Cell proliferation arrest and apoptosis triggered in the absence of γ-TuSC formation. A. Zebrafish control and morphant embryos treated through the BrdU incorporation procedure. Embryos (8 hpf) were exposed to a BrdU pulse for 1 h, then fixed and treated for DNA labeling with DAPI (red) and immunolabeled for the incorporated BrdU (green). tubg1-Mo embryos did not incorporate BrdU in their DNA, indicating proliferation arrest. B. Apoptotic response revealed by TUNEL assay in embryos (8 hpf). The tubg1-morphant showed many clusters of cells positive for TUNEL stain (arrowheads) distributed throughout the blastoderm.
