23 citations,
July 2007 in “The journal of investigative dermatology/Journal of investigative dermatology” Hair follicle bulge cells don't help skin regrow after glucocorticoid damage; interfollicular epidermis cells do.
15 citations,
September 1999 in “British Journal of Dermatology” Epimorphin, a protein, plays a key role in the development of hair follicles in human fetuses, but it doesn't help in maintaining the stem cell population of the follicular skin layer.
129 citations,
May 2015 in “Cell Stem Cell” Different types of stem cells exist within individual skin layers, and they can adapt to damage, transplantation, or tumor growth. These cells are regulated by their environment and genetic factors. Tumor growth is driven by expanding, genetically altered cells, not long-lived mutant stem cells. There's evidence of cancer stem cells in skin tumors. Other cells, bacteria, and genetic factors help maintain balance and contribute to disease progression. A method for growing mini organs from single cells has been developed.
13 citations,
December 1983 in “Canadian journal of zoology” Heterotypic cell contacts likely help hair matrix cells differentiate during mouse hair follicle development.
