Germ layer of origin of melanocyte
WebMelanoblasts are precursor cells of melanocytes, that arise from neural crest in vertebrates and through several cycles of migration and proliferation, they populate the basal layer … WebMelanocytes are dendritic, pigment-synthesizing cells of neural crest origin with clear cytoplasm confined to the basal layer. The ratio of melanocytes to basal cells ranges from 1:4 on thecheek to 1:10 on the limbs. The function of melanocytes is to produce protective melanin pigment.
