...-preimplantation gene activation (MGA). Moreover, expression of Hmgpi and Klf5 , which regulate Pou5f1 , Nanog and Cdx2 , was also significantly suppressed at zygotic gene activation (ZGA). Suppression of Hmgpi expression in Chd1 -knockdown embryos continued until the blastocyst stage, whereas suppression of Klf5...

... accessibility. This period of chick development takes place before egg-laying and encompasses several fundamental processes of avian embryology, including zygotic gene activation (ZGA) and blastoderm cell-layer increase. We have carried out morphological and cellular analyses of cleavage-stage chick embryos...
