Comparisons of embryogenesis (A–E) and nuclear cleavage (F–J) among WT (A,F), MZslbp2Δ4−/− (B,G), MZslbp1Δ1−/− (C,H), slbp2 transgenic MZslbp2Δ4−/− embryos (D,I), and H2B-GFP transgenic MZslbp2Δ4−/− embryos (E,J). In vitro transcribed H2B-GFP mRNAs were injected into the one-cell embryos to visualize the dynamic nuclear cleavage (F–J). The developmental stages of embryos are marked at the top.
