Analysis of cell death in sf3b1b460 mutants. (A-C) Double labeling with TUNEL (NBT/BCIP) and crestin whole-mount in situ hybridization (fast red). Transverse section is from the trunk region of a sf3b1b460 mutant, dorsal is up. (A) DIC image/TUNEL; (B) fluorescence image/crestin of the same section; (C) (A,B) merged. (D) Dorsal view of uninjected sf3b1b460 mutant at 16 hpf with TUNEL staining. (E) Dorsal view of zbcl2 mRNA injected sf3b1b460 mutant at 16 hpf with TUNEL staining. Reduced TUNEL staining is evident on the left side. (F) Lateral view of live uninjected sf3b1b460 mutant at 28 hpf. (G) Lateral view of live zbcl2 injected sf3b1b460 mutant at 28 hpf, showing less CNS cell death as compared with uninjected sf3b1b460 mutants but no melanophore rescue.
