8只Wistar大鼠小脑创伤后移植同种新生鼠的小脑组织于伤口部位,4只损伤而无移植物作为对照,观察其对宿主的普金野氏细胞有丝分裂的影响。结果是普氏细胞的分裂有前中后及末四期,以中期最多,实验组分裂细胞的数量多于对照组。普氏细胞层的Bergmann星形胶质细胞和其它胶质细胞的分裂结果和数量同前且显著,表明移植物对宿主脑组织的细胞分裂有刺激促进作用。 Eight Wistar rats were implanted with cerebellum in the same kind of newborn rat’s cerebellum. Four rats were sacrificed without any graft as a control to observe the effect on the mitosis of the host. As a result, Platycodon cell division had the first, second and last four stages, with the largest amount in the middle stage, and the number of cleaved cells in the experimental group was more than that of the control group. The results and numbers of division and number of Bergmann astrocytes and other glial cells in the Platysma cell layer were the same as before and significant, indicating that the graft stimulated the cell division of host brain tissue.
