VGLL1 cooperates with TEAD4 to control human trophectoderm lineage specification.

Project description:In contrast to rodents, the mechanisms underlying human trophectoderm and early placenta specification are understudied due to ethical barriers and the scarcity of embryos. Recent reports have shown that human pluripotent stem cells (PSCs) can differentiate into trophectoderm (TE)-like cells (TELCs) and trophoblast stem cells (TSCs), offering a valuable in vitro model to study early placenta specification. Here, we demonstrate that the VGLL1 (vestigial-like family member 1), which is highly expressed during human and non-human primate TE specification in vivo but is negligibly expressed in mouse, is a critical regulator of cell fate determination and self-renewal in human TELCs and TSCs derived from naïve PSCs. Mechanistically, VGLL1 partners with the transcription factor TEAD4 (TEA domain transcription factor 4) to regulate chromatin accessibility at target gene loci through histone acetylation and acts in cooperation with GATA3 and TFAP2C. Our work is relevant to understand primate early embryogenesis and how it differs from other mammalian species.

Initiation of trophectoderm lineage specification in mouse embryos is independent of Cdx2.

Project description:The separation of the first two lineages - trophectoderm (TE) and inner cell mass (ICM) - is a crucial event in the development of the early embryo. The ICM, which constitutes the pluripotent founder cell population, develops into the embryo proper, whereas the TE, which comprises the surrounding outer layer, supports the development of the ICM before and after implantation. Cdx2, the first transcription factor expressed specifically in the developing TE, is crucial for the differentiation of cells into the TE, as lack of zygotic Cdx2 expression leads to a failure of embryos to hatch and implant into the uterus. However, speculation exists as to whether maternal Cdx2 is required for initiation of TE lineage separation. Here, we show that effective elimination of both maternal and zygotic Cdx2 transcripts by an RNA interference approach resulted in failure of embryo hatching and implantation, but the developing blastocysts exhibited normal gross morphology, indicating that TE differentiation had been initiated. Expression of keratin 8, a marker for differentiated TE, further confirmed the identity of the TE lineage in Cdx2-deficient embryos. However, these embryos exhibited low mitochondrial activity and abnormal ultrastructure, indicating that Cdx2 plays a key role in the regulation of TE function. Furthermore, we found that embryonic compaction does not act as a 'switch' regulator to turn on Cdx2 expression. Our results clearly demonstrate that neither maternal nor zygotic Cdx2 transcripts direct the initiation of ICM/TE lineage separation.
