Annotation of TF expression in the CRTFN in the E11.5 cortex. (A) Schema of sagittal view of E11.5 mouse brain. The pallium is in four shades of purple corresponding to regional subdivisions (LVP: laterovental pallium, RVP: rostrovental pallium, CDP: caudodoral pallium, MP: medial pallium). (B–D) ISH analysis of Meis2 (B), Dmrt3 (C), and Id3 (D). (E) Heatmap of cortical expression levels (0 to 5: pink to red scale) of CRTFN TFs in the four pallial subdivisions. ★ indicates that the TF also has VD gradient. ✚ indicates that the TF also has DV gradient. o indicates that the TF also has MP expression.
