Nuclear and cytoplasmic localization of interferon-tau in in vitro-produced bovine blastocysts.

O-11: Diverse Effects of Polyunsaturated Fatty Acids on Oocyte Maturation and Development In vitro

Background: Polyunsaturated fatty acids (PUFAs) have been shown to influence fertility and endocrinology of reproduction and metabolic activity in many species. In dairy cows, we and others have shown changes in steroid and metabolic hormones and prostaglandins leading to alteration of ovarian activity and uterine function. These can influence fertility by changes in folliculogenesis cyclicity ...

The effects of activated-omental extract on nuclear and cytoplasmic in vitro maturation of rat oocytes

Objective: The role of growth factors, including vascular endothelial growth factor of activated omentum on mitosis is clearly known, though not on all the aspects of in vitro oocyte maturation. This study was designed to assess the effect of activated-omental extract (AOE) on in vitro maturation (IVM) of rat cumulus-oocyte complexes (COCs). Materials and Methods: In this experimental study, th...

Successful cryopreservation of in vitro derived bovine blastocysts in microcapillary pipette tips

The open pulled straw has been used effectively to vitrify preimplantation embryos because of geometricfeatures that allow rapid rates of temperature exchange. One possible inexpensive alternative to the openpulled straw are commercially-available microcapillary pipette tips commonly used for electrophoresis. Themain purpose of this study was to compare the survival rates of in vitro produced b...
