摘要
目的探讨骨髓间充质干细胞(mesenchymal stemcells,MSCs)源神经细胞脑内移植对帕金森病(Parkinson s disease,PD)大鼠的治疗作用。方法贴壁培养法分离、培养大鼠骨髓MSCs,脑匀浆上清诱导第3代MSCs向神经细胞分化,采用免疫细胞化学法鉴定诱导分化后细胞的性质,激光共聚焦显微镜检测诱导前后细胞Ca2+浓度变化,6只PD大鼠行纹状体内MSCs源神经细胞移植作为细胞移植组,6只PD大鼠作为对照组。细胞移植术后4周检测PD大鼠的行为变化,观察移植细胞在脑内的分布情况。结果倒置显微镜下可见MSCs呈纺锤形和多角形,有1~2个核仁,MSCs经脑匀浆上清诱导后其胞体折光性增强,发出数个细长突起,互相交织成网,有的似轴突。诱导后细胞表达神经元特异性标志物神经元特异性烯醇化酶(NSE)和神经丝蛋白(NF),胞质Ca2+荧光强度显著增强,可推测诱导后的细胞为MSCs源神经细胞,将BrdU标记的MSCs源神经细胞移植到PD大鼠纹状体治疗4周后,可见细胞散在分布于注射侧脑组织,有少量细胞可迁移到对侧脑组织,PD大鼠的旋转行为得到显著改善。结论MSCs源神经细胞移植治疗帕金森病大鼠可使其旋转行为得到改善。
