Abstract
Background: Full-thickness wounds severely affect patients’ life quality and become challenging problems for clinicians. Stem cells have great prospects in the treatment of wounds. Our previous study confirmed that autologous basal cell suspension could promote wound healing, and epidermal stem cells (ESCs) were detected in the basal cell suspension. Herein, this study aimed to explore the effect of ESCs on full-thickness wounds.
Methods: Rat ESCs were isolated and expanded and then were transfected with lentivirus to stably express enhanced green fluorescent protein. The experimental rats were randomly divided into 2 groups: in the ESC group, the rat ESCs were sprayed on the full-thickness wounds of rats; in the control group, phosphate-buffered saline was sprayed the on the wounds. Next, wound healing and neovascularization were evaluated. Colonization, division, and differentiation of ESCs on the wound were analyzed by immunofluorescence.
Results: The rat ESCs colonized, divided, and proliferated in the wound. Additionally, rat ESCs around blood vessels differentiated into vascular endothelial cells and formed a lumen-like structure. Compared with the control group, the ESC group showed enhanced angiogenesis and accelerated wound healing.
Conclusions: Our study confirmed that rat ESCs are safe and effective for treating full-thickness wounds. Additionally, under certain conditions, ESCs can differentiate into vascular endothelial cells to promote angiogenesis and wound healing.
Keywords: ESCs, Cell differentiation, Angiogenesis, Full-thickness wounds

糖尿病足部的慢性溃疡是否存在感染,好像应该是没有多少疑问的,但在所谓的“神经性溃疡”的表面是否存在有临床意义的感染,一直有争议。
对于外周血管病变的介入治疗,较IWGDF指南较有关OFFLOADING的细节描述,有关介入治疗的部分实在是比较粗慥,目前糖尿病外周血管病变介入治疗的热点问题大部分都没有涉及
对于糖尿病外周血管病变的治疗,2019年版IWGDF指南讲的比较少,无论是内科治疗还是介入治疗,这版的指南都讲得比较少(其实之前版本的IWGDF指南有关血管病变方面的内容更少),而国内糖尿病足指南,提到有关糖尿病外周血管病变治疗,一般都会用比较大的篇幅谈到其内科治疗。
人们对于糖尿病外周血管病变越来越关注,一方面,它是糖尿病足形成的最重要的原因;另一方面,它也是糖尿病进展到一定程度的标志,严重的糖尿病外周血管病变,往往标志着糖尿病进展到晚期,心、肾、脑、眼底等重要脏器的血管也存在严重的问题,而糖尿病足长期的皮肤溃疡不愈合,其产生的大量炎症因子,也会加重这些血管病变,因此,如何评价(诊断)及治疗糖尿病外周血管病变,成为了糖尿病诊断和治疗的最重要的领域。
