Project description:Elf5 is a transcription factor with pivotal roles in the trophoblast compartment where it reinforces a trophoblast stem cell (TSC)-specific transcriptional circuit. However, Elf5 is also present in differentiating trophoblast cells that have ceased to express other TSC genes such as Cdx2 and Eomes. In the current study we aimed to elucidate the context-dependent role of Elf5 at the interface between TSC self-renewal and onset of differentiation. We demonstrate that precise levels of Elf5 are critical for normal expansion of the TSC compartment and embryonic survival, as Elf5 overexpression triggers precocious trophoblast differentiation. Through integration of protein interactome, transcriptome and genome-wide chromatin immunoprecipitation data we reveal that this abundance-dependent function is mediated through a shift in preferred Elf5 binding partners; in TSCs, Elf5 interaction with Eomes recruits Tfap2c to triply occupied sites at TSC-specific genes driving their expression. By contrast, the Elf5 and Tfap2c interaction becomes predominant as their protein levels increase. This triggers binding to double and single occupancy sites that harbour the cognate Tfap2c motif, causing activation of the associated differentiation-promoting genes. These data place Elf5 at the centre of a stoichiometry-sensitive transcriptional network where it acts as molecular switch governing the balance between TSC proliferation and differentiation.

Project description:This study aims to compare in vivo human trophoblast differentiation into EVTs to different in vitro trophoblast organoids using single-cell and single-nuclei RNA sequencing. The study includes two type of systems: human primary trophoblast organoids (PTO) and trophoblast stem cells (TSCs). Trophoblast stem cell (TSC) lines BTS5 and BTS11 derived by Okae and colleagues were grown as described previously (Okae et al. 2018) and together with EVT media. Primary trophoblast organoids (PTO) were grown and differentiated into EVT as previously described by Turco & Sheridan (Turco et al 2018; Sheridan et al 2020). This study shows that the main regulatory programs mediating EVT invasion in vivo are preserved in in vitro models of EVT differentiation from primary trophoblast organoids and trophoblast stem cells.

Project description:The role of microRNAs (miRNA) in first cell fate choice of the preimplantation mouse embryo remains unresolved, as gene expression and knockout data are conflicting. This cell fate choice generates the extraembryonic lineage of the trophoblast and the embryonic lineage of the epiblast (inner cell mass). The trophoblast differentiates into polar and mural cells, where polar cells contribute to placental development and mural cells to the implantation process and Reichert’s membrane. The inner cell mass further differentiates into the epiblast and primitive endoderm. We used stem cell lines that can be derived from the trophoblast and epiblast lineages to address the role of miRNAs in early lineage cell fate specification and determination. Using embryonic stem cells (ESC) and trophoblast stem cells (TSC) as starting and ending states of cell development we identified a network of TSC expressed miRNAs that are enriched in ESC targets mRNA. We used constitutive and inducible expression of TSC enriched miRNAs in ESC and show that they can drive cell morphology and gene expression profiles similar to trophoblast. Additionally we show that this process required HDAC2 inhibition and is miRNA specific, as cardiac specific miR-1 could not induce trophoblast under these conditions. In contrast to embryo derived and Cdx2 induced trophoblast cells, miRNAs promote a mural TE like cell phenotype. Transplantation into preimplantation mouse embryos showed that miRNA-induced trophoblast preferentially contributes to the mural trophoblast in both the blastocyst and the Reichert’s membrane. Our data support a role for miRNAs and HDACs in the specification of the trophoblast and potentially the polar and mural cell types.

Project description:Cells belonging to trophoblast lineage are required for proper implantation and placentation, as well as the vascular, hematopoietic, and immunological properties of the placenta, a crucial organ mediating dynamic interactions between maternal and fetal tissues. Defects in trophoblast lineage development can cause early pregnancy failure or other pregnancy-related disorders. Despite its pivotal roles, the placenta remains as one of the least studied organs. Until now, only a handful of trophoblast-specific transcription factors (TFs) have been characterized, and underlying regulatory mechanisms modulating trophoblast lineage development remain poorly understood. Here we explore trophoblast stem cell (TSC)-specific super-enhancers (SEs) and subsequently identify SE-associated factors enriched with previously known and many unknown TFs modulating trophoblast lineage development. By mapping direct targets of 28 TSC-specific TFs in TSCs, we construct highly intertwined transcriptional regulatory networks where TFs are co-regulated and linked with signaling pathways, and which function as cellular modules dedicated to trophoblast lineage development. Additionally, we reveal that TSC-specific TFs alter their target sites corresponding to the reshaped enhancers during TSC differentiation. These findings advance our understanding on placenta biology.

Project description:Trophoblast stem cells (TSC) have recently been derived from human embryos, and early first trimester placenta; however, aside from ethical challenges, the unknown disease potential of these cells limits their scientific utility. We have previously established a BMP4-based two-step protocol for differentiation of primed human pluripotent stem cells (hPSC) into functional trophoblast; however, those trophoblast could not be maintained in a self-renewing TSC-like state. Here, we use the first step from this protocol, followed by a switch to a newly-developed TSC media, to derive bona-fide TSC. We show that these cells resemble placenta- and naïve hPSC-derived TSC, based on their transcriptome, as well as in vitro and in vivo differentiation potential. We conclude that primed hPSC can be used to generate functional TSC, through a simple protocol which can be applied to a widely-available set of existing hPSC, including induced pluripotent stem cells derived from patients with known birth outcomes.
