Fig. 6 sox9 genes are expressed in rhombomere centres under control of FGF-receptor signalling. (A-D) Expression of sox9a (A,B) and sox9b (C,D) RNA at 24 hpf (A), 30 hpf (B,D) and 20 hpf (C). Arrowheads indicate r4. (E-L) Wild-type embryos were either treated with DMSO (E,G,I,K) or treated with SU5402 at 20 hpf (F,H) and at 30 hpf (J,L) and analysed for sox9a (E,F,I,J) and sox9b (G,H,K,L) RNA expression at 36 hpf. Embryos were double labelled for ephA4 (red: E-H) RNA to mark r3 and r5. Arrowheads indicate ventromedial r4 (I,K). All embryos are shown with anterior to the left in dorsal (A-H) or lateral (I-L) view. Scale bars: 50 μm.
