Abstract
Hair Today, Skin Tomorrow: The epidermis of mammals contains hair follicles, sebaceous glands, and interfollicular epidermis, but it has not been clear how the development and repair of these structures is regulated. Snippert et al. (p. 1385 ) show that a stem-cell cluster in the hair follicle, characterized by the expression of Lgr6, a close homolog of the Lgr5 marker for stem cells in the small intestine and colon, resides directly above the hair bulge and gives rise to all cell lineages of the skin. Skin wounds in adult mice are repaired by Lgr6 stem cells in the hair follicles that flank the damage. After hair morphogenesis, Lgr6 stem cells give rise to epidermal and sebaceous gland lineages to generate fully differentiated new skin.Keywords
