Schematic diagram of the distribution and main markers of epidermal SCs. iSCs are clustered and interspersed in the basal layer of epidermis. Most of the hair follicular SCs reside in the bulge. The isthmus SCs localize in the junction between the hair follicle and sebaceous glands. The upper part of the isthmus contains infundibular SCs. Sebaceous gland duct SCs are located at the opening of the glands while sebaceous gland SCs are located in the glands. Each population of epidermal SCs expresses distinct markers, which are shown in the colored boxes
