International Stem Cell Corporation Enrolls First Donor in Program to Create New Parthenogenetic Stem Cell Lines in the United States

CARLSBAD, Calif. -- (May 19, 2011) -- International Stem Cell Corporation (OTCBB:ISCO),, has now enrolled the first U.S.-based donor in its program to establish a bank of clinical-grade human parthenogenetic stem cells (hpSCs) capable of being immune-matched to millions of patients.

Dr. Simon Craw, Vice President of ISCO with primary responsibility for building its UniStemCell Bank, said, “Enrolling our first donor is a key milestone towards our goal of creating a bank of clinical-grade pluripotent human stem cells with the ability to immune-match millions of patients. It is extremely exciting to start this new phase of development, and I look forward to making new clinical-grade hpSC lines available to medical researchers around the world.”

ISCO maintains the world’s largest collection of research-grade human parthenogenetic stem cell (hpSC) lines which it uses along with its partners and collaborators to investigate cellular therapies for a number of incurable human diseases.

ISCO previously announced it had successfully obtained the necessary regulatory approvals for obtaining human oocytes, including Institutional Review Board (IRB) approval and Stem Cell Research Oversight (SCRO) committee approval. Today’s announcement marks the next phase of development as the Company is now positioned to begin producing new clinical-grade hpSC lines.

These new cell lines will be ISCO’s first hpSCs to be produced in the United States in accordance with Good Manufacturing Practice (cGMP) specifications. The new cGMP hpSC lines will be uniquely valuable in therapeutic research and clinical development as cells or tissue derived from such cells can be used in human clinical trials.

ISCO’s scientific discoveries have resulted in the development of a unique new type of pluripotent stem cells that possess a number of distinct advantages over other types of human pluripotent stem cells. ISCO uses unfertilized oocytes to create human “parthenogenetic” stem cells. Like human embryonic stem cells (hESCs), hpSCs are pluripotent, i.e. they have the capacity to become almost any cell type in the body, yet avoid ethical issues associated with use or destruction of viable human embryos. Unlike hESCs, hpSCs can be created in a form such that they can be immunologically matched to millions of individuals.

About International Stem Cell Corporation

International Stem Cell Corporation is focused on the therapeutic applications of human parthenogenetic stem cells and the development and commercialization of cell-based research and cosmetic products. ISCO's core technology, parthenogenesis, results in the creation of pluripotent human stem cells from unfertilized oocytes (eggs). hpSCs avoid ethical issues associated with the use or destruction of viable human embryos. ISCO scientists have created the first parthenogenic, homozygous stem cell line that can be a source of therapeutic cells with minimal immune rejection after transplantation into hundreds of millions of individuals of differing genders, ages and racial background. This offers the potential to create the first true stem cell bank, UniStemCell™. ISCO also produces and markets specialized cells and growth media for therapeutic research worldwide through its subsidiary Lifeline Cell Technology, and cell-based skin care products through its subsidiary Lifeline Skin Care.

Forward-looking Statements

Statements pertaining to anticipated developments, the potential production and benefits of stem cell lines, and other opportunities for the company and its subsidiaries, along with other statements about the future expectations, beliefs, goals, plans, or prospects expressed by management constitute forward-looking statements. Any statements that are not historical fact (including, but not limited to statements that contain words such as "will," "believes," "plans," "anticipates," "expects," "estimates,") should also be considered to be forward-looking statements. Forward-looking statements involve risks and uncertainties, including, without limitation, risks inherent in the development and/or commercialization of potential products and the management of collaborations, regulatory approvals, need and ability to obtain future capital, application of capital resources among competing uses, and maintenance of intellectual property rights. Actual results may differ materially from the results anticipated in these forward-looking statements and as such should be evaluated together with the many uncertainties that affect the company's business, particularly those mentioned in the cautionary statements found in the company's Securities and Exchange Commission filings.
