The oviduct and uterus provide the environments for the earliest stages of mammalian
embryo development. However, little is known about the mechanisms that underlie the …

The testes are essential endocrine regulators of fetal masculinization and male development
and are, themselves, subject to hormonal regulation during gestation. This review focuses …

The purpose of this work is to address the relationship between transcriptional profile of
embryos and the pregnancy success based on gene expression analysis of blastocyst …

The detrimental effects of heat stress on fertility in cattle are less pronounced in heat-tolerant
breeds. Although these genetic differences reflect differences in thermoregulation, cells from …

The aim of this study was to compare the transcriptome of the oviductal isthmus of pregnant
heifers with that of cyclic heifers as well as to investigate spatial differences between the …

Parthenotes may represent an alternate ethical source of stem cells, once biological
differences between parthenotes and embryos can be understood. In this study, we …

The early embryo's nutritional environment plays an important role in establishing its
developmental potential. However, little is known about the specific nutrient requirements of …

In vitro production of livestock embryos is important for both agriculture and biomedical
research. In spite advances in designing media and culture systems, we do not yet know …

Glucose plays a fundamental role during oogenesis and embryogenesis, satisfying the
metabolic demands of oocytes and embryos, providing for stored energy reserves in the …

La producción de embriones in vitro (PIV) es una biotecnología reproductiva que impacta
los siste-mas ganaderos favoreciendo el mejoramiento ge-nético y que también se ha …
