MENLO PARK, Calif.--(BUSINESS WIRE)--Geron Corporation (Nasdaq: GERN) today announced data on the use of GRNOPC1, oligodendrocyte progenitors derived from human embryonic stem cells, for myelin repair in a non-human primate model. The data supports further investigation of the potential therapeutic use of GRNOPC1 in central nervous system (CNS) disorders where the central or contributing pathology is destructive removal of myelin from nerve axons, such as observed in multiple sclerosis (MS), myelitis and spinal cord injury. GRNOPC1 is currently in a Phase 1 clinical trial in patients with spinal cord injury.
