Hedgehog signaling has a key role in hair follicle development, as well as in induction of the most common cancer in individuals of European descent, basal cell carcinoma (BCC). A new study shows that BCCs strongly resemble embryonic hair follicles and that BCC induction requires active Wnt/β-catenin signaling.
