| 摘 要： | 目的观察Schwann细胞移植于电针损伤的中脑后是否有新生的髓鞘。方法新生大鼠坐骨神经Schwann细胞体外培养 ,5溴 脱氧尿嘧啶 (BrdU)标记后移植至电针损伤的大鼠中脑网状结构。免疫组织化学染色定位后行半薄切片 ,天青 美蓝髓鞘染色 ,油镜下观察新生的髓鞘。结果Schwann细胞移植后 8个月仍可见BrdU阳性细胞 ,并主要向大脑皮层迁移 ;在损伤的脑干区域内 ,移植后 1个月就可见新生的髓鞘。结论Schwann细胞移植可促进损伤的中枢神经系统再生 |

| Abstract: | Objective To investigate the remyelination after Schwann cells grafted into injured middle brain in rat.Methods Schwann cells originated from sciatic nerves of 1 to 2 day old rat were expanded and labeled by BrdU in vitro, transplanted into the rat middle brain injured by electric needle stimulus. Immunohistochemistry and myelin staining were used to locate in the BrdU positive cells and investigate remyelination.Results BrdU positive cells could be identified till at least 8 months after grafting, which mainly migrated toward injured ipsilateral cortex. New myelination could be seen in destructed brain stem area. Conclusion Schwann cells transplantation could promote CNS regeneration. |
