Fig. 1

Increased endodermal specification does not rescue endodermal cell migration in toddler;lefty2 double mutants.

(A) Representative images of embryos analyzed in B and D. In situ hybridization with a sox17 probe at 75% epiboly; dorsal to the right. Endoderm in toddler;lefty2 double mutants resembles toddler single mutants. (B) The number of lateral endodermal cells is increased in toddler;lefty2 double mutants compared to wild-type and toddler single mutant embryos. Each point represents a single embryo. Red bars are averages. p-Values for pairwise comparison with wild type unless otherwise noted. **p<0.001; unpaired two-tailed t-test. N = number of independent experiments; n = number of embryos. (C) Schematic representation of experimental measurements shown in B and D. The locations of lateral endodermal cells in individual embryos are measured relative to the AP-VP axis and then consolidated across embryos. (D) Measurement of frequency with which cells were found at a given location in an embryo of a certain genotype. A cell at the animal pole corresponds to 100% embryo height, while a cell at the vegetal pole corresponds to 0%. AP = Animal pole; VP = vegetal pole. The same embryos were measured in B and D.
