Through a process called melanogenesis, melanocytes produce melanin, which is a pigment found in the skin, eyes, hair, nasal cavity, and inner ear. This melanogenesis leads to a long-lasting pigmentation, which is in contrast to the pigmentation that originates from oxidation of already-existing melanin. There are … See more 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 See more • Chromatophore (the pigment cell type found in poikilotherm animals) • Eye color • Mole (skin marking) • Tanning activator • List of human cell types derived from the germ layers See more • Histology image: 07903loa – Histology Learning System at Boston University - "Eye: fovea, RPE" • Histology image: 08103loa – Histology Learning System at Boston University - "Integument: pigmented skin" See more In addition to their role as UV radical scavengers, melanocytes are also part of the immune system, and are considered to be immune cells. … See more • Melanoma - Cancer affecting melanocytes • Melanocytic tumors • Melanocytic tumors of uncertain malignant potential • Vitiligo - Decreased number of melanocytes due to autoimmune destruction causing decreased melanin See more • Ito S (June 2003).
