(Submitter supplied) Metabolic stress associated with negative energy balance in high producing dairy cattle and obesity in women is a risk factor for decreased fertility. Non-esterified fatty acids (NEFA) are involved in this pathogenesis as they jeopardize oocyte and embryo development. Growing evidence indicates that maternal metabolic disorders can disturb epigenetic programming, and more specifically DNA methylation, in the offspring. more...

(Submitter supplied) There is an inevitable need for combining in vitro and in vivo culture systems during specific developmental time points to facilitate a comprehensive understanding of early embryo development which would yield insights into the molecular pathways controlling early development and to improve our knowledge in regulation of embryonic development. In current study, we aimed to understand the influences of in vitro culture conditions on bovine blastocyst originated in vivo at 2- or 8-cell stagre. more...

(Submitter supplied) we induced an energetic stress on in vitro embryos to observe the epigenetic response associated with metabolic stress. Embryos were created with slaughterhouse cows oocytes and then exposed to an elevated glucose concentration (5mM vs 0.2mM for the control embryos) for the first 3 days post fecundation and then cultivated in normal media until blastocyst stage. Blastocysts were collected from 4 different weeks of culture. more...

(Submitter supplied) Assisted reproduction technologies (ART) and high selection pressure observed in the dairy industry are leading towards the use of younger females for reproduction purpose, reducing the interval between generations. This situation might have an impact on embryo quality, which can affect the success rate of the procedures. This study aims to document the effect of donor age on embryo quality, on transcriptomic level, in order to caracterize the effect of using young animals for reproduction purpose.
