Fig. S3
Ppp4cb knockdown or overexpression has little effect on Wnt target gene expression, related to Figure 3. One-cell stage embryos were injected with 1 ng ppp4cb-MO1 (bMO1) or 100 pg ppp4cb mRNA and examined by whole-mount in situ hybridization for the expression of boz at the sphere stage and vent at the shield stage. boz is a direct target of maternal Wnt signaling and vent is a target of zygotic Wnt signaling. Note that both of them were not markedly affected in down- or up-regulation of ppp4cb. Upper panel, lateral views with dorsal to the right; lower panel, animal-pole views with dorsal to the right. The ratio indicated at the right corner was the number of embryos with the phenotype shown/the number of observed embryos.
