mortality/aging
• arrest at ~E9.5 with heart formation but no somites

embryo
• arrest at ~E9.5
• do not show somites at ~E9.5

cellular
• at E9.0, only rare and single centrioles are found in mitotic poles in 11% of cells compared to wild-type where each pole of a mitotic spindle contains a pair of centrioles
• increase in the fraction of mitotic cells (10% compared to 5% in wild-type embryos)
