Zfp281 Coordinates Opposite Functions of Tet1 and Tet2 for Alternative Pluripotent States [ChIP-Seq]

ABSTRACT: Pluripotent cell identity comprises a spectrum of cell states including naive and primed states, which are typified by mouse embryonic stem cells (ESCs) and epiblast-derived stem cells (EpiSCs), respectively. Here we define a pluripotent cell fate (PCF) gene signature based on RNA-seq analysis associated with naive and primed pluripotency acquisition, and identify Zfp281 as a key transcriptional regulator for primed pluripotency and also as a barrier to achieve the naive pluripotency of both mouse and human ESCs. RNA sequencing analysis was performed in WT and Zfp281 null mouse embryonic stem cells under different pluripotent culture conditions. RNA-seq Experiments were carry out in two biological replciates. Genome binding/occupancy profiling of Zfp281 was performed in mouse embryonic stem cells by ChIP sequencing.

Pluripotency is increasingly recognized as a spectrum of cell states defined by their growth conditions. Although naive and primed pluripotency states have been characterized molecularly, our understanding of events regulating state acquisition is wanting. Here, we performed comparative RNA sequencing of mouse embryonic stem cells (ESCs) and defined a pluripotent cell fate (PCF) gene signature associated with acquisition of naive and primed pluripotency. We identify Zfp281 as a key transcription ...[more]

A mass spectrometry survey of chromatin-associated proteins in pluripotency and early lineage commitment

Project description:Pluripotent Embryonic Stem Cells (ESCs) can be captured in vitro in different states, ranging from unrestricted ‘naïve’ to more developmentally constrained ‘primed’ pluripotency. Complexes involved in epigenetic regulation and key transcription factors have been shown to be involved in specifying these distinct states. In this study, we use proteomic profiling of the chromatin landscape in naive pluripotent ESCs, Epistem cells (EpiSCs) and early differentiated ESCs to survey the chromatin in naïve and primed pluripotency and during differentiation. We provide a comprehensive overview of epigenetic complexes situated on the chromatin and identify proteins associated with the maintenance and loss of pluripotency. The findings presented here indicate major compositional alterations of epigenetic complexes starting from ESC priming onwards. Our results contribute to the understanding of ESC differentiation and provide a framework for future studies of lineage commitment of ESCs.

Systematic Identification of Defined Conditions for Induction and Maintenance of Naive Human Pluripotency [ChIP-Seq]

Project description:Embryonic stem cells (ESCs) of mice and humans have distinct molecular and biological characteristics, raising the question whether an earlier ‘naive’ state of pluripotency may exist in humans. Here we took a systematic approach to identify small molecules that support autonomous self-renewal of naive human ESCs based on maintenance of endogenous OCT4 distal enhancer activity, a molecular signature of ground state pluripotency. Iterative chemical screening identified a combination of five kinase inhibitors that induces and maintains OCT4 distal enhancer activity when applied directly to conventional human ESCs. These inhibitors generate a homogeneous population of human pluripotent stem cells in which transcription factors associated with the ground state of pluripotency are highly upregulated. Comparison with previously reported naive human ESCs indicates that our kinase inhibitor cocktail captures a novel pluripotent state in humans that closely resembles mouse ESCs. ChIP-seq data from human embryonic stem cells in naive and primed conditions were generated by deep sequencing using Illumina Hi-Seq 2000.

3D regulatory landscape of human naive pluripotency [RNA-Seq]

Project description:The control of cell identity is orchestrated by transcriptional and chromatin regulators in the context of specific chromosome structures. With the recent isolation of human naive embryonic stem cells (ESCs) representative of the ground state of pluripotency, it is possible to deduce this regulatory landscape in one of the earliest stages of human development. Here we generate cohesin ChIA-PET chromatin interaction data in naive and primed human ESCs and use it to reconstruct and compare the 3D regulatory landscapes of these two stages of early human development. The results reveal shared and stage-specific regulatory landscapes of topological domains and their subdomains, which consist of CTCF-CTCF/cohesin loops and enhancer-promoter/cohesin loops. The enhancer-promoter loop data reveal that genes with key roles in pluripotency are nearly always regulated by one or more super-enhancers, and show that these genes tend to occur in insulated neighborhoods. Our results reveal the key features of the 3D regulatory landscape of early human cells that form the foundation for embryonic development.

Comparison with previously reported naive human ESCs indicates that our kinase inhibitor cocktail captures a novel pluripotent state in humans that closely resembles mouse ESCs. Expression analysis was performed on two groups of human ESC samples: WIBR2 (P12 and P14), WIBR3 (P9) and WIN1 (P10) human ESCs derived in our optimized naive medium (5i/L/A or 6i/L/A, as indicated), and parental WIBR2 and WIBR3 human ESCs in primed human ESC medium.

A Molecular Roadmap of the Phased Progression of Pluripotency

Project description:Pluripotency is highly dynamic and progresses through a continuum of pluripotent stem cell states. The two states that bookend the pluripotency continuum, naïve and primed, are well characterized, but our understanding of the intermediate states and the transitions between them remain incomplete. To address this gap in knowledge, using a previously validated system to induce naive mouse embryonic stem cells (ESCs) to post-implantation pre-grastrulating epiblast-like cells (EpiLCs), we generated comprehensive high-temporal-resolution maps of the proteome, phosphoproteome, transcriptome, and epigenome of ESCs transitioning from naïve to primed pluripotency. Our data provide a comprehensive molecular description of the phased progression of pluripotency and a foundation for investigating mechanisms that regulate pluripotent state transitions.
