Ngn2 rescues the formation of tangentially migrating interneurons in the cerebral cortex. Frontal sections through the telencephalon of E15.5 embryos hybridized with RNA probes for markers of tangentially migrating interneurons. Interneurons expressing Dlx1 (A–A") and GAD67 (B–B") are born in the ventral telencephalon and migrate tangentially into the cortex. Many of these neurons are missing in absence of Mash1 (A‘, B‘), and are rescued in Mash1^KINgn2 embryos (A", B"). Outlined areas are magnified in the insets.
