About International Stem Cell Corporation (ISCO.OB):

International Stem Cell Corporation (ISCO) is a California biotechnology company focused on developing therapeutic and research products. ISCO's technology, Parthenogenesis, results in the creation of pluripotent human stem cell lines from unfertilized human eggs. ISCO scientists also have created the first Parthenogenetic homozygous stem cell line (phSC-Hhom-4) that can be a source of therapeutic cells that will not be immune rejected after transplantation into millions of individuals of differing sexes, ages and racial groups. These advancements offer the potential to create the first true "Stem Cell Bank" and address ethical issues by eliminating the need to use or destroy fertilized embryos.
