Oxidative stress (OS) due to an imbalance between reactive oxygen species (ROS) and
antioxidants has been established as an important factor that can negatively affect the …

In a healthy body, ROS (reactive oxygen species) and antioxidants remain in balance. When
the balance is disrupted towards an overabundance of ROS, oxidative stress (OS) occurs …

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

Human embryonic stem (hES) cells are routinely cultured under atmospheric, 20% oxygen
tensions but are derived from embryos which reside in a 3–5% oxygen (hypoxic) …

Many factors affect development of mammalian preimplantation embryos in vitro. It is well
known that in vitro development of bovine embryos is highly affected by culture condition …

After in vitro maturation and fertilization of porcine oocytes, the fertilized embryos were
cultured under 5 or 20% oxygen (O2) for 7 days. In embryos cultured under 5% O2 versus …

Mouse embryos segregate three different lineages during preimplantation development:
trophoblast, epiblast and hypoblast. These differentiation processes are associated with …

A variety of evolutionary processes has led to the development of different organs to ensure
that internal fertilization occur successfully. Fallopian tubes are a particularly interesting …

Considerable advances in media development for the culture of preimplantation mammalian
embryos have been made since mouse embryos were first cultured and successfully …

The mitochondria, present in almost all eukaryotic cells, produce energy but also contribute
to many other essential cellular functions. One of the unique characteristics of the …
