Fig. S5 Induction of Tg(ins:GFP) Expression in smo Mutants Is Coincidental with Close Contact with Wildtype Endodermal Cells
(A and B) Transverse confocal images of smo mutant host stained for GFP (green; A and B) and β-catenin (white; A) at 18 hpf. Wildtype donor cells are labeled with rhodamine dextran (red). ([A] and [B]) show the same embryo. (A) During the transplantation experiments shown in Figure S4 and Table S1B, we found one embryo in which Tg(ins:GFP) expression in smo mutant endoderm was rescued (arrow) when wildtype donor cells were incorporated into the endoderm directly adjacent to the rescued Tg(ins:GFP) expressing mutant cell. (B) Magnified view of the rescued Tg(ins:GFP) expressing mutant cell (arrow) shown in (A).
