Histological analysis of Dlx gene expression patterns during tooth development. Transversal sections of hybridized lower jaws of 4 cm to 5.5 cm long embryos illustrating the expression patterns of Dlx3 (A-D), Dlx4 (E-H), Dlx5 (I-L) and Dlx1 (M-P) during the development of oral teeth. Lower jaws of 4 cm long embryos (A, I and M), 4.3 cm (E), 4.5 cm (B, F, and J), 4.6 cm (G, N and O), 5 cm (C, D and K), 5.1 cm (P), 5.4 cm (H) and 5.5 cm (L). We illustrate only the late LM stage when Dlx genes are predominantly expressed in the mesenchyme of tooth buds. Legends are as in Figure 2 and 4. Scale bar: 25 μm.
