脳や脊髄の外傷、脳血管障害、神経変性疾患などで、神経の軸索が損傷したり、神経が脱落したりすると、治癒することは困難である。神経系、特に中枢神経系では、一旦軸索が損傷したり、神経細胞死が生じたりした場合、神経が再生もしくは新生しないと考えられてきた。近年、中枢神経系でも神経を再生もしくは新生させることの可能性があることが明らかとされつつある。しかし、神経新生もしくは神経再生を、医療技術として使用する為の満足いく治療方法は現在無い。従って、安全性の高い神経新生及び/又は神経再生促進剤の開発が望まれている。   It is difficult to heal if nerve axons are damaged or nerves fall off due to trauma of the brain or spinal cord, cerebrovascular disorder, neurodegenerative disease, and the like. In the nervous system, particularly the central nervous system, it has been considered that once axons are damaged or nerve cell death occurs, nerves do not regenerate or regenerate. In recent years, it has been clarified that there is a possibility of regenerating or regenerating nerves in the central nervous system. However, there is currently no satisfactory treatment method for using neurogenesis or nerve regeneration as a medical technique. Therefore, development of a highly safe neurogenesis and / or nerve regeneration promoter is desired.
