Impaired PME formation and progression resulted in aberrant forebrain formation. (A, D, G) Phenotype comparison of uninjected (A), vsx1 tbMO injected (D) and vsx1 tbMO and dkk1 mRNA coinjected embryos (G) at 8-10 somite stage. Brackets show the distance between head and tail. Note that the forebrain formation is restored with a shortened AP axis and anterior neural plate marker is expressed in more posterior positions in vsx1 tbMO and dkk1 mRNA coinjected embryos. (B-C′, E-F′, H, H′) Whole-mount in situ hybridization of anterior neuroectoderm marker rx3 and PME marker hgg1 at bud stage. (B, C, E, F, H) Dorsal-animal views with anterior to the top. (B′, C′, E′, F′, H′) Lateral views with animal to the top. (I) Proportion of brain phenotypes in different experiments at 24 hpf. The injected reagents and their amounts are indicated at the bottom. Numbers of examined embryos are indicated at the top.
