Embryo morphokinetics suggests that the timing of the first embryonic cell divisions may
predict the developmental potential of an embryo; however, correlations between embryonic …

The time-lapse system is a non-invasive method that enables a continuous evaluation
through embryo development. Here, we examined the association between the …

The embryonic developmental block occurs at the 8-cell stage in cattle and is characterized
by a lengthening of the cell cycle and an increased number of embryos that stop …

Summer heat stress is a major cause of reduced development of preimplantation embryos.
Nevertheless, seasonal effects on embryo morphokinetics have been less studied. We used …

In cattle, pregnancy loss due to early embryonic mortality is a major concern that significantly
impacts reproductive efficiency. Given the economic importance of cattle in livestock …

STUDY QUESTION What is the relationship between cleavage stage embryo kinetics,
blastocyst metabolism and subsequent embryo viability? SUMMARY ANSWER Embryos …

Metabolism and epigenetics, which reciprocally regulate each other in different cell types,
are fundamental aspects of cellular adaptation to the environment. Evidence in cancer and …

To understand the compromised survival of embryos derived from assisted reproductive
techniques, transcriptome survey of early embryonic development has shown the impact of …

Embryonic development is initially controlled by maternal RNAs and proteins stored in the
oocyte, until gene products gradually generated by the embryo itself take over. Major …

Mammalian embryos that rapidly reach the two‐cell stage in culture have a higher
probability of becoming viable blastocysts. Our goal was to separate two‐cell bovine …
