Adult mammalian tissues are maintained by multipotent stem cells, many of which are highly responsive to soluble Wnt proteins. A new study reports the requirement of two Tcf family members, Tcf3 and Tcf4, in the development and maintenance of epithelial stem cells in skin through Wnt-dependent and -independent processes.
