Gene expression in the diencephalon during ZLI formation. (A-F) In situ hybridisation was used to analyse the expression of Shh (blue in (A, D); red in (C, E)), Lfng (blue in (B, E; red in (F)) and Wnt8b to stage HH14 (A, B), HH15 (C), HH18.5 (D) and HH22 (E, F) chick embryos. Whole heads are shown in (A-D) and hemisected brains in (E, F) (anterior to the left, dorsal to the top). Note expression of Shh and Wnt8b in the ZLI (yellow arrowheads in (B, D-F)).
