With recent patent expansions in both the U.S. and Canada this year for their stem cell technology platform, VistaGen is feeling supremely confident about the company's performance. CEO of VSTA, Shawn K. Singh, JD, even noted how the Canadian patent allowance in particular expands the company's core IP in a key target market the company has been after for years now. This particular patent, under exclusive license from the Icahn School of Medicine, Mount Sinai, New York, covers pluripotent stem cell culture systems which produce endoderm lineage cells, including liver, lung, pancreas, parathyroid, and thyroid cells.
