ON THE COVER
Whole mount of mouse tail epidermis stained for integrin α3β1 (red). Linage tracing of hair bulge stem cells with induced deletion of integrin α3β1 (GFP-positive cells) demonstrates that these cells stay confined within their niche and contribute to the formation of hair follicles 4 weeks after the deletion was induced.
