In a recent Yale study, researchers have found that signals from stem cells within skin’s fatty layer may spur hair growth in mice, promoting a possible new treatment for baldness in men and women.
According to the study’s senior author Valerie Horsley, an assistant professor of molecular, cellular and developmental biology at Yale University, she noted in a recent press release, “If we can get these fat cells in the skin to talk to the dormant stem cells at the base of the hair follicles, we might be able to get hair to grow again.”
For men battling male pattern baldness, stem cells remain in their hair follicle roots; however, they lose the ability to stimulate hair growth. These stem cells need signals from within the skin for hair to grow but where to find the signals has been a mystery.
According to the Yale study, researchers discovered that after hair dies, the layer of fat in the scalp that comprises most of the skin’s thickness shrinks; however, as hair growth begins, this fat layer will expand.
In this study using mice, researchers found their hair regeneration required a type of stem cell involved in the creation of new skin fat cells and that these cells produced the molecules required to produce hair growth. Once these imperfect mice received injections of stem cells from healthy mice, hair follicles began to grow.
Previously, studies on men have with bald parts of their scalp have disclosed they have the same number of hair stem cells as hairy areas. With these injections, scientists found that an 86 percent kick start in hair growth. However, the question now is whether or not these stem cell injections can work on humans and stimulate hair growth.
Additional studies will need to take place and it could take quite some time to determine its effect on humans but this is good news for those suffering with baldness.
The report was recently disclosed in the September issue of the journal, Cell.

According to a new study by Roland Lauster, a professor at the Berlin Technical University in Berlin, Germany, he’s been able to regrow hair follicles from stem cells. Researchers are alleging that cells may be implanted onto the scalp and dead follicles can be rejuvenated.
Unfortunately for interested parties, you’re going to have to wait. Lauster conducted studies on mice and believes that humans will have this opportunity in maybe five years. He thinks this baldness cure could help as many as 80 percent of the people who suffer from hair loss.
This isn’t the first time these findings have come to light. In an article by Fox News, it states that the University of Pennsylvania found similar findings in 2004 but it didn’t produce a cure for baldness.
