New research into factors that control the life and death of hair follicle cells could help people with baldness, as well as wound healing.Scientists have discovered that a single chemical is key to controlling when hair follicle cells divide, and when they die. This breakthrough could not only lead to effective treatment of baldness, but ultimately speed up wound healing because follicles are a source of stem cells.
“In real life, our new research gets us closer to understanding stem cell behavior, so that we can control it and promote wound healing,” Wang said. This research is detailed in an article that was recently published in theIn response to wounds, the liver and stomach regenerate themselves. However, Wang’s team of researchers studied hair follicles because they’re the only organ in humans that regenerates automatically and periodically, even without injury.
As with many chemicals, it is the amount that makes the difference in the outcome. If the cell produces a certain quantity of TGF-beta, it activates cell division. However, too much of it causes apoptosis. If researchers can determine more precisely the way TGF-beta activates cell division, and how the chemical communicates with other important genes, it might be possible to activate follicle stem cells and stimulate hair growth.
