Single-cell 3D genome structure reveals distinct human pluripotent states (ATAC-Seq)

ABSTRACT: Pluripotent states of embryonic stem cells (ESCs) with distinct transcription profile affect their differentiation capacity and therapeutic potential. By single cell analysis of high-resolution three-dimensional (3D) genome structure, we show that remodeling genome structure is highly associated with pluripotent states of human ESCs (hESCs). Naive pluripotent state is featured with specialized 3D genome structures and clear chromatin compartmentation distinct from primed state. Naive pluripotent state may be achieved by remodeled active euchromatin compartment and less chromatin interaction in the nuclear center. This unique genome organization is linked to elevated chromatin accessibility on enhancers and thus high expression levels of naive pluripotent genes localized in this region. On the contrary, primed state exhibits intermingled genome organization. Moreover, active euchromatin and primed pluripotent genes are distributed in the nuclear periphery and yet repressive heterochromatin densely concentrated in the nuclear center, reducing chromatin accessibility and transcription of naive genes. Thus, inversion or relocation of heterochromatin to euchromatin compartmentation is related to regulating chromatin accessibility and thus define pluripotent states and cell identity.

In vitro capture and characterization of embryonic rosette-stage pluripotency between naive and primed states

Project description:Upon implantation, the naive pluripotent epiblast of the mouse blastocyst generates a rosette, undergoes lumenogenesis and forms the primed pluripotent egg cylinder, able to generate the embryonic tissues. How pluripotency progression and morphogenesis are linked, and whether intermediate pluripotent states exist remain controversial. We identify here a rosette pluripotent state, defined by co-expression of naive factors with transcription factor OTX2. Downregulation of blastocyst WNT signals drives transition into rosette pluripotency by inducing OTX2. The rosette then activates MEK signals that induce lumenogenesis and drive progression to primed pluripotency. Consequently, combined WNT and MEK inhibition supports rosette-like stem cells (RSCs), a self-renewing naive-primed intermediate. RSCs erase constitutive heterochromatin marks and display a primed chromatin landscape, with bivalently marked primed pluripotency genes. Nonetheless, WNT induces reversion to naive pluripotency. The rosette is therefore a reversible pluripotent intermediate where control over both pluripotency progression and morphogenesis pivots from WNT to MEK signals.

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.

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

Project description: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.

In vitro capture and characterization of embryonic rosette-stage pluripotency between naive and primed states (II, single-cell RNA-Seq data)

Project description:Naive pluripotent cells in the implanting mouse blastocyst generate a rosette structure before undergoing lumenogenesis to form the egg cylinder. Simultaneously, they acquire primed pluripotency, the ability to differentiate into the primary germ layers. The existence of discrete intermediate pluripotent states during this transition has not been demonstrated. We identify here a distinct rosette pluripotent state, defined by co-expression of naive factors with transcription factor OTX2. Downregulation of WNT signals in the blastocyst drives transition into rosette pluripotency by inducing OTX2. The rosette then activates MEK signals that induce lumenogenesis and drive progression to primed pluripotency. Consequently, combined WNT and MEK inhibition supports rosette-like stem cells (RSCs), a self-renewing naive-primed intermediate. RSCs gain a unique epigenome that includes erasure of constitutive heterochromatin and bivalent marking of primed pluripotency genes. Notwithstanding this primed chromatin landscape, WNT induces reversion to naive pluripotency. The rosette is therefore a reversible pluripotent intermediate where control over pluripotency progression and morphogenesis pivots from WNT to MEK signals.

TRIM28-Regulated Transposon Repression Is Required for Human Germline Competency and Not Primed or Naive Human Pluripotency

Project description:Transition from primed to naive pluripotency is associated with dynamic changes in transposable element (TE) expression and demethylation of imprinting control regions (ICRs). In mouse, ICR methylation and TE expression are each regulated by TRIM28; however, the role of TRIM28 in humans is less clear. Here, we show that a null mutation in TRIM28 causes significant alterations in TE expression in both the naive and primed states of human pluripotency, and phenotypically this has limited effects on self-renewal, instead causing a loss of germline competency. Furthermore, we discovered that TRIM28 regulates paternal ICR methylation and chromatin accessibility in the primed state, with no effects on maternal ICRs. Taken together, our study shows that abnormal TE expression is tolerated by self-renewing human pluripotent cells, whereas germline competency is not.

Widespread reorganisation of pluripotent factor binding and gene regulatory interactions between human pluripotent states

Project description:The transition from naive to primed pluripotency is accompanied by an extensive reorganisation of transcriptional and epigenetic programmes. However, the role of transcriptional enhancers and three-dimensional chromatin organisation in coordinating these developmental programmes remains incompletely understood. Here, we generated a high-resolution atlas of gene regulatory interactions, chromatin profiles and transcription factor occupancy in naive and primed human pluripotent stem cells, and developed a network-graph approach to examine the atlas at multiple spatial scales. We uncovered highly connected promoter hubs that changed substantially in interaction frequency and in transcriptional co-regulation between pluripotent states. Small hubs frequently merged to form larger networks in primed cells, often linked by newly-formed Polycomb-associated interactions. We identified widespread state-specific differences in enhancer activity and interactivity that corresponded with an extensive reconfiguration of OCT4, SOX2 and NANOG binding and target gene expression. These findings provide new, multilayered insights into the chromatin-based gene regulatory control of human pluripotent states.
