Whole mount views of Dlx gene expression during caudal primary scale and tooth development. In situ hybridizations against Dlx1 (A-B), Dlx2 (C-D), Dlx3 (E-F), Dlx4 (G-H) and Dlx5 (I-J) mRNAs. Left lateral view of tails from embryos at stage 30 (A, C, E, G and I), anterior to the left, dorsal to the top. Four dorsal scale buds and three ventral buds are stained in A, five dorsal and four ventral scale buds in C, E, G and I. Dorsal views of lower jaws (B, D, F, H and J), anterior to the top, from 4.9 cm (B and D), 4.5 cm (F), 4.6 cm (H) and 4.7 cm (J) long embryos. Scale bars: 200 μm, s: symphysis.
