Fig. 3

FGF signaling is required for mesoderm induction. Phenotypes of embryos at 43 hpf (A1-F1) and 73 hpf (A2-F2) after treatment with FGF signaling inhibitors (B1-D2) or bFGF protein (F1-F2) upon fertilization. Control embryos were treated with DMSO or 0.1% BSA. The concentrations of each drug or protein are indicated in each panel. All embryos are shown from a lateral view with mouth on the left. All panels have the same scale, with the scale bar marked in A1. Abbreviations: me: mesoderm; en: endoderm
