NeuroSphere

NeuroSphere was a pioneering Canadian biotechnology company focused on the discovery and development of neural stem cell-based therapies for central nervous system (CNS) disorders. Founded in 1992 by Dr. Samuel Weiss and Dr. Brent Reynolds, the company was established following their landmark discovery of stem cells in the adult mammalian brain. NeuroSphere developed proprietary technologies for the isolation, proliferation, and differentiation of neural stem cells into functional neurons and glial cells. Its research programs targeted high-unmet-need conditions such as Parkinson's disease, multiple sclerosis, and spinal cord injuries. The company's innovative platform and extensive intellectual property portfolio were acquired by StemCells Inc. in 2005, integrating its foundational technology into a broader clinical development pipeline.
