Background Embryonic genome activation (EGA) is certainly a critical event for the preimplantation embryo, which is manifested by changes in chromatin structure, transcriptional machinery, expression of embryonic genes, and degradation of maternal transcripts. morulae and blastocysts. On the other hand, transcript levels of SMARCAL1 decreased throughout preimplantation development. Summary The high levels of structural conservation… Continue reading Background Embryonic genome activation (EGA) is certainly a critical event for
