Fig. 5.

LiCl dose-dependent expansion of endoderm and mesoderm territories. FISH of pairs of transcripts shown in top right in NaCl (control)-treated (A,B), and in embryos treated with medium (C,D) or high (E,F) doses of LiCl. (G) Gene expression patterns in late blastulae treated with increasing doses of LiCl. (H) Confocal image of β-catenin:GFP in high LiCl-treated late blastula showing extensive expansion of nuclear β-catenin. All embryos are shown at the late blastula stage in the lateral view.
