Moreover, pan SIRT inhibition, siRNA-induced knockdown of Sirt3 in fertilised eggs, and the targeted ablation of Sirt3 in global knockout mouse models have each been shown to increase mitochondrial ROS production and repress blastulation and postimplantation development in mouse embryos generated via IVF [135].
Regarding the time of blastulation, it has been shown that the kinetics of bovine embryo development is affected by serum supplementation during IVM-IVF and embryo culture as the first and fourth cell cycles are prolonged by 4-5 hr in the absence of serum during IVM-IVF which in turn can influence the time of blastulation (12).
Blastulation rate included all embryos not transferred on day 3 that reached blastocyst stage; no significant difference between the two groups were noted.

The proportions of cleavage, blastulation, hatching of embryos out of the total treated oocytes and the proportions of post-thaw surviving and hatching out of the total cryopreserved embryos were subjected to are sin transformation and analyzed by one-way analysis of variance.
In these results, as in the studies with chlorpyrifos alone, sea urchin embryos were relatively insensitive during cleavage divisions and blastulation, but displayed high sensitivity at the mid-blastula 2 stage.
Cleavage and blastulation. A horizontal constriction, whose plan is perpendicular to the animal-vegetal axis, occurs 2 days after fertilization [ILLUSTRATION FOR FIGURE 3A OMITTED].
