Whole-mount in situ hybridization of GrnA knockdown embryos. Expression patterns of the marker genes insulin (A and B), trypsin (C and D), fabp2 (O and P), and fox3A at 72 hpf, cebpb at 96 hpf (E–H), dlx3b at 8 hpf (I and J), myod at 54 hpf, and hand2 at 30 hpf (K–N), were examined using WISH in the controls (Ctrl) and grnA morphants. C–F and K–N, dorsal views, anterior up; A, B, G, H O, and P, lateral views, anterior left).
