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.

脚有人体的“第二大脑”之称。人的足由上百块肌腱33个关节和韧带组成,脚底的韧带紧连着跟骨的底端。
痛风之痛: 尿酸盐在体内大量沉积形成结晶,体表、手脚关节部位会慢慢长出痛风石,时间长了会导致关节破坏、关节畸形,影响正常功能。尿酸盐长期沉积在肾脏,会引发痛风性肾病,严重的甚至导致尿毒症。
