This figure shows Dbx1 expression in adjacent sections to the images shown in Fig. 3. These images were used for measurements of the hem and the dorsal telencephalic neuroepithelium, taken upto the ventral extent of Dbx1 in adjacent sections in CreERT2; Lhx2 lox/lox (dashed lines, B,D,F) and CreER;Lhx2 lox/lox ;Pax6 lox/lox (H,J,L) embryos. Dbx1 expression in the control brain is not shown. Scale bar is 200 Îźm. (JPEG 856 kb
