Fig. 2. Three-dimensional reconstruction of the zebrafish otic vesicle (72 hpf)
generated from confocal images. (A) The otic vesicle of the
wild-type zebrafish has well-formed epithelial pillars (EP) that shape the
semicircular canals. The anterior cristae (AC), lateral cristae (LC) and
anterior maculae (AM) are indicated. (B) The otic vesicle of an
eya4 morphant fish is smaller and misshapened, with fused epithelial
pillars and malformed semicircular canals.
