Stem cells have been big news for the past couple of years and yet they remain remarkably inscrutable in terms of declaring their true nature and identity. On p. 778–784 of this issue, Toma et al. describe the identification of a new type of stem cell from the dermis of the skin, called SKP cells. These can be converted into several differentiated cell types in vitro, including neurons, and might become a source of cells for therapeutic tissue repair.
