▎ 摘　　要

NOVELTY - Producing nerve cell, comprises applying an electromagnetic field to a graphene structure in contact with the cell to reprogram the cell into a nerve cell. USE - The method is useful to produce nerve cell as cell therapy agent and composition for preventing and treating cranial nerve disease including Alzheimer's disease, Parkinson's disease, Pick's disease, Huntington's disease, amyotrophic lateral sclerosis, spinal nerve injury, encephalitis, multiple sclerosis, cerebral ischemia, epilepsy, stroke and traumatic brain injury (all claimed). ADVANTAGE - The method produces nerve cell efficiently for stem cells having self-renewal ability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for cell therapy agent comprising nerve cell produced by the above method.
