Expression analyses of sox11b, sox19b, and max. In situ hybridization of sox11b (A), sox19b (B), and max (C) at 1-cell, sphere, and 24hpf stages. All three genes are maternally contributed, ubiquitously expressed at sphere stage, and expressed in the CNS at 24 hpf (A–C). (D–K) Animal pole view of GFP expression in Tg (miniCrestin:Gal4, UAS:GFP) embryos at shield stage. In control embryos at the shield stage (D) GFP expression is restricted to the dorsal domain. This domain is expanded in sox11b (E), sox19b (F) over-expressing and max deficient (G) embryos. The over-expression of max (H) represses transgene expression in the dEVL. Similar to max, snail1a deficient embryos exhibit expansion (I) whereas over-expressing snail1a embryos (J) show reduction in the dEVL domain. The dEVL remains expanded in cyc and max mRNA co-injected embryos (K) indicating that Nodal signalling is sufficient to regulate dEVL formation.
