Fig. S3 (A and B) Expression of cmlc2 in dorsal views at 24 hpf as determined by in situ hybridization (purple) in whole-mount embryos indicates that cardiac progenitors are similarly specified in WT control (A) and 138-morpholino-injected fish (B). (C–F) In situ hybridization for cspg2 (C and D) and notch1b (E and F) in wild-type (C and E) and miR-138scr fish (D and F) demonstrate atrioventricular-specific expression at 48 hpf. a, atrium; ht, heart progenitors; v, ventricle.
