摘要:

背景:循环纤维细胞是近些年来在外周血液发现的具有成纤维细胞特性的一种白细胞亚群,由于具有合成多种细胞外基质蛋白、细胞因子以及递呈抗原、收缩创面、促进新生血管形成的能力,因此被认为可以促进创伤的修复。但其促进慢性创面修复的潜在作用研究尚少。
目的:通过文献检索,对循环纤维细胞的生物学特性及其在慢性创面修复中的潜在作用进行文献综述。
方法:分别以“循环纤维细胞、慢性创面、糖尿病足、创面愈合、细胞治疗”和“circulating fibrocytes、An-healing wounds、diabetic foot ulcer、wound healing、cell therapy”为关键词进行检索,CNKI数据库的检索时限为2000至2014年,PubMed数据库的检索时限为1994至2015年,西文生物医学期刊文献数据的检索时限为2000至2015年,检索内容为循环纤维细胞、慢性创面的难愈机制以及细胞治疗在慢性创面愈合中的应用。保留符合纳入标准的54篇文献进行总结分析。
结果与结论:循环纤维细胞因其安全、有效并能较好的发挥促进创面愈合的作用,细胞治疗已开始应用于创面修复。循环纤维细胞是在外周血发现的具有成纤维细胞特性的一个新型白细胞亚群,具有合成多种细胞外基质蛋白、细胞因子以及递呈抗原、收缩创面、促进新生血管形成的能力并在伤后早期进入损伤部位,在创伤修复过程中发挥着积极作用。动物研究证实,应用循环纤维细胞可改善慢性创面尤其是糖尿病慢性创面的修复。

Abstract:

BACKGROUND: Circulating fibrocytes originated from the peripheral blood are a fibroblast-like cell subpopulation of leukocytes. Circulating fibrocytes play an essential role in wound repair by secreting extracellular matrix proteins and cytokines, initiating antigen-specific immunity, accelerating wound contraction as well as promoting angiogenesis. However, the potential role for improving chronic wound healing and its mechanism is still unclear.
OBJECTIVE: To summarize the biological features of circulating fibrocytes and its potential role and mechanism in accelerating chronic wound healing.
METHODS: A computer-based search of CNKI database from 2000 to 2014, PubMed database from 1994 to 2014 and Foreign Medical Journal Full-Text Service database from 2000 to 2014 was performed using “circulating fibrocytes, non-healing wounds, diabetic foot ulcer, wound healing, cell therapy” in Chinese and English as the keywords to retrieve articles related to circulating fibrocytes, refractory mechanism of chronic wound healing and cell therapy for chronic wounds. Totally 54 articles meeting the inclusive criteria were included in result analysis.
RESULTS AND CONCLUSION: Cell therapy with circulating fibrocytes is a safe and effective treatment for improving wound healing and has been used to repair various chronic wounds in the recent decades. Circulating fibrocytes are a distinct subpopulation of fibroblast-like leukocytes in the peripheral blood. It is able to migrate into wound sites at the early stage of wound repair and plays an active role in the wound healing process by secreting extracellular matrix proteins, cytokines, presenting antigens, contracting wound and promoting neovascularization. Recently, it has been proved in animal experiments that circulating fibrocytes can accelerate chronic wound healing, especially diabetic chronic wound.
