Fig. 9. Absence of tfap2a activity leads to increased levels of apoptosis
in cranial neural crest. (A,B) Dorsal view of wild-type (A) and
mobm610 (B) flat-mounted embryos at 26 hpf following TUNEL
assay staining. Black arrowheads indicate the anterior and posterior extent of
the otic vesicle. (C,D) Detection of dying cells by Acridine Orange staining
of wild-type (C) and mobm610 mutant (D) embryos at 25 hpf
(lateral views). White arrowheads indicate increased levels of apoptosis. ov,
