Stem-Cells May Be Answer To Baldness

Balding people may be able to beat the horror of the smooth-scalp-look by seeking 21st century science. According to
scientists, Alopecia (hair loss) could be treated with stem cells from the root of a hair. The cells could also be
multifariously applicable.
Stem cells from hair forming follicles could be developed into neurons, observed scientists, when they planted the cells
under the skin of mice. The follicles are a source for stem cells which could also serve as a treatment of nervous
diseases.
Hair building follicles run through a cycle of growth and dormancy phases. Therefore the supply with fresh cells is
necessary. These cells deliver stem cells, which lie in a bulge collateral of the follicle. Robert Hoffman and
colleagues from the University of California have recently shown that these stem cells also build a protein which is
characteristic for nerve forming stem cells.
Now the researchers have analysed the changeableness of the follicle stem cells. They extracted the cells from follicles
at the base of mice whiskers. One week after they had been transplanted under the skin of donor animals, the stem cells
developed into neurons. After several weeks they formed skin cells, smooth muscle cells and so called melanocytes, in
which skin pigments are produced.
“These results indicate that hair follicles can be used as easily accessible source for stem cells”, report the
researchers in the magazine “Proceedings of the National Academy of Sciences”. Stem cells could produce replacement
tissue in the future which can be implanted to patients whose tissue has stalled or cannot perform its tasks. For the
extraction of adult stem cells such as those form the follicles, it’s not necessary – in contrast to an embryonic
extraction – to produce and then destroy embryos.
