Expression of foxl1, foxc1a, and foxc1b in wildtype zebrafish at 24 and 48 hpf. At 24 hpf, foxl1 is expressed at in the brain and trunk (A), similar to foxc1a (C), while foxc1b is observed in the ventral head/brain regions (E). At 48 hpf, all three forkhead genes are expressed in the pharyngeal arches (B,D,F). Scale bars are 500 µm.
