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 2014-12-29 · Melanocytes possess several functions besides a role in pigment synthesis, but detailed characteristics of the cells are still unclear. We used whole transcriptome sequencing (RNA-Seq) to assess differential gene expression of cultivated normal human melanocytes with respect to keratinocytes, fibroblasts and whole skin. This study expands understanding of opsin 3 (OPN3) function and of skin pigmentation. The findings presented here reveal that the nonvisual OPN3 modulates the pigmentation of human epidermal melanocytes—the melanin-producing cells of the skin—by controlling the activity of the main pigmentation receptor, melanocortin 1 receptor (MC1R). Abnormalities associated with melanocytes are often caused by disruptions to or loss of function of the pigmentation and its related factors.

Pigments that determine human skin colors include melanin, hemoglobin (red), hemosiderin (brown), carotene (yellow), and bilin Among those, melanins play key roles in determining human skin (and hair) pigmentation. classified into two major types based on their biosynthetic pathways, as updated and reviewed elsewhere: eumelanin (dark brown most studied function of melanocytes is to synthesize melanin that confers color on skin and hair, and protects epidermal cells from ultraviolet radiation-induced changes in DNA structure (Plonka et al., 2009). However, accumulating evidence has shown that melanocytes are also active factors in the skin immune system, participate in immune Melanocyte-stimulating hormone is a collective name for a group of peptide hormones produced by the skin, pituitary gland and hypothalamus.
