A Arrest and death of early blastomeres during the first four cleavage cycles. Maximum intensity z-projections of optical serial sections of embryos examined at day 4. Many embryos show large early blastomeres that are arrested at interphase (asterisks) or prophase (arrow heads) or already show clear signs of cell death: DAPI staining reveals variably sized and irregularly shaped clumps of highly condensed chromatin (large arrows). Notably, frequent findings are remnants of mitotic chromosome structures (small arrows).
The embryos were fixed and mounted on coverslips in such a way that the three-dimensional structure was maintained. DNA staining with DAPI is shown in white, f-actin filaments (phalloidin-TRITC) in orange. Scale bars represent 100 µm (overviews) or 10 µm (details).
