中枢神经系统(大脑和脊髓)几乎没有再生能力。但近十多年来发现,它能使得移植物存活。通过鼠的一系例实验表明,胚胎脑组织植入成年哺乳动物的中枢神经系统,能存活及发育成熟,并与宿主在解剖和功能上协调,移植物与宿主的效应充分地显示了调节中枢神经系统发育和再生的许多因素。动物实验表明,中枢神经系统移植可能不会产生免疫排斥反应,尤其在应用免疫抑制剂如环磷(?)胺 The central nervous system (brain and spinal cord) has almost no regenerative capacity. However, it has been found for over a decade that it can make the graft survive. Through a series of experiments on mice, it shows that embryonic brain tissue is implanted into the central nervous system of adult mammals, which can survive and mature, and is anatomically and functionally coordinated with the host. The effects of the graft and the host fully show that the regulatory center Numerous factors of nervous system development and regeneration. Animal experiments show that central nervous system transplantation may not produce immune rejection, especially in the use of immunosuppressive agents such as cyclophosphamide
