International Stem Cell Corp Granted Key Patent for Liver Disease Program
News Sep 25, 2012
This patent is a key element of ISCO's metabolic liver disease program and allows the Company to produce the necessary quantities of precursor cells in a more efficient and cost effective manner.
The patent, 8,268,621, adds to the Company's growing portfolio of proprietary technologies relating to the development of potential treatments for incurable diseases using human parthenogenetic Stem Cells (hpSC). Human parthenogenetic stem cells are unique pluripotent stem cells that offer the possibility to reduce the cost of health care while avoiding the ethical issues that surround the use of fertilized human embryos. Aside from the Company's current liver disease program, this new patented method can be used as a route to create pancreatic and endocrine cells that could be used in future studies of diabetes and other metabolic disorders.
ISCO currently has the largest collection of hpSC including cell lines which immune match the donor, as is the case with induced pluripotent stem cells (iPS), and cell lines which immune-match millions of individuals and potentially reduce tissue rejection issues. The Company is focusing its therapeutic development efforts on three clinical applications where cell and tissue therapy is already proven but where there currently is an insufficient supply of safe and efficacious cells: Parkinson's disease, inherited/metabolic liver diseases and corneal blindness.
A new study has identified a drug that potentially could make a common type of immunotherapy for cancer even more effective. The study in laboratory mice found that the drug dasatinib, which is FDA-approved to treat certain types of leukemia, greatly enhances responses to a form of immunotherapy that is used against a wide range of other cancers.
A human pluripotent stem cell line has been engineered which contains two ‘suicide genes’ that induce cell death in all but the desired insulin-producing cells. This double fail-safe approach opens the door to creating safe cell-replacement therapies for people living with type 1 diabetes.READ MORE
