Human skin-derived epidermal melanocytes are the true architects of skin pigmentation—are specialized cells responsible for melanin production, which defines skin color and protects against UV radiation damage. Found in the basal layer of the epidermis and hair follicles, these cells transfer melanin to keratinocytes, forming a natural barrier against harmful Ultraviolet (UV)radiation. Originating from neural crest cells, they are regulated by key proteins like tyrosinase (TYR) and MITF. In addition to Skin Pigmentation, they also play roles in immune responses. Due to their critical functions, human skin derived epidermal melanocytes are central to research on pigmentation disorders, melanoma, and skin regeneration therapies.
