Stoffel and coworkers report that stearoyl-CoA desaturase 1 (SCD1)-deficiency in mice inhibits palmitoleoylation of Wnt3a, impairing epidermal barrier function, hair growth, and sebaceous gland development. Application of an artificial lipid barrier effectively reverses hair growth cycle arrest in these mice, but it does not support sebaceous gland development. For details and other findings, see the article on page 1424.
