melanocyte

 [mel´ah-no-sīt″, mĕ-lan´o-sīt]
any of the dendritic clear cells of the epidermis that synthesize tyrosinase and, within their melanosomes, the pigment melanin; the melanosomes are then transferred from melanocytes to keratinocytes. adj., adj melanocyt´ic.

mel·a·no·cyte

(mel'ă-nō-sīt),
A pigment-producing cell located in the basal layer of the epidermis with branching processes by means of which melanosomes are transferred to epidermal cells, resulting in pigmentation of the epidermis. It is also present in the basal layer of the epithelium of the oral cavity.
[melano- + G. kytos, cell]

melanocyte

/mel·a·no·cyte/ (mel´ah-no-sīt) (mĕ-lan´o-sīt) any of the dendritic clear cells of the epidermis that synthesize tyrosinase and, within their melanosomes, the pigment melanin; the melanosomes are then transferred from melanocytes to keratinocytes.melanocyt´ic

melanocyte

(mĕl′ə-nō-sīt′)
n.
An epidermal cell capable of synthesizing melanin.

melanocyte

[mel′ənōsīt′, məlen′ōsīt]
Etymology: Gk, melas + kytos, cell
a body cell capable of producing melanin. Melanocytes are distributed throughout the basal cell layer of the epidermis and form melanin pigment from tyrosine, an amino acid. Melanin granules are then transferred to adjacent basal cells and to hair. Melanocyte-stimulating hormone from the pituitary controls the amount of melanin produced.

Melanocyte

melanocyte

A specialised cell found at the dermal-epidermal junction—as well as the uvea, inner ear and meninges—which produces and stores melanin.

mel·a·no·cyte

(mel'ă-nō-sīt)
A pigment-producing cell located in the basal layer of the epidermis with branching processes by means of which melanosomes are transferred to epidermal cells, resulting in pigmentation of the epidermis.

melanocyte

A pigment cell of the skin. A cell carrying MELANIN or capable of producing melanin.

melanophore

or

melanocyte

a type of pigment cell (or CHROMATOPHORE) that contains the pigment melanin, usually found in the skin of animals. It has a protective or camouflage function.

melanocyte

A pigment-bearing cell. It is found in the iris, the choroid, the retina, the sclera, the skin, etc. See melanin; choroidal naevus; iris naevus.

melanocyte

any of the dendritic clear cells of the epidermis that synthesize tyrosinase and, within their melanosomes, the pigment melanin; the melanosomes are then transferred from melanocytes to keratinocytes.

melanocyte-stimulating hormone (MSH)
a peptide from the anterior pituitary which influences the formation or deposition of melanin in the body, especially in amphibians and fish.
