Fig. 7. Schematic presentation of the neural structures of cdx1a/4
morphant, and Fgf and/or RA signal-defected cdx1a/4 morphant
embryos. (A) Wild type (wt). (B) cdx1a/4 morphants.
(C) cdx1a/4 morphants that received co-injected
fgf3/8MOs. (D) cdx1a/4 morphants treated with 300
µmol/l SU5402. (E) cdx1a/4 morphant embryos expressing the
raldh2MO (see Fig. S4 in the supplementary material). (F)
cdx1a/4 morphant embryos treated with 50 µmol/l DEAB. (G)
cdx1a/4 morphant embryos treated with SU5402 and DEAB.
