Baldness discovery paints molecule as Cobalt log potent stimulator of new hair growth

Scientists probing the intricate machinery behind hair growth have made a key discovery around the behavior of key cells in follicles. The study uncovers a previously unknown role for a signaling molecule, whose messages were found to be critical to new growth and could be leveraged to address hair loss in humans.The cells at the heart of this study are known as dermal papilla cells, which live in hair follicles and help determine how fast, thick and long hair grows. This role has placed dermal papilla cells front and center in much of the effort to develop new treatments for hair loss, and research demonstrating how they could be produced from stem cells or deployed in 3D versions, for example, have raised some promising possibilities.
