Abstract Background Oocyte secreted factors (OSFs), including growth differentiation factor 9
(GDF9) and bone morphogenetic protein 15 (BMP15), play an important role in the process …

Global cattle genetic market is experiencing a change of strategy, large genetic companies,
traditionally recognized in the artificial insemination field, have also begun to operate in the …

In order to achieve fertilization sperm cells, first need to successfully interact with the zona
pellucida. To this end, the sperm surface is extensively remodeled during capacitation and …

The present study examined the effect of coculturing cumulus oocyte complexes (COCs) and
denuded oocytes (DOs) during in vitro maturation (IVM) on nuclear and cytoplasmic …

The mechanism of fertilization remains largely enigmatic in mammals. Most studies
exploring the molecular mechanism underlying fertilization have been restricted to a single …

Low pregnancy rates during the summer are due, in part, to reduced fertilization. Given that
elevated temperature is associated with this season, we investigated the effect of heat stress …

It has previously been demonstrated that zona pellucida imaging of human oocytes using
polarized light microscopy is a clinically applicable method for the noninvasive assessment …

Adequate nutrition is required for maintenance of normal reproduction in cattle. Albumin, the
best marker and fundamental part of nutrition, most abundant plasma protein and major …

The aim of this study was to determine the effects of different exposure lenght to heat shock
(HS) during in vitro maturation (IVM) on zona pellucida (ZP) ultrastructure and …

The ubiquitin-proteasome system regulates many cellular processes through rapid
proteasomal degradation of ubiquitin-tagged proteins. Ubiquitin C-terminal hydrolase-L1 …
