Each of these cells divides into two cells: One that replaces itself and another that differentiates into a pigment-producing daughter cell called a melanocyte, which imbues hair with its browns, reds and blacks.
Melanoma is a [[cancer]] that originates from a '' melanocyte '' ([[melanin]] - producing skin cell), and is associated with over exposure to the [[sun]] or [[UV]] [[radiation]].
As a new hair grows, some melanocyte stem cells become melanocytes, which give the strand its color, while others remain stem cells and store pigment for the next generation of hair.
More of their melanocyte stem cells matured into color-producing melanocytes, depleting the store of stem cells.
Toki Color from Lane Labs has been shown to support melanocyte production, which is responsible for forming pigment in the hair color.
I can watch a string of neural crest cells in a zebrafish crawl out of the dorsal midline and stream over generally predictable paths to their destinations, but the actions of an individual melanocyte, for instance, are variable and beautiful to see.
Her doctors never located the original, or primary, tumor, but laboratory tests eventually confirmed that all the trouble started in a pigmented cell, or melanocyte, in the skin.
The hormone was named melanocyte-stimulating, hormone, in perfectly straightforward fashion, a name usually abbreviated as MSH.
Melanoma is often a type of skin cancer, but it can also develop in the eye, digestive tract, brain or spinal cord, or any place where melanocyte cells are found, according to the
Because melanosomes-mini-organs that actually do the work of making pigment inside of melanocyte cells-can survive for millions of years as part of a fossil.
