New method of treating baldness
Researchers from Yale University in the United States have discovered the source of signs that promote hair follicle regeneration, stimulate hair growth, and form new hairs.
This is an important finding, which can lead to new treatments that are more effective for people with baldness.
In an article published in the American Journal of Cell Science on September 2, scientists identified stem cells under the fat layer of human skin and showed that molecular markers From these cells is really necessary to promote hair growth in mice.
New hope for bald people.
' If we can use subcutaneous fat cells to replace, stimulate stem cells, promote hair follicle regeneration, we can help hair grow again' , alerie Horsley, assistant Physics and molecular biology professor, and also the main author of the article said.
Horsley's team observed that when hair falls, the layer of fat in the scalp shrinks. When hair grows back, the fat layer extends in a process called adipogenesis . The team also found that a type of stem cell involved in the creation of new fat cells, precursor fat cells, is needed to reproduce hair in mice.
They also found these cells produce molecules called PDGF (one of the growth factors, or proteins that regulate cell growth and division). In particular, it plays an important role in the formation of blood vessels (vessels), which are also needed to stimulate hair growth.
Horsley's lab is trying to identify other signals produced by fat cells, which play an important role in regulating hair growth. The research was funded by the National Institutes of Health and the Connecticut Stem Cell Research Program of the United States.
