摘要:

文题释义:
细胞自噬:是细胞在应激状态下通过膜结构将受损细胞器或蛋白质运送到溶酶体或自噬溶酶体,利用多种溶菌酶降解受损的物质,从而达到细胞新陈代谢和细胞器更新的过程。自噬参与细胞以及生物体的发育和分化的全过程,与细胞增殖以及损伤后修复等密切相关。
间充质干细胞:是一种能够进行自我更新并具有多向分化功能的成体干细胞,其可在体外实现轻松扩增,并能够选择性地迁移到受损组织附近分泌相应营养因子来修复组织缺损。

背景:近年来,间充质干细胞在创面愈合中的作用受到广泛关注。尽管间充质干细胞可以促进伤口愈合,但其作用机制并不完全十分清楚。
目的:对近年来间充质干细胞促进创面愈合的作用及其机制作一综述。
方法:以“间充质干细胞,创面愈合,自噬,干细胞”“mesenchymal stem cells,wound healing,autophagy,stem cells”为关键词,检索自建库以来至2021年3月在PubMed、Cochrane library、中国知网、维普中文科技期刊全文数据库、万方医学网、中国生物医学文献数据库等收录的相关文献。
结果与结论:间充质干细胞移植创面后,可通过调控自噬效应与创面环境互为影响,协调统一,共同促进创面组织的愈合。同时,间充质干细胞可作为理想的自噬诱导体,促进创面成纤维细胞的增殖和迁移,抑制炎症反应,促进内皮细胞的血管生成从而促进受损创面的愈合。然而,目前尚不清楚间充质干细胞对自噬活性的作用机制。因此,间充质干细胞植入创面中引起的自噬消除及相关分子机制成为当前创面愈合研究的重点。

Abstract: BACKGROUND: In recent years, the role of mesenchymal stem cells in wound healing has received widespread attention. Although mesenchymal stem cells can promote wound healing, its mechanism of action is not completely clear.
OBJECTIVE: To review the role and mechanism of mesenchymal stem cells in promoting wound healing in recent years.
METHODS: Using “mesenchymal stem cells, wound healing, autophagy, stem cells” as Chinese and English key words, related articles were searched on PubMed, Cochrane Library, CNKI, VIP, Wanfang Medical Network, China Biomedical Literature Database from the establishment of the database to March 2021. 
RESULTS AND CONCLUSION: Mesenchymal stem cells can promote wound healing by regulating autophagy and wound environment. At the same time, as a new method to promote wound healing, mesenchymal stem cells can be used as an ideal autophagy inducer to promote wound healing, promote the proliferation and migration of wound fibroblasts, inhibit inflammatory reaction, and promote the angiogenesis of endothelial cells, so as to promote the healing of injured wounds. However, the mechanism and promotion of mesenchymal stem cells on autophagy are still unclear. Therefore, the research of autophagy elimination and related molecular mechanism caused by mesenchymal stem cell implantation into wound has become the focus of current wound healing research.

Key words: autophagy, mesenchymal stem cells, wound, wound healing, review, stem cells, fibroblasts, blood vessel
