Fig. 3. VegT and Nodal signaling act at long-range to affect FoxI1e expression in the animal cap.

(A) In situ hybridization in VegT-depleted and CerS-injected embryos shows FoxI1e is most upregulated in the animal cap rather than the vegetal mass at stage 10. Dorsal is the to the right in the bisected uninjected embryo. The VegT and CerS embryos did not dorsal axes. (B) Vegetal masses stripped of all mesoderm contamination dissected from control and CerS-injected embryos confirm that the vast majority of increase in FoxI1e expression is derived from non-endodermal tissue. Scale bars represent 200 μm.
