According to the information released, these cells are damaged with the passage of time and the advancement of age, hardening and making it more difficult for hair to grow. But with this new method, it would make it possible to “soften” said cells, favoring capillary development in a reversible way.
In contrast to other methods consisting of hair implantation -very common in Mexico and Turkey-, this way of combating alopecia is based on increasing the production of a tiny RNA called miR-205.
Through the genetic manipulation of stem cells responsible for the production of said RNA, it is possible to lower the degree of hardness of said cells, making it easier for hair to grow again. So far, and in the laboratory, the method has been successful in young mice and elderly rodents.
“[It could]grow hair in just 10 days,” Rui Yi, a pathology investigator at the Paul E. Steiner Research Center and a professor of dermatology at Northwestern University Feinberg School of Medicine, said in a statement released today. by The Spanish.
“Many times stem cells still exist, but they are incapable of generating hair,” adds Yi, referring to the fact that it is not a question of generating new stem cells, but of acting on the existing ones through said “smoothing.”
