摘　　要：目的观察大鼠同种骨髓间充质细胞（BMSCs）经门静脉肝内移植对80％肝切除肝衰竭模型术后肝功能、生存率的影响。方法通过80％肝切除建立大鼠边缘肝衰竭模型，经门静脉输注绿荧光蛋白（GFP）标记的第5代（P5）大鼠同种MSC，观察BMSCs肝内移植对肝大部分切除边缘肝衰竭模型术后生存率、肝功能的影响。结果术后7d内的存活率：MSC组72．2％（13／18）、对照组44．4％（8／18）。MSC组的存活率明显高于对照组（72．2％比44．4％，P〈0．05；MSC组大鼠术后肝功能恢复情况明显优于对照组（P〈0．05）；MSC组肝组织中可观察到移植的细胞。结论经门静脉的BMSCs移植可促进80％肝切除边缘肝衰竭大鼠的肝功能恢复和提高生存率。Objective To investigate the effect of liver function and survival rate on allogeneic bone mesenchymal stem cells （BMSCs） transplantation through portal vein in the rat 80% hepatectomy model. Methods Build up the edge of limit hepatectomy rat model, transplant the 5th passage （P5） allogeneic rat BMSCs marked with green fluorescent protein （ GFP）, observe the effect of liver function and survival rate after allogeneic BMSCs transplantation through portal vein in the rat hepatectomy model. Resuits Survival rate after 7 days ： MSC Group 72. 2% （ 13/18）, control Group 44.4% （8/18）, The survival rate of MSC Group was significantly higher than control Group （72. 2% vs. 44. 4%, P 〈 O. 05 ） ; the liver function recovery after surgery of MSC Group is better than control Group （ P 〈 0. 05 ） ; transplanted BMSCs could be deteced in recipient liver of MSC Group. Conclusion BMSCs transplanted though portal vein can promote liver function recovery and improve survival rates in rat 80% hepatectomy model.
