A collection of cutting-edge methods to analyze and manipulate epidermal cellprecursors and mature epidermal cells. These protocols cover different methods and models for culturing epidermal cells, for enriching very early epidermal progenitors, and for studying epidermal cell commitment and differentiation both in vitro and in vivo. Topics of special interest include the derivation, characterization, and utility of epidermal stem cells, mature epidermal cells and their characterization, and applications in regenerative medicine. These rea
