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.
- It should come as no surprise that people with darker skin
have more active melanocytes compared to people with lighter skin.
- While melanocytes produce, store, and release
melanin, keratinocytes are the largest recipients of this pigment.
- 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.
- Melanocyte-stimulating hormone (MSH)- stimulates the production and release of melanin by melanocytes in skin and hair; also affects appetite and sexual arousal.
- 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 will 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.
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.
