Detailed explanation-1: -Dermal papilla, which is surrounded by the hair bulb (the enlarged part of hair follicle at the base), is a source of mesenchymal stem cells (MSCs) and essential growth factors required for hair growth and melanogenesis [51].
Detailed explanation-2: -The structure of a hair follicle. The hair follicle stem cells (red) are located in a niche created by the dermal sheath and dermal papilla cells (green). In anagen, the dermal papilla leads the down-growth from the secondary germ and bulge cells to the formation of the bulb.
