摘要:


文题释义:

外泌体:是一种直径在40-100 nm的细胞外盘状囊泡。外泌体携带的生物活性物质的类型及功能根据细胞类型的不同而有所不同,主要包括DNA、RNA、蛋白质、脂质、细胞因子等,是细胞间信息交流的重要组成部分。目前外泌体是疾病诊断与治疗、靶向给药、生物疫苗、组织修复再生等领域研究的热点。
皮肤创伤修复:是一个复杂的组织修复和重塑过程,涉及炎症反应、细胞增殖和迁移、细胞外基质合成和沉积、血管生成和重塑等生物学进程,需要通过依靠各种类型细胞在时间和空间的紧密协调才能有效恢复受损组织的外观和功能。修复过程受多种内源性及外源性因素影响,若伤口修复相关细胞行为和功能紊乱可导致伤口愈合不良,甚至无法愈合。


背景:外泌体在创伤修复的所有阶段均有作用,目前已有大量外泌体应用于皮肤创伤修复的研究且被证实具有极大的应用潜力。

目的:总结与探讨外泌体治疗皮肤创伤的主要机制及临床应用现状,以促进外泌体的临床转化。
方法:检索PubMed数据库、clinicaltrials.gov数据库、中国知网数据库、美国食品药品监督管理局数据库和中国临床试验注册中心,检索时限为各数据库建库至2023年3月,英文检索关键词为“exosomes,wound healing,stem cells,chronic wound,immunoregulation,inflammation,skin,therapeutic use,isolation,characterization,infections”,中文检索关键词为“外泌体,创伤修复,干细胞,免疫调节,临床应用”,最终纳入79篇文献进行总结。

结果与结论:①外泌体能通过炎症调节、免疫保护、血管生成、细胞增殖和迁移、胶原重塑失衡调节等方式改善和加速创面愈合。②干细胞源外泌体制备技术、相关机制研究均较为成熟,是目前主流的研究方向。非干细胞外泌体有方便、经济、易于生产等优点,可作为临床应用的补充。③外泌体的临床应用仍处在起步阶段,但具有极大的应用潜力。各种外泌体改良技术为未来开拓临床个性化服务奠定了基础,需要进一步研究。④外泌体的临床转化面临诸多挑战,如:产量低,高度异质性,未建立统一的分离、纯化和质量控制标准,储存困难等。

Abstract: BACKGROUND: Exosomes play a role in all stages of wound repair, and there is currently a large body of research on exosomes in skin wound repair, which has been shown to have great potential for clinical applications. 
OBJECTIVE: To summarize and discuss the main mechanisms and clinical applications of exosomes in the treatment of skin wounds, in order to promote the clinical translation of exosomes. 
METHODS: PubMed, clinicaltrials.gov, China National Knowledge Infrastructure, Food and Drug Administration database, and Chinese Clinical Trial Register were searched from inception to March 2023. The English search terms were “exosomes, wound healing, stem cells, chronic wound, immunoregulation, inflammation, skin, therapeutic use, isolation, characterization, infections”. The Chinese search terms were “exosomes, wound healing, stem cells, immunomodulation, clinical applications”. A total of 79 articles were included for the summary. 
RESULTS AND CONCLUSION: (1) Exosomes can improve and accelerate wound healing through inflammation regulation, immune protection, angiogenesis, cell proliferation and migration, and collagen remodeling. (2) Exosomes derived from stem cells have mature preparation techniques and related mechanism research, which is currently the mainstream research direction. Non-stem cell-derived exosomes have the advantages of convenience, economy, and easy production, and can be used as a supplement for clinical applications. (3) The clinical application of exosomes is still in its infancy, but has great potential for application. Various exosome modification techniques have laid the foundation for the future development of clinically personalized services and require further research. (4) The clinical translation of exosomes faces many challenges, such as low yield, high heterogeneity, lack of unified standards for isolation, purification, and quality control, and difficulties in storage. 

Key words: exosome, wound healing, stem cell, immunoregulation, cell proliferation, clinical application, tissue engineering, review
