hydrogels in combination with our proprietary ACTCellerate^™ human progenitor cell types, we will be testing HyStem^®-Rx as a stand-alone cell delivery device that can be used in reconstruction and cosmetic surgery. Regulatory approval of such an application would potentially accelerate revenue generation for BioTime as well as speed the development of our cellular therapeutics.”

“As an example of the many important uses of HyStem^® hydrogels in regenerative medicine, university researchers are using both the research-grade versions of our GMP human embryonic stem cell lines and HyStem^® in their work,” concluded Dr. West. “We believe the combination of BioTime’s ACTCellerate™ cell lines and Glycosan’s HyStem^® products will have applications in several therapeutic areas and will be attractive to many researchers seeking a faster path to delivering therapies for application in degenerative diseases.”

“The merger with OrthoCyte allows us many opportunities including the potential to help develop therapeutics for age-related degenerative diseases,” said Dr. Tew. “Our products can bring researchers closer to finding cures for degenerative diseases that will be afflicting an ever-growing number of people because of the demographic shift known as the ‘age wave.’ We’re excited to be part of this revolution in regenerative medicine and I’m personally excited about finding partners and new technologies for BioTime and OrthoCyte.”

Under the terms of the Agreement and Plan of Merger, Glycosan stockholders will receive, in the aggregate, approximately 332,906 BioTime common shares, and warrants to purchase approximately 206,612 additional BioTime common shares at an exercise price of $10 per share. Following completion of the merger, BioTime will continue to own 100% of the outstanding shares of OrthoCyte.
