Oxidative stress is involved in the aetiology of defective embryo development. Reactive
oxygen species (ROS) may originate from embryo metabolism and/or embryo surroundings …

BACKGROUND Mitochondria are multitasking organelles involved in ATP synthesis,
reactive oxygen species (ROS) production, calcium signalling and apoptosis; and …

We evaluated the in vitro development of porcine zygotes that were cultured in a novel
culture medium, porcine zygote medium (PZM), under different conditions and compared to …

Contents While much is known about the metabolism of exogenous nutrients such as
glucose, lactate, pyruvate, amino acids by oocytes and pre‐implantation mammalian …

In human in-vitro fertilization (IVF) embryos are routinely transferred to the uterus on day 2 or
day 3 of development. Resultant implantation and pregnancy rates are disappointingly low …

The function that cumulus cells play during oocyte maturation ie, in keeping the oocyte
under arrest, in participating in the induction of meiotic resumption and in supporting …

Oocytes of all mammals contain an endogenous lipid reserve. This feature reflects their
shared ancestral origin, the yolk-rich amniote egg. However, the lipid is species-specific in …

Along with the transition from maternal to embryonic genome control the mammalian
preimplantation embryo undergoes significant changes in its physiology during …

Mitochondria, originally of bacterial origin, are highly dynamic organelles that have evolved
a symbiotic relationship within eukaryotic cells. Mitochondria undergo dynamic, stage …

This study was an investigation of metabolism during bovine preimplantation development
from the oocyte up to the hatched blastocyst derived in vitro or in vivo. Metabolism was …
