A melanocyte is a type of cell that’s primarily located in the basal layer of the epidermis.

Abstract. I would like to stress that there seem to be three subpopulations of neural crest-derived melanocytes in the body that can be functionally and morphologically distinguished: the cutaneous melanocytes, which continuously synthesize small melanosomes to be transferred to keratinocytes; the uveal melanocytes, which synthesize larger …

Actually, recent data also show that aging …

Melanocytes in Development and Cancer – PMC

Normal Melanocyte Development. Melanocytes are derived from a group of highly migratory embryonic cells called the neural crest. The neural crest is induced at the time of gastrulation, in the zone between the neural and non-neural ectoderm (Erickson and Reedy, 1998), and gives rise to a number of cell types, including osteocytes, chondrocytes, and sensory neurons.

Melanocyte function and its control by melanocortin peptides

Melanocytes are cells of neural crest origin. In the human epidermis, they form a close association with keratinocytes via their dendrites. Melanocytes are well known for their role in skin pigmentation, and their ability to produce and distribute melanin has been studied extensively.

Basal Cells, Keratinocytes and Melanocytes – Medical News

Melanocytes are identified at the epidermal-dermal junction of the basement membrane. Melanin pigments which are synthesized provide different skin colors and also protect the skin from ultraviolet…

Melanocyte – an overview | ScienceDirect Topics

Melanocytes play a major role in protecting the skin from ultraviolet radiation through the production of melanosomes that are transferred to keratinocytes to protect their nuclei. Melanocytes are derived from neural crest and can be found within basal layer of the epidermis, the hair bulb, and the outer root sheath of hair follicles.

Melanocyte – an overview | ScienceDirect Topics

Melanocytes are found along the dermoepidermal junction as well as within hair follicles (Fig. I-3 ). They are responsible for the production and secretion of melanin pigment. Histologically the cells are characterized by small, dark, ovoid nuclei and scant, clear cytoplasm.

Neural Crest – Melanocyte Development – Embryology

melanocyte – (Greek, melanos = black) A pigmented cell, neural crest in origin, differentiating from melanoblasts located in the skin and other tissues that produces melanin. The melanocytes within the integument (skin) transfer melanin to keratinocytes to give skin colour and to the hair follicle to give hair colour.
