Fig. 4. Xsix3 represses epidermal fate but requires Xotx2 for the induction of neural markers in animal caps. Animal caps from control uninjected embryos (Control) or embryos injected with either Xsix3, Xotx2, or a mixture of the two RNAs, as indicated at the top, were dissected at stage 9, cultured to stage 14 and analysed for the expression of the genes indicated to the left. The column to the right (Embryo) shows expression of the analysed genes in control embryos.
