OCEANSIDE, Calif.--(BUSINESS WIRE)--International Stem Cell Corporation (OTCBB:ISCO), www.internationalstemcell.com, the first company to perfect a method of creating human “parthenogenetic” stem cells from unfertilized eggs, announces the results of a second set of experiments confirming that its lab-grown corneal tissue closely mimics the drug absorption and drug metabolism characteristics found in normal corneal tissue. Other tests show that the stem cell derived corneal tissue refracts light, thus providing a further indication of its potential therapeutic value in treating corneal injury and disease.
