Are we close to finding a cure for male baldness?
In their study, published in PLOS Biology, the team succeeded in getting the macrophages to activate the stem cells in hair follicles on non-inflamed skin. The discovery was actually found by chance, when researchers realized that mice given anti-inflammatory drugs had the curious side effect of hair regrowth. Dr. Mirna Perex-Moreno, one of the researchers involved in the project, wondered if the hair growth was connected to the body’s immune reaction, and it turned out that she was right. Although macrophages are cells from the immune system which mainly help to fight infection and wound repair, it also seems that they play a role in activating the skin's stem cells
