Fig. 4 The effects of Sox3dNLS require Wnt/β-catenin signalling. (A-G) Ectopic activation of boz, sqt, gsc and chd by Sox3dNLS RNA injected at the 1- to 2-cell stage and assayed at 4.5 hpf (B, compare with uninjected WT embryo, A) was blocked by WT Sox3 (C), but also by dnTcf3 (D,E) or a β-catenin 2 MO (F,G). Animal pole views, dorsal right. Scale bar: ∼200 μm.
