Feeder-free Derivation of Melanocytes from Human - JoVE

First of all, you should know that melanin is a pigment, the main function is to determine the color of your skin. However, a lack or excess of this component in our body can lead to skin problems and other issues related to the hair or eyes. 2 The melanocytes (melanin) are present in the bottom layer of our epidermis (skin). Melanocytes originate in the neural crest during embryonic development. They migrate to the skin, inner ear, eye, and the lower part of the brainstem, called the medulla oblongata. The skin contains about 10 times more keratinocytes (i.e. cells that produce keratin protein), but each melanocyte functions enough to pigment 30 keratinocytes.

Melanocytes migrate to the epidermis from the neural crest during embryonic development. Melanocytes are dendritic cells. The main function of melanocytes is to produce melanin. Melanocytes and melanin in the skin are shown in figure 2. Melanocyte definition is - an epidermal cell that produces melanin. THE concept that high-level melanocytes (Langerhans cells) are effete, except in a melanogenic sense, has required modification since our previously reported demonstration of adenosine Transcription factors specifically expressed by melanocytes and by melanoma cells (especially MITF) regulate the expression and function of many of those pigment-specific factors.

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.

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. In response to ultraviolet (UV) radiation its production by the skin and pituitary is enhanced, and this plays a key role in producing coloured pigmentation found in the skin, hair and eyes. Function Acting through melanocortin 1 receptor, α-MSH stimulates the production and release of melanin (a process referred to as melanogenesis) by melanocytes in skin and hair. Acting in the hypothalamus, α-MSH suppresses appetite. α-MSH secreted in the hypothalamus also contributes to sexual arousal.
