Figure 3. Molecular marker analysis of genetic cooperation between Nkx2.5 and Mef2c.
Whole mount preparations of E9.5 wild-type (A-C), Nkx2.5−/− (D-F), Mef2c−/− (G-I) and Nkx2.5−/−;Mef2c−/− (J-L) embryos shown in right (A, D, G, J) and left lateral (B, E, H, K) and frontal (C, F, I, L) views. Arrowheads denote the outflow tract. Roman numerals denote first through fourth pharyngeal arches. a, atria; h, heart; lv, left ventricle; oft, outflow tract; rv, right ventricle; v, ventricle; ss, somite stage.
