Molecular signals from stem cells within the skin’s fatty layer trigger hair growth in mice, a finding that may lead to new treatments for baldness in people, researchers report. “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,” senior study author Valerie Horsley, an assistant professor of molecular, cellular and developmental biology at Yale University, said in a university news release.Details of the discovery appear in the Sept. 2 issue of the journal Cell.
