应用不同胎龄的大鼠小脑组织(E_(15)和E_(18))植入受体鼠小脑,成活1～2个月后处死动物。光镜下观察移植物成活情况。移植物总成活率为35％。E_(15)成活率(60％)高于E_(18)(10％)。所有成活的移植物可根据细胞结构的特点易与受体脑组织区别,镜下可见到良好分化及成熟的神经细胞。
The cerebellum of rats (E_ (15) and E_ (18)) of different gestational age were implanted into the cerebellum of the recipient mice and the animals were sacrificed after 1-2 months of survival. Light microscopic observation of graft survival. The graft survival rate was 35%. The survival rate of E_ (15) was higher than that of E_ (18) (10%). All living grafts can be distinguished from the recipient’s brain tissue according to the characteristics of the cell structure. Microscopically, well-differentiated and mature neurons can be seen.
