The effect of cadmium on the bovine in vitro oocyte maturation and early embryo development [PDF]
, 2019 Common pollutants such as heavy metals and cadmium is among those with high environmental concerns. In vivo studies had shown that cadmium (Cd) causes oocyte degeneration and embryo mortality, and lowers pregnancy rates in mammals.

The Effect of Prolonged Culture of Chromosomally Abnormal Human Embryos on The Rate of Diploid Cells [PDF]
International Journal of Fertility and Sterility, 2016 Background A decrease in aneuploidy rate following a prolonged co-culture of human blastocysts has been reported. As co-culture is not routinely used in assisted reproductive technology, the present study aimed to evaluate the effect of the prolonged ...

In vitro production of bovine embryos derived from individual donors in the Corral® dish [PDF]
, 2017 Background: Since the identity of the embryo is of outmost importance during commercial in vitro embryo production, bovine oocytes and embryos have to be cultured strictly per donor.

Expression of connexins in human preimplantation embryos in vitro [PDF]
, 2004 Intercellular communication via gap junctions is required to coordinate developmental processes in the mammalian embryo. We have investigated if the connexin (Cx) isoforms known to form gap junctions in rodent preimplantation embryos are also expressed ...

Survival of bovine blastocysts produced in vitro and vitrified in vitri-tip and vitri-top devices. [PDF]
SPERMOVA, 2019 Vitrification is a new technique that has many potential advantages in mammalian oocytes and embryos. In the present work, the objective was to compare of post thawing survival rate by of blastocysts vitrified in vitro in two devices.

Embryo culture in presence of oviductal fluid induces DNA methylation changes in bovine blastocysts [PDF]
, 2017 During the transit through the oviduct, the early embryo initiates an extensive DNA methylation reprogramming of its genome. Given that these epigenetic modifications are susceptible to environmental factors, components present in the oviductal milieu ...
