Study: New Way to Activate Stem Cells to Grow Hair
Researchers at the University of California, Los Angeles say in a study they have identified a new way to activate stem cells in hair follicles to regrow hair. The study, published today in Nature Cell Biology, findings could lead to new drugs that could promote hair growth for people with baldness or alopecia. The cells then either sent pyruvate to their mitochondria or convert it to lactate. Researchers blocked the production of lactate genetically in mice and found that this prevented hair follicle stem cell activation and then increased lactate production genetically in the mice, which accelerated hair follicle stem cell activation.
