Genetic Redundancy of GATA Factors in Extraembryonic Trophoblast Lineage Ensures Progression of both Pre and Postimplantation Mammalian Development [RNA-seq]

Project description:GATA transcription factors are implicated in establishing cell fate during mammalian development. In early mammalian embryos, GATA3 is selectively expressed in the extraembryonic trophoblast lineage and regulates gene expression to promote trophoblast fate. However, trophoblast-specific GATA3 function is dispensable for early mammalian development. Here, using dual conditional knockout mice, we show that genetic redundancy of GATA3 with paralog GATA2 in trophoblast progenitors ensures the successful progression of both pre and postimplantation mammalian development. Stage-specific gene deletion in trophoblasts reveals that loss of both GATA genes, but not either one alone, leads to embryonic lethality prior to the onset of their expression within the embryo proper. Using ChIP-seq and RNA-seq analyses, we define the global targets of GATA2/GATA3 and show that they directly regulate a large number of common genes to orchestrate stem vs. differentiated trophoblast fate. Also, in trophoblast progenitors GATA factors directly regulate BMP4, Nodal and Wnt signaling components that promote embryonic-extraembryonic signaling cross-talk, essential for the development of the embryo proper. Our study provides genetic evidence that impairment of trophoblast-specific GATA2/GATA3 function could lead to early pregnancy failure.

Cut and run analysis in human trophoblast stem cells (CT27) upon pulling down with GATA2 and GATA3 antibody

Project description:GATA transcription factors, particularly GATA2 and GATA3 are selectively expressed in the extraembryonic trophoblast lineage and regulates gene expression to promote trophoblast self-renewal during mammalian development. However, we have a poor understanding about the contribution of these GATA factors, in the process of syncytiotrophoblast (SynT) development. Thus, the goal of this study is to define the importance of GATA2 and GATA3 in orchestrating a global gene expression program that poises and commits mammalian trophoblast stem cells to the SynT lineage. Using the cut and run technique for GATA2 and GATA3 antibodies in the human trophoblast stem cells we are aiming to identify the direct targets of the GATA transcription factors that are essential for determining the SynT lineage. Three individual experiments were performed.

Human and marmoset trophoblast stem cells differ in signalling requirements and recapitulate divergent modes of trophoblast invasion

Project description:We derive experimental conditions for the derivation of marmoset trophoblast like cells. Marmoset naïve PSC form extraembryonic mesoderm in human TSC conditions, whilst TGFβ/NODAL, FGF/ERK and WNT signalling control marmoset peri- and postimplantation trophoblast identity.

Zfp281 shapes the transcriptome of trophoblast stem cells and is essential for placental development

Project description:Placental development is a key event in mammalian reproduction and embryogenesis. However, the molecular basis underlying extraembryonic lineage specification and subsequent placental development is not fully understood. Through a genetic screen, we identified Zfp281 as a key factor for extraembryonic development. Disruption of Zfp281 in mice caused severe defects in extraembryonic as well as embryonic tissues. Importantly, Zfp281 was preferentially expressed in the trophoblast stem cell population in an FGF-dependent manner and ensured the expression of genes necessary for placental development. Through the analysis of transcriptome and epigenome, we identified Zfp281 as an important factor to shape the transcriptome of mammalian trophoblast stem cells.

Establishment of mouse primitive endoderm stem cell lines [scRNA-Seq II]

Project description:The mammalian blastocyst consists of three distinct cell types: epiblast, trophoblast (TB), and primitive endoderm (PrE). Although embryonic stem cells (ESCs) and trophoblast stem cells (TSCs) retain the functional properties of Epi and TB, the currently available extraembryonic endoderm cells (XENC) do not fully recapitulate the developmental potential of PrE. Here we report derivation of primitive endoderm stem cells (PrESCs) in mice. PrESCs express both PrE and pluripotency marker genes like founder PrE. These cells are efficiently incorporated into PrE upon blastocyst injection, generate functionally competent PrE-derived tissues, and support fetal development of PrE-depleted blastocysts in chimeras. Establishment of PrESCs therefore represents a significant step-forward in elucidating the mechanisms for PrE specification and subsequent pre- and post-implantation development.

Single cell RNA sequencing analysis using embryonic day 9.5 placenta from control and GATA DKO mice

Project description:The placenta establishes a maternal–fetal exchange interface which ensures transportation of nutrients and gases between the mother and the fetus. A critically conserved step in the establishment of this exchange surface in mammals is the fusion of trophoblast cells into a multinucleated syncytiotrophoblasts (SynT). In mice, SynTs develop via differentiation of the labyrinth trophoblast progenitors (LaTP) of the developing placenta, and in humans, SynTs develop via differentiation of villous cytotrophoblast (CTB) progenitors. Despite being an indispensable step for mammalian development in utero, conserved molecular mechanisms that ensure SynT development are poorly understood. Herein, we show that GATA2 and GATA3 (GATA factors) plays an essential role in labyrinth trophoblast progenitors (LaTPs) thereby committing these cells towards the SynT differentiation program. Mature syncytial layer specific immunostaining with established markers, and ultrastructure analysis of the labyrinth revealed that the loss of GATA factors was impairing the formation of mature SynT cells. We therefore focused our attention on the status of the labyrinth progenitor trophoblast cells in the GATA DKO vs the control placentae. To do that we performed single cell RNA Sequencing (scRNA-Seq) with E9.5 control and Gcm1Cre GATA KO placentae.

Derivation of trophoblast stem cells from naïve human pluripotent stem cells [ATAC-seq]

Project description:Naïve human pluripotent stem cells (hPSCs) provide a unique experimental platform of cell fate decisions during pre-implantation development, but their lineage potential remains incompletely characterized. As naïve hPSCs share transcriptional and epigenomic signatures with trophoblast cells, it has been proposed that the naïve state may have enhanced predisposition for differentiation along this extraembryonic lineage. Here we examined the trophoblast potential of isogenic naïve and primed hPSCs. We found that naïve hPSCs can directly give rise to human trophoblast stem cells (hTSCs) and undergo further differentiation into both extravillous and syncytiotrophoblast. In contrast, primed hPSCs do not support hTSC derivation, but give rise to non-self-renewing cytotrophoblasts in response to BMP4. Global transcriptome and chromatin accessibility analyses indicate that hTSCs derived from naïve hPSCs acquire features of pre-implantation trophectoderm. The derivation of hTSCs from naïve hPSCs will enable elucidation of early mechanisms that govern normal human trophoblast development and associated pathologies.
