目前,周围神经损伤后的功能重建已成为国内外学者亟待解决的难题之一,自体神经移植仍然是最理想的方法。但是,自体神经来源受限,较粗的神经无法找到相应供体,且取材后导致新的功能损伤,因此不能广泛推广[1]。间充质干细胞(MSCs)因其具有易于取材、体外易于培养、低免疫原性、可分泌细胞因子、较强的分化能力、无伦理学争议等特点,成为组织工程人工神经良好的种子细胞。本文就间充质干细胞(MSCs) At present, the functional reconstruction after peripheral nerve injury has become one of the problems to be solved urgently by domestic and foreign scholars. Autologous nerve transplantation is still the most ideal method. However, limited sources of autologous nerves, coarser nerves can not find the corresponding donor, and lead to new functional damage after drawing, it can not be widely promoted [1]. Mesenchymal stem cells (MSCs) have become the tissue-engineered artificial neural good seed cells because of their characteristics such as easy to draw, easy to culture in vitro, low immunogenicity, secretable cytokines, strong differentiation ability and no ethical controversy. In this paper, mesenchymal stem cells (MSCs)
