California Stem Cell (CSC) is a privately held company focused on the manufacture and supply of high-purity human cells for basic research and therapeutic development.

Since its founding in 2005, CSC has developed proprietary methods for the scalable production of human motor neurons and neuronal progenitors, at high purity, from hESCs. The ability to generate these cell types at high-purity in large quantities has put CSC in the unique position to address critical unmet needs in drug discovery and the development of life-changing therapies. CSC is currently developing stem cell based therapies as clinical candidates for the treatment of spinal muscular atrophy (SMA), amyotrophic lateral sclerosis (ALS, or Lou Gehrig’s Disease), and metastatic cancer.
