Pectoral fin mesenchymal gene expression in Pdlim7 knock-down embryos. Dorsal view of whole-mount antisense RNA in situ hybridization of wild-type (A, C, E, G, I, K, M, O, Q, S) and MO2 injected (B, D, F, H, J, L, N, P, R, T) embryos. A-D: tbx5 expression in wild-type and MO2 injected embryos at 36 hpf (A-B) and 48 hpf (C-D). E-H: fgf10 expression at 36 hpf (E-F) and 48 hpf (G-H). I-L: hand2 expression at 28 hpf (I-J) and 48 hpf (K-L). M-P: shh expression at 28 hpf (M-N) and 48 hpf (O-P). Q-T: msxc expression at 28 hpf (Q-R) and 48 hpf (S-T). Head is positioned to the left.
