Squamous cells: These are flat cells in the upper (outer) part of the epidermis, which are constantly shed as new ones form. Basal cells: These cells are in the lower part of the epidermis, called the basal cell layer. These cells constantly divide to form new cells to replace the squamous cells that wear off the skin’s surface. As these cells move up in the epidermis, they get flatter, eventually becoming squamous cells. Melanocytes: These are the cells that can become melanoma. They normally...
Thinking of "ABCDE" can help you remember what to look for: ; Border that is irregular: The edges are often ragged, notched, or blurred in outline. The pigment may spread into the surrounding skin. ; Color that is uneven: Shades of black, brown, and tan may be present. Areas of white, gray, red, pink, or blue may also be seen. ; Evolving: The mole has changed over the past few weeks or months.
Primary human epidermal melanocytes isolated from neonatal foreskin, cryopreserved at the end of the secondary culture. These cells are isolated from darkly pigmented tissue. Viability at lea
In the human skin, melanocytes are present in the epidermis and hair follicles. The basic features of these cells are the ability to melanin production and the origin from neural crest cells. This...
What is melanin? Melanin is a naturally occurring substance or pigment produced by special skin cells called melanocytes that are found in one's skin, hair follicles, eyes and other parts...
Your hair. The innermost layer of your skin. Your pupils and irises. The substantia nigra and locus coeruleus (areas of your brain). The medulla and zona reticularis (areas of your adrenal gland). The stria vascularis of your cochlear duct (part of your inner ear).
Only 20-30% of melanomas are found in existing moles. ; While 70-80% arise on normal-looking skin.
Melanin is a pigment made by specialized cells in the skin called melanocytes . The amount and type of melanin determines skin color. 1 Human skin is highly variable around the world...

Everyone knows and seems to agree that melanocytes are there to generate melanin - an intriguing, but underestimated multipurpose molecule that is capable of doing far more than providing pigment a...
