Stem cells for mammalian skin are thought to reside in the hair follicles, where a stem cell niche harbors its residents until the time comes to initiate new hair growth or to regenerate skin. Tumbar et al. develop a strategy to highlight the slowly dividing skin cells likely to represent such epithelial stem cells. Further analysis into the transcriptional profile of these cells reveals suites of proteins dedicated to reading the environment in preparation for stem cell activation.
