Fig. S1. — FKO and Pax3-Cre driven Utx phenotypes. (A) WT or FKO hearts were dissected at P2 and sectioned. Interventricular septum (IVS) appeared normal in FKO mice (n = 3/3). (B) Male Utx^fl/y, Pax3-Cre mice demonstrate shortened snouts, narrow palpebral fissures, and a dome-shaped forehead. (C) Utx^fl/y, Pax3-Cre mice are viable; however, female Utx^fl/fl, Pax3-Cre mice die at birth and are not recovered at weaning (χ² *P < 0.01). (D) Utx^fl/fl, Pax3-Cre lungs fail to inflate at birth (n = 3) and float in PBS.
