Abnormalities associated with melanocytes are often caused by disruptions to or loss of function of the pigmentation and its related factors. These pigmentary disorders are classified as hyperpigmentation disorder, hypopigmentation disorder, mixed hyperpigmentation disorder and mixed hypopigmentation disorder which are further subclassified into acquired and congenital [50] .

Melanoma, also known as malignant melanoma, is a type of cancer that develops from the pigment-producing cells known as melanocytes.[1] Melanomas 

However, accumulating evidence has shown that melanocytes are also active factors in the skin immune system, participate in immune responses, and • Function of cutaneous melanocytes: is to synthesize melanin in membrane‐bound oragnelles called melanosomes & to transfer melanosomes to neighboring keratinocytes to provide protection from UV irradiation. • Function of otic , ocular & meningeal melanocytes. 2002-02-01 · Melanocytes are cells of neural crest origin.

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.

Melanocyte-stimulating hormone describes a group of hormones produced by the pituitary gland, hypothalamus and skin cells. It is important for protecting the skin from UV rays, development of pigmentation and control of appetite. melanocytes: Skin cells derived from the neural crest that produce the protein pigment melanin. Mentioned in: Malignant Melanoma , Skin Pigmentation Disorders In vitiligo patients, melanocytes in the basal layer of unaffected zone epidermis are 25% less compared with healthy control, and melanocytes detachment from the basal layer into the upper layer has also been observed, which is termed as “transepidermal loss”. 84 The results described herein concur to delineate a pathogenetic scenario that melanocyte detach from the basal layer was Melanocytes are essential for skin homeostasis and protection, and their defects in humans lead to a wide array of diseases that are potentially extremely severe. To date, the analysis of molecular mechanisms and the function of human melanocytes have been limited because of the difficulties in accessing large numbers of cells with the specific phenotypes.

Become a member and A melanocyte is a type of cell that's primarily located in the basal layer of the epidermis. Melanocytes produce melanin, a brown pigment that is responsible for skin coloration and protecting against the harmful effects of UV light. Melanocytes are also present in the hair and in the irises of the eyes.

Melanocytes are also present in the hair and in the irises of the eyes. Ed Reschke / Photolibrary / Getty Images 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.

First of all, you should know that melanin is a pigment, the main function is to determine the color of your skin.
