Fig. 5. Fgf can induce prospective neural markers independent of antagonism of Bmp activity. Lateral views with dorsal towards the right (where dorsal is distinguishable) of late gastrula stage wild-type embryos and embryos overexpressing the RNAs indicated above the columns. Genes analysed by in situ hybridisation are indicated to the left of each row. The phenotypes of XFD-expressing embryos are similar to those of SU5402-treated embryos (Fig. 4) with vegetal sox3 expression reduced (A,B, arrowhead; C, asterisk) and animal expression shifted vegetally on the dorsal side of the embryo.
