<P> 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 . Once synthesized , melanin is contained in special organelles called melanosomes which can be transported to nearby keratinocytes to induce pigmentation . Functionally , melanin serves as protection against UV radiation . Melanocytes also have a role in the immune system . </P>
