International Stem Cell Corporation (OTCBB: ISCO) today announced the Company's near-term marketing plans for products manufactured by its Lifeline Skin Care™ (Lifeline) subsidiary. Following the highly successful launch in late 2010 of Lifeline's first two products with sales that greatly exceeded expectations, Lifeline has now commenced a new phase in the marketing plan for its skin care products.

The first step in these initiatives is a series of briefings being conducted in New York City this week with editors at beauty magazines whose readership reflects the target user base for Lifeline's anti-aging skin care products. This will be followed by a series of targeted email offerings developed by Lifeline's marketing partner, The Mauldin Companies, culminating in a larger offering in June.

Lifeline's anti-aging products were developed by ISCO's scientific research team in collaboration with internationally recognized cosmetic experts. The first two products, a Day Serum and a Night Serum, both contain an extract from ISCO's proprietary human parthenogenetic stem cells which, in combination with vitamin complexes, provides major rejuvenating effects, including improvement in skin tone and elasticity, and improvement in the appearance of fine lines and wrinkles. These effects have been substantiated by clinical studies performed at industry-leading independent testing organizations.

Lifeline's premium product line includes the Recovery Night Moisture Serum and the Defensive Day Moisture Serum/SPF-15. These products are most commonly ordered together in a 2-pack, and can be purchased by visiting Lifeline's website athttp://www.lifelineskincare.com. The products are also available at selected luxury spas and physician's offices in the United States.

Dr. Ruslan Semechkin, President and CEO of Lifeline Skin Care, added that Lifeline plans to launch additional skin care products later this year, including an eye cream formulated with a proprietary stem cell derivative and a cleanser.

Lifeline is focusing its marketing on direct-to-consumer channels to highly targeted audiences with traditional print and media promotions planned for later in the year. The Company's goal is to generate favorable word-of-mouth through a network of satisfied customers, thereby building a community of users based on their shared experience of success with Lifeline's proprietary anti-aging products.

Ken Aldrich, Co-founder and Chairman of Lifeline's parent company, International Stem Cell Corporation, said, "The success of Lifeline Skin Care demonstrates that we can make a positive difference in people's lives today, while also providing an important source of revenue to support ISCO's development of stem cell therapies that may in the future result in treatment for many widespread human diseases."

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.
