Migration and compaction defects in pdlim7 MO2 injected embryos. A-R: Whole-mount antisense RNA in situ hybridization of wild-type and MO2 injected embryos. tbx5 (A-H) expression at 24 hpf (A-D) and 28 hpf (E-H) in wild-type (A, C, E, G) and MO2 injected (B, D, F, H) embryos. G and H magnified lateral view of pectoral fin. fgf10 (I-L) expression at 28 hpf in wild-type (I, K) and MO2 injected (J, L) embryos. K and L magnified lateral view of pectoral fin. Expression at 24 hpf in wild-type and MO2 injected embryos of fgf24 (M-N), hand2 (O-P), and fgfr2 (Q-R), respectively. Head is positioned to the left.
