Melanocytes are melanin -producing neural crest -derived cells located in the bottom layer (the stratum basale) of the skin's epidermis, the middle layer of the eye (the uvea ), the inner ear, vaginal epithelium, meninges, bones, and heart. Melanin is a dark pigment primarily responsible for skin color. Melanocyte, specialized skin cell that produces the protective skin-darkening pigment melanin. Birds and mammals possess these pigment cells, which are found mainly in the epidermis, though they occur elsewhere—e.g., in the matrix of the hair. Melanocytes are branched, or dendritic, and their 2021-01-19 · Melanocytes are cells that produce melanin, a dark pigment responsible for the coloration of hair and skin.

Melanosomes Cytocrine. Dark vs.
They migrate during embryological development and localize in the epidermis and hair follicles where they pigment skin and hair (Nishimura, 2011). Melanocytes and their production of melanin pigment (a process termed melanogenesis) have important roles in cutaneous physiology (Hearing, 2011). The most
Melanocytes are a type of neural crest-derived cells in the body , most commonly found in the stratum basale, the bottom layer of the epidermis of the skin, eyes , and to a lesser known degree, the meninges (membrane around the brain), the heart and the inner ear . Melanocytes are present throughout the nail unit, including the matrix, nail bed, and hyponychium.
