Fig. 6. Cross- and autoregulatory mechanisms monitor expression levels of dlx3 and dlx7. Whole-mount in situ hybridization with (A,E,I,M) wild-type, (B,F,J,N) dlx7 MO, (C,G,K,O) dlx3 MO and (D,H,L,P) dlx3+7 MO embryos. (A-D) dlx3 and (E-F) dlx7 expression at 6 somites, dorsal views, anterior towards the left. (I-P) dlx3 expression at 21 somites. (I-L) Lateral views with anterior towards the left, (M-P) dorsoanterior views with anterior towards the top. ot, otic region; olf, olfactory region; va, visceral arches. Scale bar: 100 µm.
