Fig. 4.

The expression pattern of the atrophin2 gene. Whole-mount in situ hybridization was conducted with a 3′ probe at various developmental stages. (A and B) Labeling of the germ band is apparent in a dorsal (A) or a lateral view (B) of the late gastrula. (C) At 24 hpf, essentially all tissue except the yolk is labeled. (D) Labeling diminishes from the caudal extreme by 36 hpf. (E) Arrowheads highlight the labeling of the otic vesicles in a dorsal view of a larva at 36 hpf. (Scale bar: 100 μm.)
