Abstract
A method for culture of hair follicular dermal sheath cells or precursor cells thereof which are potent cellular materials for such as hair regeneration by cell transplantation is provided. That is, by performing culture in an animal cell culture medium supplemented with platelet-derived growth factor AA (PDGF-AA) and fibroblast growth factor 2 (FGF2), hair follicular dermal sheath cells are proliferated while sustaining their function, or hair follicular dermal sheath precursor cells are differentiated into dermal sheath cells and proliferated.
