WebMelanocytes are a heterogeneous group of cells found in different locations in a human body. They consist of the central body and dendrites. Melanocytes originate from melanoblasts, neural pluripotent cells of neural crest. Dermal melanocytes derive from several populations of neural crest cells, including cranial, dorsal and ventral trunks.
