Eomes related gene regulation in Definitive Endoderm (NG Capture-C)

ABSTRACT: Precisely co-ordinated activation of lineage specific transcription factors direct cell fate decisions during mouse early development. The T-box transcription factor Eomes is dynamically expressed during mouse gastrulation and is a key regulator of the anterior visceral endoderm (AVE), cardiac mesoderm and definitive endoderm (DE) lineages. The cis-acting regulatory elements that direct spatiotemporally restricted Eomes expression domains have yet to be elucidated. To understand transcriptional regulation of Eomes in Definitive Endoderm open chromatin data was generated by ATAC-seq and histone modifications identified by ChIP-seq. Interactions at the Eomes locus and the loci of two related transcription factors Foxa2 and Lhx1, was also determined by NG Capture-C.

Eomes and Brachyury control pluripotency exit and germ-layer segregation by changing the chromatin state

Project description:We aimed to elucidate molecular mechanisms of first lineage decision in the mouse pluripotent epiblast that segregates mesoderm and endoderm (ME) from neuroectoderm (NE). By analyzing mouse embryonic stem cells (ESCs) and embryos deficient for two T-box (Tbx) transcription factors Eomes and Brachyury we demonstrate that this process is controlled by the changes in the chromatin accessibility of ME gene enhancers and activation of the target genes, but also direct repression the opposing pluripotency and NE gene programs.

Gene expression of sorted Eomes+ and Eomes‒ γδ T cells from spleen of Eomes-IRES-GFP mice.

Project description:Eomesodermin (Eomes) is a transcription factor with a crucial role regulating cytotoxic function, development and survival of immune cells. Although it is known that γδ T cells can express Eomes, its function on those cells is still largely unknown. Using Eomes-IRES-GFP mice we were able to sort for Eomes+ and Eomes‒ γδ T cells populations and get their gene expression profiles, bringing light to the role of Eomes on γδ T cells.

Pluripotency Factors Regulate Definitive Endoderm Specification through Eomesodermin

Project description:Understanding the molecular mechanisms controlling early cell fate decisions in mammals is a major objective towards the development of robust methods for the differentiation of human pluripotent stem cells into clinically relevant cell types. Here, we used human embryonic stem cells (hESCs) to study specification of definitive endoderm in vitro. Using a combination of whole genome expression and ChIP-seq analyses, we established a hierarchy of transcription factors regulating endoderm specification. Importantly, pluripotency factors, namely NANOG, OCT4 and SOX2 have an essential function in this network by actively directing differentiation. Indeed, these transcription factors control the expression of EOMES, which marks the onset of endoderm specification. In turn, EOMES interacts with SMAD2/3 to initiate the transcriptional network governing endoderm formation. Together, these results provide for the first time a comprehensive molecular model connecting the transition from pluripotency to endoderm specification during mammalian development. ChIP-Seq of Eomesodermin binding in human embyonic stem cells, differentiated towards an endodermal fate for 48h in chemically-defined culture media. Includes an input DNA control. Supplementary file GSE26097_README.txt contains descriptions of the raw data files and processed data files.

Tissue-intrinsic beta-catenin signals antagonize Nodal-driven anterior visceral endoderm differentiation

Project description:The anterior-posterior axis of the mammalian embryo is laid down by the anterior visceral endoderm (AVE), an extraembryonic signaling center that is specified within the visceral endoderm. Current models posit that AVE differentiation is promoted globally by epiblast-derived Nodal signals, and spatially restricted by a BMP gradient established by the extraembryonic ectoderm. Here, we report spatially restricted AVE differentiation in bilayered embryo-like aggregates made from mouse embryonic stem cells that lack an extraembryonic ectoderm. Notably, clusters of AVE cells also form in pure visceral endoderm cultures upon activation of Nodal signaling, indicating that tissue-intrinsic factors can restrict AVE differentiation. We identify β-catenin activity as a tissue-intrinsic factor that antagonizes AVE-inducing Nodal signals. Together, our results show how an AVE-like population can arise through interactions between epiblast and visceral endoderm alone. This mechanism may be a flexible solution for axis patterning in a wide range of embryo geometries, and provide robustness to axis patterning when coupled with signal gradients.
