Pluripotent stem cells (PSCs), including embryonic and induced pluripotent stem cells (iPSCs), show atypical cell cycle regulation characterized by a high proliferation rate and a shorter G1 phase compared with somatic cells. The mechanisms by which somatic cells remodel their cell cycle to achieve the high proliferation rate of PSCs during reprogramming are unclear. Here we identify that the I...
this study investigated the effect of different harvesting techniques on the recovery rate and quality of bovine cumulus oocyte complexes (cocs) and their subsequent developmental competence including in vitro maturation, fertilization and blastocyst formation. the cocs were retrieved from slaughter ovaries using aspiration, slicing, or aspiration followed by slicing. the cocs were examined mic...
Fertilization is followed by complex changes in cytoplasmic composition and extensive chromatin reprogramming which results in the abundant activation of totipotent embryonic genome at embryonic genome activation (EGA). While chromatin reprogramming has been widely studied in several species, only a handful of reports characterize changing transcriptome profiles and resulting metabolic changes ...
