Method for culturing hair follicle dermal sheath cells

Provided is a method for culturing hair follicle dermal sheath cells and progenitor cells thereof, which are effective cell materials for hair regeneration and the like by cell transplantation. In other words, hair follicular dermal root sheath cells are proliferated while maintaining their functions by culturing in animal cell culture medium supplemented with platelet-derived growth factor AA (PDGF-AA) and fibroblast growth factor 2 (FGF2) In addition, hair follicle dermal root sheath progenitor cells are differentiated and proliferated into dermal root sheath cells.
