Fig. 4. Co-expression of Xenopus regionalisation genes and LIM-hd genes in the same forebrain subdivisions. Horizontal sections through the telencephalon and the diencephalon of stage 32 embryos double labelled for x-Pax6 and x-Lhx5 (A) and x-Nkx2.1 and x-Lhx7 (B). For example, x-Nkx2.1 and x-Lhx7 are co-localised in the mge and hypothalamus but not in branchial arches (ba). tec, tectum. See Table 1 for abbreviations. Scale BAR=100 μm.
