Set the ball rolling. Human skin cells grown on a flat culture remain dispersed and unable to induce the formation of hair follicles (left). But in a 3D culture, the cells form spheres that can coax new hair follicle growth (right).
Scientists have successfully grown new hair follicles from the skin cells of balding men. While the research team hasn’t yet shown whether the structures, which produce strands of hair on our bodies, are fully functional and usable for transplants onto a scalp, experts say the discovery is a significant step toward finding new treatments for hair loss.
