About International Stem Cell Corporation

International Stem Cell Corporation is focused on the therapeutic applications of human parthenogenetic stem cells (hpSCs) 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 for hundreds of millions of individuals of differing genders, ages and racial background with minimal immune rejection after transplantation. hpSCs offer 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.

International Stem Cell's Research Scientists Successfully Completed the First Series of Preclinical Animal Trials of Neuronal Cells

International Stem Cell Corporation (OTCBB: ISCO) announces today successful completion of the first series of preclinical studies designed to support the safety and utility of neuronal cells derived from human parthenogenetic stem cell line (hpSC). These initial experiments, demonstrating that the derived neuronal cells were able to survive in mice brains without giving rise to tumors, represent a key milestone towards possible therapeutic applications including treating Parkinson's disease.


Dr. Albrecht Müller, Professor at the Institute of Medical Radiology and Cell Research, Würzburg University (Germany), commented: "Human parthenogenetic stem cells are potentially very promising candidates for use in regenerative medicine primarily because of the possibility that they immune-match a large number of recipients. The result of these safety and survival studies is a very important step along the path towards the clinical use of such cells."


Although most cases of Parkinson's disease occur in people with no family history of the disease, a number of genetic mutations have nevertheless been identified with the disease. While the inheritance pattern is largely unknown, as a condition with a genetic component "autologous" treatment, that is to say treatment using the patient's own cells, is far from ideal and does not offer the potential of a cure. To treat Parkinson's disease successfully a source of cells free of the mutated genes is necessary. Human parthenogenetic stem cells provide this source, as well as superior immune-matching capabilities.


ISCO currently has the world's largest collection of human parthenogenetic stem cells including heterozygous examples, where the cells immune match the donor as is the case with induced pluripotent stem cells (iPS), and homozygous examples which immune-match millions of individuals. ISCO is actively expanding this collection of cell lines and creating a "bank" of homozygous human parthenogenetic stem cells that can be used as a platform to not only reduce the chances of tissue rejection, but also make cellular-based therapies economically more viable.


Dr. Ruslan Semechkin, ISCO's Vice President, commented: "One of ISCO's main therapeutic targets is treatment of Parkinson's disease, a common neurodegenerative disease in the US, where the current standard of care is designed mostly to treat the symptoms, but not the disease. These results clearly represent an important step towards the therapeutic application of human parthenogenetic stem cells derived cells in addressing the basic underlying mechanisms and potentially transforming the treatment of neurodegenerative diseases."

Forward-looking Statements
Statements pertaining to anticipated developments, research and development goals and related potential therapeutic treatments, the potential benefits of products, 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.

International Stem Cell Corporation Announces Second Quarter 2011 Financial Results and Corporate Events

International Stem Cell Corporation (OTCBB: ISCO), a biotechnology company that developed a powerful new stem cell technology called "parthenogenesis" which promises to significantly advance the field of regenerative medicine, today announced financial results for the quarter ended June 30, 2011 and for the first six months of the fiscal year and provided an update on corporate events.

ISCO reported year-to-date revenues of $2.6 million compared to $0.7 million for the same time period in 2010, representing an increase of 271%. The increase in our revenues relates to sales generated by ISCO's wholly-owned subsidiaries Lifeline Skin Care (LSC) which contributed $1.7 million and Lifeline Cell Technology (LCT) which contributed $0.9 million of revenues.

Total year-to-date expenses, excluding cost of sales increased $2.0 million or 38%, compared to the first six months of the previous year. The most significant reasons for the increase in total expenses related to increases in R&D and G&A. Research & Development expenses increased primarily due to increased activity on our scientific projects. General & Administrative expenses increased primarily due to increased headcount, non-cash stock-based compensation and increased expenses related to business development activity and general corporate expenses.

Our cash balance at June 30, 2011 was $3.6 million. Net cash used in operating activities for the six months ended June 30, 2011 was $3.0 million.

Second Quarter 2011 Highlights:

-- The first U.S.-based donor was enrolled in ISCO's program to establish a bank of clinical-grade human parthenogenetic stem cells (hpSCs) capable of being immune-matched to millions of patients.

-- We strengthened our senior management team to assist in the continued development of the Company. Kurt May was appointed Senior Vice President responsible for mergers and acquisitions and development of new international collaborations. Donna Queen was added to the management team as Vice President of LSC, where she is responsible for marketing and business development.

-- We started a series of preclinical animal studies of neuronal cells derived from hpSCs. The studies will evaluate the in vivo safety and tumorigenicity of neuronal cells as well as their ability to develop into functioning dopaminergic neuron–like cells to treat Parkinson's disease.

-- We successfully completed the first series of preclinical testing of hepatocytes derived from hpSCs. In the transplantation mouse model, inoculated cells were capable of engrafting and surviving in specific niches within the liver, and were further developing into cells with essential hepatocyte-like features.
