Figure Lengend Snippet: a, IHC of RORB (green), BHLHE22 (red) and VGLUT2 (blue) in coronal sections of PD 7 mouse brains from control and Meis2 cKO mice. b, Quantification of fluorescence intensity across cortical bins (lateral Bin1 to medial Bin10; Bin1–2, AI; Bin3–4, SSp; Bin5–8, MOs/p; Bin9–10, mPFC). In Meis2 cKO mice, RORB-, BHLHE22- and VGLUT2-positive signals expand into MC areas. c,d, IHC of VGLUT2 in coronal sections of control and Meis2 cKO mice at PCD 16 and PD 0, spanning the rostro–caudal cortical axis. Scale bars, see images; statistical details, see Methods.
