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

如果说大拇指占了人手功能的50%以上的功能,那么足的大趾的功能并没有那么大的作用,实际上,为了追求足底的平面,这三个支撑点的功能都非常重要。
足部对于一个人来说最重要的功能就是站立和行走,这些功能对于一个人来说是非常重要的,没有站立和行走的功能,就意味着这个人无法生活自理,无法工作,需要其他人的照顾,生活质量的急剧下降。
有关糖尿病足这个顽疾,国内外学界最近几年出了很多的指南、专家共识,对于几个比较重要的指南(包括对于2019年版IWGDF糖尿病足指南、2015年版IWGDF糖尿病足指南、中华医学会糖尿病分会糖尿病足及周围血管病变学组等)进行研读之后,有这么几个印象。
2019年版IWGDF有关糖尿病足指南特别推荐的SINBAD系统是指对糖尿病足以下的一些指标进行评价后的分类:Site(位置)、Ischemia(缺血)、Neuropathy(神经病变)、Bacterial infection(细菌感染)、Area(面积)、Depth(深度)。
伤口世界平台生态圈,以“关爱人间所有伤口患者”为愿景,连接、整合和拓展线上和线下的管理慢性伤口的资源,倡导远程、就近和居家管理慢性伤口,解决伤口专家的碎片化时间的价值创造、诊疗经验的裂变复制、和患者的就近、居家和低成本管理慢性伤口的问题。
