Human hair follicle-derived mesenchymal stem cells: Isolation, expansion, and differentiation

Figure 1 Schematic of the human hair follicle. An intact hair follicle usually includes the inner root sheath, outer root sheath, and connective tissue sheath (dermal sheath). The human hair follicle mesenchymal stem cells lie within the dermal papilla or dermal sheath (connective tissue sheath) of the hair follicle. Citation: Kiani MT, Higgins CA, Almquist BD.
