The paper is titled, «Microenvironmental reprogramming by three - dimensional culture enables dermal papilla cells to induce de novo human hair follicle growth.» (sciencedaily.com)
But in a 3D culture, the cells form spheres that can coax new hair follicle growth -LRB- (sciencemag.org)
The group observed that, at the cellular level, one of the side effects of the diet was an expansion of hair follicle stem cells, leading to increasing hair follicle growth and retention rates. (sciencedaily.com)
