摘要:
文题释义:
脊髓损伤:创伤等各种原因导致脊髓结构破坏、神经传导通路中断,由于中枢神经系统固有再生能力有限且损伤局部环境不利于再生,常导致永久性的神经功能缺陷。其病变与再生机制复杂,治疗需要从神经保护、解放神经再生潜力、对抗周围再生抑制环境等多方面进行。
间充质干细胞分泌组:是间充质干细胞分泌至细胞外空间的各种分子或细胞外囊泡,主要由间充质干细胞培养基去除杂质后获得,通过各种可溶性分子(如生长因子、趋化因子)及外泌体介导了间充质干细胞的大部分治疗作用,并且能避免细胞移植的各种弊端。
背景:由于中枢神经系统的固有再生能力有限,脊髓损伤常导致患者出现永久性的感觉、运动及自主神经功能障碍,严重影响其生活质量,目前临床上尚无有效改善神经功能恢复的方法。现研究认为间充质干细胞分泌组由于介导了细胞移植的主要治疗作用且避免了细胞排异等问题,因此将成为治疗脊髓损伤的有力工具。
目的:总结间充质干细胞分泌组治疗脊髓损伤的研究进展,并分析目前面临的问题及其未来发展方向。
方法:以“spinal cord injury,secretome”为关键词检索PubMed数据库,以“脊髓损伤,分泌组”为关键词检索CNKI、万方数据库,检索时限为2013年1月至2020年1月,排除与文章研究目的无关及重复性文章,纳入符合标准的71篇文献进行综述。
结果与结论:间充质干细胞分泌组中富含各种生长因子、神经营养因子等可溶性分子及细胞外囊泡,在减少细胞凋亡、调节免疫应答、抑制瘢痕形成、促进神经再生及血管形成方面都起到了显著作用。大量的研究表明,间充质干细胞分泌组可以促进脊髓损伤后的神经再生及功能恢复,且避免了细胞移植的种种弊端,未来将成为治疗脊髓损伤的可靠方法。

早期的研究主要将间充质干细胞的治疗效果归因于其多向分化能力,然而最近的研究表明移植后细胞不能长时间存活(通常小于1周),且全身注射情况下移植到受损部位的细胞数量稀少,其中大量研究发现单独使用细胞分泌到外界的成分甚至可以产生与细胞移植相当的治疗效果,因此越来越多的学者认为干细胞移植后分化起到的作用较小,其治疗效果可能来源于分泌到细胞外的分子,这些分子在细胞过程的调节中起到了关键作用。
