Fig. 6. Relationship between Cs-ZicL, ß-catenin, and Cs-FoxD. (A) Control embryos at the 32-cell stage showing Cs-ZicL expression in two pairs of A-line cells (arrowheads) and two pairs of B-line cells (arrows). Scale bar represents 100 µm. (B) Cadherin-overexpressing embryos at the 32-cell stage, showing Cs-ZicL expression in the two pairs of B-line cells (arrows), but not in the two pairs of A-line cells. (C) Cs-ZicL expression is found only in the two pairs of B-line cells in the 32-cell stage embryos developed from eggs injected with Cs-FoxD morpholino. Scale bar represents 100 µm. (D) Ectopic Cs-ZicL expression in many cells in the 32-cell stage embryos developed from eggs injected with Cs-FoxD mRNA.
