Objective To observe the effects of bone marrow stromal cells transplantation brain injury in rats, and to on vascularization after local investigate the mechanism of repairing by BMSC transplantation. Methods The animal model local brain injury in rat was established. The hBM- SCs were transplanted into the local brain. The immuno- histochemistry and reactance were used to observe endothelial cell and microcirculation of local brain. Results The hBMSCs were transplanted into the animal modd, the quantities and the expression of the FⅦ RAg positive cells increased and the microvascular structure was formed; the inside wall of the microvessel was smooth, the union between the ceils was firm; nucleuses were regularly organized, basement membranes were continued , and the vascular compression was relieved. Conclusion Local vascular endothelial cells were promoted to proliferate when hBMSCs were transplanted and the microvessel formed increaselly. Microcirculation of local brain was improved, and brain injury was repaired. 10 refs. 2 figs. 1 tab.
