pouC regulates myocardial specification in the AVC. A: Representative in situ hybridization analysis performed on control and pouC morphant zebrafish at 48 hpf. B: Same as in (A) at 72 hpf. C: Zebrafish embryos were injected with control or pouC MO, and in situ hybridization analysis was performed at 24 hpf using the indicated probes. D: Schematic summary of marker analysis, demonstrating a specific defect in AVC cardiomyocyte specification in pouCmorphant embryos. anf, atrial natriuretic factor; amhc, atrial myosin heavy chain; vmhc, ventricular myosin heavy chain. Cardiac borders outlined with dotted lines, and arrowheads indicate region of AVC.
