Fig. 1. Branchial arch expression patterns of the genes downregulated in Dlx5/6−/−.
Lateral views (A–L) or frontal views (M–X) of wild-type and Dlx5/6−/− E10.5 mouse embryos processed by whole-mount in situ hybridization. Arrows and arrowheads indicate changes in gene expression in mdBA1 and BA2, respectively.
