(A) Thin filament structure in control and Nup210 morphants was analyzed by phalloidin staining at different times of development.
(B) Tail muscle was stained for apoptotic death with an anti-activated caspase-3 antibody in control and Nup210-depleted animals.
(C) Cross-sections of zebrafish animals at 96 hpf were stained with the slow muscle marker F59 (green), phalloidin (red), and DAPI (blue) (n = 6–10 embryos).
Representative images of n ≥ 3 independent experiments. n = 10–20 embryos unless otherwise specified. Scale bars, 50 µm.
