Fig. 1. dlx3 and dlx7 are co-expressed by the same otic and olfactory cells. (A,B) Whole-mount RNA in situ hybridization with probes for (A) dlx3 and (B) dlx7 at 18 somites. Lateral views, anterior towards the left. (C,D) Flat-mount double in situ hybridization showing (C) olfactory and (D) otic expression of dlx3 and dlx7 at 18 somites. dlx3 expression is shown in red in both panels with dlx7 expression shown in purple. Anterior is towards the top. ot, otic vesicle; olf, olfactory placode; va, visceral arches. Scale bars: in A, 100 µm for A,B; in C, 25 µm for C,D.
