日本一项最新研究发现了抑制哺乳动物中枢神经细胞再生的主要原因,以及克服这一障碍让中枢神经细胞再生的方法。这项成果将有助于脊髓损伤患者的治疗。手脚等处的末梢神经即使受损也会慢慢再生,而脑和脊髓等部位的中枢神经几乎不会再生。脑梗死和脊髓损伤后往往留下身体麻痹等重度后遗症,其重要原因是,中枢神经受损部位附近的星形胶质细胞会形成名为胶 A new study in Japan found the main reasons for the inhibition of CNS regeneration in mammals and how to overcome this obstacle to regenerate CNS cells. This result will help treat patients with spinal cord injury. The peripheral nerve such as hands and feet will regenerate slowly even if it is impaired, whereas the central nervous system such as brain and spinal cord will scarcely regenerate. Cerebral infarction and spinal cord injury tend to leave severe sequelae such as paralysis of the body, the important reason is that the astrocytes near the damaged parts of the central nervous system will form a gel called
