| 摘 要： | 目的观察骨髓基质细胞(BMSCs)移植对局灶性脑损伤大鼠损伤局部脑组织血管内皮细胞生长因子(VEGF)表达的影响。方法制备大鼠局灶性脑损伤动物模型,进行BMSCs移植,通过免疫组织化学、荧光定量PCR、ELISA等方法观察移植局部脑组织VEGF以及VEGF mRNA的变化。结果BMSCs移植后,局部VEGF染色阳性细胞数增加;VEGF mRNA含量增高。结论BMSCs移植可促进内源性VEGF的表达,提高损伤局部VEGF的含量。

| Abstract: | Objective To observe the effects of transplantation of bone marrow stromal cells(BMSCs)on expression of vascular endothelial growth factor(VEGF)after local brain injury in rats.Methods The animal model of local brain injury in rat was established.The human BMSCs(hBMSCs)were transplanted into the local brain.The immunohistochemistry,real-time quantitative PCR,and ELISA were used to observe the changes of VEGF and VEGF mRNA in tissues of local brain.Results After the hBMSCs were transplanted into the animal model,the quantities of the VEGF positive cells increased;real-time quantitative PCR showed that VEGF mRNA of local brain was enhanced.Conclusion The BMSCs transplantation can improve expression of endogenous VEGF and raise the content of VEGF in injured tissues of brain. |
