Cardiac outflow tract phenotype in Minoxidil-treated Tbx1neo2/lacZ fetuses (E16.5-E17.5). a-a'') H&E stained histological sections of a WT heart as reference. b-e) Examples of hearts from Minoxidil-treated Tbx1neo2/lacZ fetuses. f) the incidence of septation defects (one OFT valve vs. two OFT valves) in Minoxidil-treated individuals is significantly lower than in vehicle-treated individuals (Chi-square test). IVS: Interventricular septum; LV: Left ventricle; RV: Right ventricle; VSD: Ventricular septal defect; PTA: Patent truncus arteriosus; IncTA: Incomplete septation of the arterial trunk; Ao: Aorta; P: Pulmonary trunk; DORV: Double outlet right ventricle. Scale bare: 100 μm.
