摘要:

实验假设化学去细胞异体神经联合骨髓间充质干细胞移植能够有效修复长距离坐骨神经,拟以数学模型和力学变化验证。制备家兔坐骨神经30mm的损伤模型,分别以自体神经移植、化学去细胞异体神经移植、化学去细胞异体神经联合骨髓间充质干细胞移植进行修复。结果发现,化学去细胞异体神经联合骨髓间充质干细胞移植的坐骨神经拉伸性能、电生理功能及形态均优于单纯以化学去细胞异体神经移植修复的损伤坐骨神经,且上述指标与自体神经移植效果接近。提示化学去细胞异体神经联合骨髓间充质干细胞移植有用于修复长距离坐骨神经缺损临床应用的前景。

Abstract:

We hypothesized that a chemically extracted acellular allogeneic nerve graft used in combination with bone marrow mesenchymal stem cell transplantation would be an effective treatment for long-segment sciatic nerve defects. To test this, we established rabbit models of 30 mm sciatic nerve defects, and treated them using either an autograft or a chemically decellularized allogeneic nerve graft with or without simultaneous transplantation of bone marrow mesenchymal stem cells. We compared the tensile properties, electrophysiological function and morphology of the damaged nerve in each group. Sciatic nerves repaired by the allogeneic nerve graft combined with stem cell transplantation showed better recovery than those repaired by the acellular allogeneic nerve graft alone, and produced similar results to those observed with the autograft. These fndings confrm that a chemically extracted acellular allogeneic nerve graft combined with transplantation of bone marrow mesenchymal stem cells is an effective method of repairing long-segment sciatic nerve defects.
