The biology of melanocyte and melanocyte stem cell.
The melanocyte stem cells of the hair follicle provide an attractive system for the study of the stem cells. Successful regeneration of a functional organ relies on the organized and timely orchestration of molecular events among distinct stem/progenitor cell populations. The stem cells are regulated by communication with their specialized microenvironment known as the niche. Despite remarkable...
متن کاملThe Melanocyte Model
The effect of various agents that cause metaphase arrest in dividing cells was studied on the rapid reversible darkening of frog skin under the influence of melanocyte-stimulating hormone (MSH). Darkening is due to dispersion of melanin granules in melanocytes and is thought to be accompanied by a gel-to-sol cytoplasmic transformation. After subsequent washing the skin lightens, with aggregatio...
متن کاملMelanocyte stem cells∗
Pigmentation of mammalian hairs is mediated by specialized pigment-producing cells referred as melanocytes. Hair pigmentation is tightly linked with hair regeneration cycles, where melanocytes proliferate and differentiate during the hair growth phase, but depleted by apoptosis during the regression phase. This periodical appearance of melanocytes is maintained by a small pool of immature stem ...
متن کاملY2-Melanocyte-Stimulating Hormone
Peptides of the pro-opiocortin class produce pronounced cardiovascular and natriuretic actions. We have investigated the acute cardiovascular effects of one of the most potent members of this class, y2-melanocyte stimulating hormone (y2-MSH), in rats. Pressor actions of y2MSH administered systemicaMy were eliminated by ganglionic blockade with chlorisondamine. Peripheral cholinergic blockade fa...
متن کاملMacrophage-melanocyte Heterokaryons
High yields of mouse macrophage-melanocyte heterokaryons and macrophage-macrophage homokaryons were obtained through the virus-induced fusion of cells spread on a glass surface. After fusion there was a striking reorganization of cellular architecture by means of a colcemid-sensitive process. Heterokaryons were isolated through the use of differential trypsinization and many underwent division ...
