摘要:

背景:干细胞在一定诱导条件下可分化成为血管性内皮细胞,促进缺血下肢血管新生和有效循环的建立,改善糖尿病远端缺血肢体供血。

目的:概述脐带间充质干细胞生物学特性、促血管新生的机制,探讨脐带间充质干细胞修复神经病变及慢性创面等基础研究和临床研究现状。

方法:检索2000至2015 年PubMed 数据库、维普中文科技数据库及万方数据相关文献。英文检索词为“stem cells transplantation,umbilical Cord Mesenchymal Stem Cell,diabetic angiopathies”;中文检索词为“干细胞移植,脐带间充质干细胞,糖尿病血管病变”。

结果与结论:与目前外周血干细胞及骨髓间充质干细胞移植相比,脐带间充质干细胞来源更广泛,采集方便,扩增能力强,无免疫原性,不存在伦理学争议,成为促血管新生和基因治疗缺血性疾病的理想靶细胞和种子细胞。脐带间充质干细胞能够分化为血管内皮细胞和成纤维细胞参与创面愈合,也可促进神经营养因子表达,促进缺血组织神经再生,并通过旁分泌与自分泌细胞因子、抗炎及免疫调节等参与受损组织的组织修复,加快溃疡面愈合,对于改善糖尿病下肢缺血、修复糖尿病周围神经病变和促进慢性溃疡创面愈合等治疗中具有广阔的应用前景。与单纯的干细胞移植比较,脐带间充质干细胞联合细胞因子基因治疗可进一步提高干细胞存活率及促进血管新生。

Abstract:

BACKGROUND: Under certain conditions, stem cells can be induced to differentiate into vascular endothelial cells, which can promote the angiogenesis of ischemic lower limbs and the establishment of effective circulation and improve distal blood supply of the ischemic limbs.

OBJECTIVE: To review the biological characteristics and pro-angiogenesis mechanism of umbilical cord mesenchymal stem cells and to investigate the current status of umbilical cord mesenchymal stem cells in the repair of neuropathy and chronic wounds.

METHODS: PubMed, VIP and Wanfang databases were searched for relevant articles published from 2000 to 2015 using the keywords of “stem cells transplantation, umbilical cord mesenchymal stem cell, diabetic angiopathies” in English and Chinese, respectively.

RESULTS AND CONCLUSION: Compared with peripheral blood stem cells and bone marrow mesenchymal stem cells, umbilical cord mesenchymal stem cells are characterized as more widespread sources, easy collection, stronger amplification ability, no immunogenicity, and no ethical controversy, which have become ideal target and seed cells for pro-angiogenesis and gene therapy in ischemic diseases. Umbilical cord mesenchymal stem cells can differentiate into vascular endothelial cells and fibroblasts involved in wound healing. In addition, these cells can promote the production and expression of neurotrophic factors, promote nerve regeneration in ischemic tissues, and participate in tissue repair and accelerate healing of ulcers by paracrine and autocrine cytokines, anti-inflammation and immunomodulation. Therefore, umbilical cord mesenchymal stem cells have a broad prospect in the improvement of diabetic lower limb ischemia, repair of diabetic peripheral neuropathy and promotion of chronic ulcer healing. Compared with stem cell transplantation alone, umbilical cord mesenchymal stem cells transplantation combined with gene therapy can further enhance cell survival and pro-angiogenesis.
