Baldness: a "guardian" protein could stop or reverse hair loss

A research team identified a protein that plays a protective role essential to the functioning of hair follicle stem cells (HFSC) and would act as a powerful regulator of apoptosis, so that when its rate decreases, HFSCs, overworked, no longer produce new hair. Regulation of this pathway could potentially reverse the process and treat or prevent baldness and alopecia. Mammal hair follicles are an excellent model for the study of structure [...] …
