Functional role of GATA3 and CDX2 in lineage specification during bovine early embryonic development.

ABSTRACT:

In brief

The lineage specification during early embryonic development in cattle remains largely elusive. The present study determines the effects of trophectoderm-associated factors GATA3 and CDX2 on lineage specification during bovine early embryonic development.

Abstract

Current understandings of the initiation of the trophectoderm (TE) program during mammalian embryonic development lack evidence of how TE-associated factors such as GATA3 and CDX2 participate in bovine lineage specification. In this study, we describe the effects of TE-associated factors on the expression of lineage specification marker genes such as SOX2, OCT4, NANOG, GATA6, and SOX17, by using cytosine base editor system. We successfully knockout GATA3 or CDX2 in bovine embryos with a robust efficiency.
