Abstract

Although previous reports suggested that canonical Wnt signaling has opposing effects on epidermal and hair follicle stem cells, two recent papers (Choi et al., 2013; Lim et al., 2013) now show that Wnt signaling promotes proliferation in both stem cell populations, revealing new insights into regeneration of both skin compartments.
