In the News – Scientists Find Hair Growth Molecule in Mice

Snippet from the article:

The study identifies a key signaling molecule that tells hair follicles to start the hair-growing cycle.

“These are very complex molecular signals, and the authors have very nicely shown that there is one molecule, laminins 511, that is a very important signal to tell the hair molecule to move through the process. It’s part of a basic biological understanding,” said Dr. Ronald Crystal, chairman of genetic medicine at New York Presbyterian Weill Cornell Medical Center in New York City.

The researchers, reporting in the Aug. 1 issue of Genes & Development, feel the findings may one day hold the key to treating male-pattern baldness, as well as hair loss from chemotherapy or even to restore hair on burn victims.

But, as so often happens, the study was conducted in mice and, as Crystal pointed out, “Mice are not just little men and women. They are different than us and also different in their hair.”

This is a terrific story which shows an important step to the process of hair growth. Could it explain why some men of one race have no body hair and others get much? Following that thread of thinking can be fun. Could it be that genetic balding is caused by a mutation on that particular gene?
