Fig.1. In toto analysis of x-Dll3, x-Nkx2.1, x-Emx1, x-Pax6 and x-Eomes expression in Xenopus brain. Whole-mount dissected brains at stage 32 (left column, entire brain) and stage 35 (right column, focused on the forebrain) are photographed in lateral views. In all panels, anterior is left and dorsal is up. The arrowhead in (A,C,E,G,I) indicates the position of the psb between the pallium (pa) and the subpallium (spa). The asterisk in (B) points to the x-Dll3 negative area in the rostral forebrain, see text. The inset indicates the plan of sections for transverse (t) and horizontal (h) sections in the next figures, as deduced from the axis of the brain. This antero-posterior axis is indicated by black arrows. Therefore, in the telencephalon, a horizontal section is parallel to the axis and allows the visualisation of transverse boundaries and divisions. Abbreviations are in Table 1. Scale BAR=100 μm.
