The development of in-vitro matured and microfertilized horse oocytes was examined in
vitro. Fertilized oocytes were produced by 20-h insemination of in-vitro matured and partially …

To improve our understanding of the molecular mechanisms underlying early embryo
development, further characterization of gene activity in oocytes and embryos is urgently …

With the advent of Assisted Reproductive Technologies, our understanding of the
reproductive system in both men and women has progressed in an exponential manner …

Although the culture requirements and the metabolic profile of the preimplantation embryo
have been thoroughly investigated since their first successful culture in a defined medium …

Rat 1-cell embryos, recovered from naturally mated females, were cultured in a chemically
defined medium (mR1ECM). When examined after 24, 56, 64 and 80h of culture, embryos …

After compaction, the preimplantation mouse embryo switches to a glucose-based
metabolism, whereas for the 2-to 4-cell stage embryo, glucose can be inhibitory. In this …

The metabolism of glutamine and glucose, separately and in combination, by the sheep
conceptus recovered on Days 2, 6, 13, 15, 17, and 19 of pregnancy was assessed over 2.5 …

Preimplantation mouse embryos become arrested after first or second cleavage when
cultured in hypoxanthine-supplemented Whitten's medium. We present evidence that the …
