Expression of Pax6 and Cdca7 at E14.5 in wild-type and Pax6 ^−/− telencephalon. In situ hybridizations on coronal sections. A, A′, B, B′ Pax6 expression declines sharply at the PSPB in wild-type telencephalon and more gradually in Pax6 ^−/− telencephalon. A′, B′ High magnification of areas outlined in A, B. C, C′, D, D′ Cdca7 expression declines sharply on the pallial side of the PSPB in wild-types but not in Pax6 ^−/− embryos. C′, D′ High magnification of areas outlined in C, D. Scale bars 50 µm
