Coaxing hair growth in aging hair follicle stem cells

Scientists discovered how to soften hair follicle stem cells to enable them to grow hair again. These cells stiffen with age and produce less hair. In a study in mice, the investigators report that they can soften the stem cells by boosting the production of a tiny RNA, miR-205, that relaxes the hardness of the cells. When scientists genetically manipulated the stem cells to produce more miR-205, it promoted hair growth in young and old mice.
