Melanocyte - Wikipedia
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.

Melanocyte is a highly differentiated cell that produces a pigment melanin inside melanosomes. This cell is dark and dendritic in shape. Melanin production is the basic function of melanocyte. With the process of differentiation this cell loses the proliferative potential.
Melanocyte | Pigmentation, Skin Color, Melanin | Britannica
Melanocyte, specialized skin cell that produces the protective skin-darkening pigment melanin. Birds and mammals possess these pigment cells, which are found mainly in the epidermis, though they occur elsewhere—e.g., in the matrix of the hair.

2023年5月1日 · Eumelanin and pheomelanin are produced in various amounts in the basal layer of the epidermis within cells called melanocytes. Melanocytes are the mature forms of melanoblasts, which migrate from the neural crest following neural tube closure.
Signaling Pathways in Melanogenesis - PMC
Melanocytes are melanin-producing cells found in skin, hair follicles, eyes, inner ear, bones, heart and brain of humans. They arise from pluripotent neural crest cells and differentiate in response to a complex network of interacting regulatory pathways. Melanins are pigment molecules that are endogenously synthesized by melanocytes.
Biology of melanocytes in mammals - PMC - PubMed Central (PMC)
Melanocytes mainly produce two types of melanin: eumelanin and pheomelanin. Eumelanin is dark brown and is the primary pigment for protection against ultraviolet radiation (UVR). In contrast, pheomelanin is reddish-yellow and is more susceptible to UVR-induced damage.

2007年2月21日 · Melanocytes can absorb ultraviolet radiation (UVR) and survive considerable genotoxic stress. The skin is the main barrier to the external environment, and relies on melanocytes to provide,...
Melanocytes, Melanin, and More - Tempo Bioscience
2016年7月10日 · Melanocytes produce and store melanin in organelles called melanosomes in response to MSH secretion. The process by which melanin is created is called melanogenesis. The biochemical pathways of melanogenesis that result in melanin production involves a cascade of protein activations driven by phosphorylation. The pigment is then transferred ...

2024年8月1日 · Melanin is produced by cells called melanocytes. Melanin helps determine the color and tone of skin, hair, and eyes. Melanin also helps protect against UV damage, and plays a role in vision, hearing, and immune system function.
Melanocyte - an overview | ScienceDirect Topics
Melanocytes are specialized cells that produce melanin pigments responsible for skin, hair, and eye pigmentation. The synthesis and storage of melanin occurs in unique lysosome-related organelles called melanosomes, which regulate melanin production via …
