Drastic reduction in EnMT in ErgΔEx4/ΔEx4 during valve morphogenesis. (A-F) Hearts of ErgΔEx4/+ (A,C,E) and ErgΔEx4/ΔEx4 (B,D,F) mouse embryos at E10.5 stained for β-galactosidase and sagittally sectioned. The AVC and OFT mesenchymal cells that form normally in control embryonic hearts (C,E) are drastically reduced in the mutant (D,F). AVC, atrioventricular canal; OFT, outflow tract; A, atrium; V, ventricle.
