From Zygote to Implantation: Morphological and Molecular Dynamics during Embryo Development in the Pig

Abstract excerpt

The increasing focus on the pig as a biomedical model calls for studies which investigate morphological and molecular mechanisms during initial embryonic development in this species. In the pig, the paternal genome is actively demethylated in the zygote, whereas the maternal genome remains methylated. The major genome activation occurs at the four-cell stage, when prominent ribosome-synthesizing nucleoli develop...
