Figure 1

Endocardium (EC) (aqua blue line) forms the endocardial cushions (green circle) via cushion EMT (E9.5). Neural crest (NC) (pink circle) cells migrate into the OFT during E10.5-12.5. Valve leaflets undergoing differentiation (orange color) and maturation (purple color) (E13.5-18.5) are clearly indicated. Only one semilunar valve is shown. SV, semilunar valves; AV, atrioventricular canal; RV, right ventricle; LV, left ventricle
