Esrrb function in the extraembryonic ectoderm is required for proper primordial germ cell specification [RNA-seq]

ABSTRACT: Estrogen related receptor beta (Esrrb) is an orphan nuclear receptor that is required for self-renewal and pluripotency in mouse embryonic stem (ES) cells. However, in the early post-implantation mouse embryo, Esrrb is specifically expressed in the extraembryonic ectoderm (ExE) and plays a crucial role in trophoblast development. In this study, to better understand the function of Esrrb in trophoblast lineage cells, we performed microarray analysis of Esrrb-null mutant versus wild-type mouse embryos. To further characterize the regulatory targets of Esrrb, we treated trophoblast stem (TS) cells with either Esrrb inhibitor DES or vehicle and compared their global gene expression profile via RNA-seq analysis. In addition, to ask whether these target genes are directly regulated by Esrrb, we performed Chromatin immunoprecipitation-sequencing (ChIP-seq) analysis of TS cells using anti-Esrrb antibody.

Esrrb function in the extraembryonic ectoderm is required for proper primordial germ cell specification [microarray]

Fgf and Esrrb integrate epigenetic and transcriptional networks that regulate self-renewal of Trophoblast Stem Cells

Project description:Esrrb is a transcription factor implicated in embryonic stem (ES) cell self-renewal, yet its knockout causes intrauterine lethality due to defects in trophoblast development. Here we show that in trophoblast stem (TS) cells, Esrrb is a downstream target of fibroblast growth factor (Fgf) signalling and is critical to drive TS cell self-renewal. In contrast to its occupancy of pluripotency-associated loci in ES cells, Esrrb sustains the stemness of TS cells by direct binding and regulation of TS cell-specific transcription factors including Elf5 and Eomes. To elucidate the mechanisms whereby Esrrb controls the expression of its targets, we characterized its TS cell-specific interactome by mass spectrometry. Unlike in ES cells, Esrrb interacts in TS cells with the histone demethylase Lsd1 and with the RNA Polymerase II-associated Integrator complex. Our findings provide new insights into both, the general and context-dependent wiring of transcription factor networks in stem cells by master transcription factors.

Fgf and Esrrb integrate epigenetic and transcriptional networks that regulate self-renewal of Trophoblast Stem Cells

Project description:Derivation and maintenance of TS cells depends on the presence of Fgf signalling. Numerous gene knock-out experiments identified the mitogen activated kinase Mek/Erk branch of the Fgf signalling pathway as predominantly active in both TS cells and extraembryonic ectoderm. Therefore, we tested changes in expression of the key TS cell transcription factors (TFs) upon Mek/Erk inhibition using the Mek inhibitor PD0325901 (“PD03”). To obtain an unbiased genome-wide coverage of the immediate-early response genes of Mek inhibition in TS cells, we performed RNA-seq analysis after 3h and 24h of PD03 treatment. Notably, of the known TS cell TFs, this analysis confirmed Esrrb as the earliest, most rapidly silenced gene upon PD03 treatment. In order to gain first insights into which genes may be primary targets of Esrrb, we treated TS cells with the synthetic nonsteroidal estrogen diethylstilbestrol (DES), an estrogen-related receptor (Err) antagonist and also performed RNA-seq upon short (24h) and prolonged (4d) DES treatment. Finally, to obtain a comprehensive global overview of the binding sites of Esrrb in TS cells, and of its interaction with Lsd1 and Nr0b1 (Dax1), we performed chromatin immunoprecipitation (ChIP)-seq experiments on these factors.

Dynamics of Sox2 and Esrrb occupancy during the differentiation of embryonic stem cells into trophoblast stem cells.

Project description:To understand the mechanism underlying the versatility in transcriptional regulation by Sox2 and Esrrb, we compared genome-wide binding sites of Sox2 and Esrrb in embryonic stem (ES) cells and trophoblast stem (TS) cells by chromatin immunoprecipitation followed by high-throughput sequencing (ChIP-seq).

ESRRB Facilitates the Conversion of Trophoblast-like Stem Cells from Induced Pluripotent Stem cells by Directly Regulating KRT8 and CDX2

Project description:Porcine induced pluripotent stem cells (piPSCs) could serve as a great model system for human stem cell pre-clinical research. However, the pluripotency gene network of piPSCs, especially the function for the core transcription factor ESRRB, was poorly understood. Here, we constructed ESRRB-overexpressing piPSCs (ESRRB-piPSCs). Compared with the control piPSCs (CON-piPSCs), the ESRRB-piPSCs showed flat, monolayered colony morphology. Moreover, the ESRRB-piPSCs showed greater chimeric capacity into trophectoderm than CON-piPSCs. We found that ESRRB could directly regulate the expressions of trophoblast stem cell (TSC)-specific markers, including KRT8, KRT18 and CDX2, through binding to their promoter regions. Mutational analysis proved that the N-terminus zinc finger domain is indispensable for ESRRB to regulate the TSC markers. Furthermore, this regulation needs the participation of OCT4. Accordingly, the cooperation between ESRRB and OCT4 facilitates the conversion from pluripotent state to the trophoblast-like state.

Temporal effects of BMP4 on mouse embryonic and extraembryonic development

Project description:The developing placenta, originated in the mouse through the extra-embryonic ectoderm (ExE), is essential for mammalian embryonic development. Yet, unbiased characterization of ExE differentiation dynamics and interaction with the embryo proper remains incomplete. Here, we develop a temporal single-cell model of mouse gastrulation that maps continuous and parallel differentiation in embryonic and extraembryonic lineages. This is matched with a 3-way perturbation approach to target signaling from the embryo proper, the ExE alone, or both. We show that ExE specification involves early spatial and transcriptional bifurcation of uncommitted ectoplacental cone cells (EPCs) and chorion progenitors. Early BMP4 signaling from chorion progenitors is required for proper differentiation of uncommitted EPCs and later for their specification towards trophoblast giant cells. We also find bi-phasic regulation by BMP4 in the embryo. The early ExE-originating BMP4 signal is necessary for proper endo-mesoderm bifurcation, allantois, and primordial germ cells (PGCs) specification. However, commencing at E7.5, embryonic-derived BMP4 source restricts PGC pool size by favoring differentiation of their extraembryonic mesoderm precursors towards an allantois fate. ExE and embryonic tissues are therefore entangled in time, space, and signaling axes, highlighting the importance of their integrated understanding and modeling in vivo and in vitro.
