本研究结果表明,自体骨髓间充质干细胞移植到大鼠脑损伤部位显著改善脑组织病理变化和脑水肿,减少胶质细胞增殖,并增加脑源性神经营养因子的表达。此外,5-溴脱氧尿苷/胶质细胞酸性蛋白双标记的细胞和表达巢蛋白的细胞数量增加。最后,新的血管生成,大鼠表现出改善的运动和认知功能。这些结果表明,自体骨髓间充质干细胞移植促进脑外伤后的脑重塑并改善神经功能。
Results from the present study demonstrated that transplantation of autologous bone marrow-derived mesenchymal stem cells into the lesion site in rat brain significantly ameliorated brain tissue pathological changes and brain edema, attenuated glial cell proliferation, and increased brain-derived neurotrophic factor expression. In addition, the number of cells double-labeled for 5-bromodeoxyuridine/glial fibrillary acidic protein and cells expressing nestin increased. Finally, blood vessels were newly generated, and the rats exhibited improved motor and cognitive functions. These results suggested that transplantation of autologous bone marrow-derived mesenchymal stem cells promoted brain remodeling and improved neurological functions following traumatic brain injury.
