Oocytes and preimplantation embryos require careful regulation of the redox environment
for optimal development both in vivo and in vitro. Reactive oxygen species (ROS) are …

The cryopreservation of embryos of most domestic species has become a routine procedure
in embryo transfer, and recently, advances have been made in the cold storage of …

Based on the premise that superovulation in cattle is optimal when superstimulation is
initiated at the time of follicular wave emergence, the present study was done in beef heifers …

We have designed, built, and tested microfluidic systems capable of transporting individual,
preimplantation mouse embryos (100-/spl mu/mm to 150-/spl mu/m diameter) through a …

The purpose of this study was to assess the viability of ovine embryos after replacing fetal
calf serum (FCS) with polyvinyl alcohol (PVA) in vitrification and warming solutions. Ovine …

The in vivo survival rate of rabbit morulae after vitrification in a mixture of dimethyl
sulphoxide and ethylene glycol solution without protein supplement (WPS) was compared …

When using embryo transfer (ET), sperm and oocytes are potential sources of pathogens
(bacteria, viruses, prions). Additionally, contamination may result from environmental …

The objectives of this study were to determine the surface tension of bovine follicular fluid
(BFF) and TCM-199, and the effects of the synthetic surfactant, Twin-80, or FCS, in TCM-199 …

Biological products like serum and BSA are routinely used in embryo freezing solutions.
These products are undefined and can potentially expose the embryos to infectious agents …

This study evaluates a new synthetic substitute (CRYO3, Ref. 5617, Stem Alpha, France) for
animal-based products in bovine embryo cryopreservation solutions. During the experiment …
