Abstract:
Skin epidermis is a continuous self-renewal tissue maintained by interfollicular epidermal stem cells (IESCs) that reside in the basal layer of epidermis. IESCs also contribute to the repair and regeneration of the epidermis during wound healing. The great plasticity and easy accessibility afforded by IESCs make them a promising source of stem cells for scientific research and clinical applications. Thus, simple methods to isolate and define pure and viable IESCs are a valuable resource. Here, we provide a method for isolating IESCs from human skin epidermis. This method relies exclusively on selecting cells with a higher expression of the endothelial protein C receptor, using fluorescence-activated cell sorting.

GPCRs are also called heptahelical, 7TM, or serpentine receptors, and consist of seven (H1-H7) transmembrane alpha-helices that span the bilayer to form a cylindrical core. The transmembrane helices are connected by three extracellular loops and three...
