Examples of melanocyte in the following topics:
- Vitiligo is a disorder characterized by patchy loss of skin pigmentation due to the immune system attacking melanocytes in the skin.
- Vitiligo is a disorder characterized by patchy loss of skin pigmentation due to the immune system attacking melanocytes, the melanin-producing cells of the skin .
- Variations in genes that are part of the immune system or part of melanocytes have both been associated with vitiligo.
- Another technique transplants melanocytes to vitiligo affected areas, effectively repigmenting the region.
- Skin color is determined largely by the amount of melanin pigment produced by melanocytes in the skin.
- In this layer lie important cells called melanocytes.
- Melanocytes are
irregularly shaped cells that produce and store a pigment called melanin.
- People with darker skin
have more active melanocytes compared to people with lighter skin.
- The transfer of melanin from melanocytes to
keratinocytes occurs thanks to the long tentacles each melanocyte extends to
upwards of 40 keratinocytes.
- Individuals with albinism posses melanocytes, the melanin-producing cell of the skin, but their melanocytes are unable to produce melanin.
- The average square inch (6.5 cm²) of skin holds 650 sweat glands, 20 blood vessels, 60,000 melanocytes, and more than 1,000 nerve endings Fig .
- Skin Structure.Skin has mesodermal cells, pigmentation, or melanin provided by melanocytes, which absorb some of the potentially dangerous ultraviolet radiation (UV) in sunlight.
- This portion of the nail does not have any melanocytes, or melanin-producing cells.
- The nail bed contains the blood vessels, nerves, and melanocytes, or melanin-producing cells.
- Melanoblasts that form melanocytes migrate with neural crests cells to the epithelium and begin producing melanin prior to birth.
- Neural crest cells are a transient, multipotent, migratory cell population unique to vertebrates that gives rise to a diverse cell lineage including melanocytes, craniofacial cartilage and bone, smooth muscle, peripheral and enteric neurons and glia.
- This happens because a lack of sympathetic stimulation in childhood interferes with melanin pigmentation of the melanocytes of the iris.
- Our skin also contains melanocytes that produce a pigment
layer also contains melanocytes, the cells that are largely responsible for
determining the color of our skin and protecting our skin from the harmful
effects of UV radiation.
