melanocytes
n. (plural of melanocyte English)
Usage examples of "melanocytes".
Anyway, basically, what a lab is going to be looking for is whether that hyperpigmentation is intracellular, as in melanocytes, which are the dark, pigmented cells that are much more concentrated in non-Caucasians, or intercellular.
For some years it was assumed that nothing like intermedin existed in mammals, but in 1955 biochemists at the University of Oregon were able to isolate from the mammalian pituitary a hormone that stimulated the activity of the melanocytes (mel'uh-noh-sites), which are the cells that produce the skin pigment melanin.
