VistaGen expands stem cell patent portfolio

VistaGen Therapeutics, Inc. said the US Patent and Trademark Office (USPTO) issued it a patent “related to methods for producing, from human pluripotent stem cells (hPSCs), hematopoietic precursor stem cells, which are stem cells that give rise to all of the blood cells and most of the bone marrow cells in the body.”

VistaGen holds an exclusive license to this patent from the University Health Network (UHN).

VistaGen is a clinical-stage biopharmaceutical company focused on developing new generation medicines for depression and other central nervous system (CNS) disorders.

“The technology covered by the issued U.S. patent has the potential to impact both direct and supportive therapy for autoimmune disorders and cancer, with CAR-T cell applications, and foundational technology which may provide approaches for producing bone marrow stem cells for bone marrow transfusions,” said VistaGen.

Dr. Gordon Keller, Director of the McEwen Centre for Regenerative Medicine in Toronto, one of the world’s leading centers for stem cell and regenerative medicine research and part of the University Health Network (UHN), discovered the stem cell technology covered by this patent.
