Genome-wide DNA methylation pattern changes in ESC, and EPSC after treated with T09

ABSTRACT: Embryonic stem cells upon extrinsic induction could self-assemble into blastocyst-like structures. However, the intrinsic regulation of such blastoid forming potential remain to be addressed. We discover that the activity of nuclear receptor subfamily 1, group H, member 2 (Nr1h2) in expanded potential stem cell (EPSC) positively correlates with blastoid efficiency and quality. In addition, Nr1h2 agonist, T0901317, improves natural blastocyst development. Surprisingly, Nr1h2-activated ESC (NrESC) is rewired towards a distinct pluripotency state that is capable of self-organizing into blastoids and contribute to embryonic and extraembryonic lineage. We hypothesize that Nr1h2 activation broadly affects the DNA methylation to rewire ESC state. Indeed, from WGBS data, we observe that genome-wide DNA methylation differences in NrESC or EPSC after treated with T09 . In summary, our study demonstrates a novel Nr1h2-centric regulation of expanded pluripotency.

Analysis of Nr1h2 and H3K27ac genomic binding targets in ESC and EPSC under Nr1h2 activation

Project description:ChIP-seq for Nr1h2 in NrESC, ESC. H3K27ac ChIP-seq in NrESC, ESC, EPSC, EPSCT09 Embryonic stem cells upon extrinsic induction could self-assemble into blastocyst-like structures. However, the intrinsic regulation of such blastoid forming potential remain to be addressed. We discover that the activity of nuclear receptor subfamily 1, group H, member 2 (Nr1h2) in expanded potential stem cell (EPSC) positively correlates with blastoid efficiency and quality. In addition, Nr1h2 agonist, T0901317, improves natural blastocyst development. Surprisingly, Nr1h2-activated ESC (NrESC) is rewired towards a distinct pluripotency state that is capable of self-organizing into blastoids and contribute to embryonic and extraembryonic lineage. We hypothesize that Nr1h2 activation broadly affects the transcriptome landscape by regulating chromatin accessibility and epigenome to rewire ESC state. Indeed, from Nr1h2 and H3K27Ac ChIP-seq, we observe that annotated genes with upregulated Nr1h2 binding as well as H3K27Ac marks in NrESC or EPSC treated with T09 are enriched in processes such as lipid metabolism, pluripotency maintenance and trophectoderm maturation, which are known to be essential to blastocyst development. In summary, our study demonstrates a novel Nr1h2-centric regulation of expanded pluripotency.

ATAC-seq in NrESC

Project description:ATAC-seq in NrESC_1, NrESC_16, ESC, EPSC Embryonic stem cells upon extrinsic induction could self-assemble into blastocyst-like structures. However, the intrinsic regulation of such blastoid forming potential remain to be addressed. We discover that the activity of nuclear receptor subfamily 1, group H, member 2 (Nr1h2) in expanded potential stem cell (EPSC) positively correlates with blastoid efficiency and quality. In addition, Nr1h2 agonist, T0901317, improves natural blastocyst development. Surprisingly, Nr1h2-activated ESC (NrESC) is rewired towards a distinct pluripotency state that is capable of self-organizing into blastoids and contribute to embryonic and extraembryonic lineage. We hypothesize that Nr1h2 activation broadly affects the transcriptome landscape by regulating chromatin accessibility and epigenome to rewire ESC state. Indeed, from ATAC-seq analysis, we observe some genomic regions progressively gained accessibility in NrESC over passages, which lead to a unique chromatin accessibility profile in NrESC compared to conventional ESC and EPSC. Binding motifs of Pou5f1, Sox2 and Tead4, which are known master regulator of blastocyst lineage specification, showed gained accessibility in NrESC. In summary, our study demonstrates a novel Nr1h2-centric regulation of expanded pluripotency in terms of chromatin reorganization.

Single-cell RNA-seq for mouse NrESC-blastoids

Project description:Embryonic stem cells upon extrinsic induction could self-assemble into blastocyst-like structures. However, the intrinsic regulation of such blastoid forming potential remain to be addressed. We discover that the activity of nuclear receptor subfamily 1, group H, member 2 (Nr1h2) in expanded potential stem cell (EPSC) positively correlates with blastoid efficiency and quality. In addition, Nr1h2 agonist, T0901317, improves natural blastocyst development. Surprisingly, Nr1h2-activated ESC (NrESC) is rewired towards a distinct pluripotency state that is capable of self-organizing into blastoids and contribute to embryonic and extraembryonic lineage. We aim at characterizing the NrESC-derived blastoids by single-cell RNA-seq and show that blastoid comprise of epiblast-like, trophectoderm-like and primitive endoderm-like populations, which is the same as blastocyst composition and shows respective gene marker expression for each cluster. Thus, NrESC has attained a unique expanded pluripotency state driven by Nr1h2 activation.

Mouse ESC Nr1h2 interactome under T09 treatment

Project description:The intrinsic regulators of stem cell-based embryo models are not well studied. We show that Nr1h2 activation enables conventional ESCs to form blastoids with better implantation and higher blastocyst rates. We identified Nr1h2 transcriptional interactome by CoIP-MS using FLAG antibody to immunoprecipitate Nr1h2-FLAG and its partners in ESC overexpressing Nr1h2-FLAG.

The THO complex regulates pluripotency gene mRNA export to control embryonic stem cell self-renewal and somatic cell reprogramming (RNA-IP)

Project description:Embryonic stem cell (ESC) self-renewal and differentiation is governed by a comprehensive regulatory network. Although the transcriptional regulation has been extensively investigated, post-transcriptional mechanisms controlling the ESC state are poorly understood. Here we describe a critical role of the THO complex in ESC self-renewal and differentiation. We show that THO preferentially interacts with pluripotency gene transcripts through Thoc5, and is required for self-renewal by regulating their export and expression. During differentiation, THO loses its interaction with those transcripts due to reduced Thoc5 expression, which leads to decreased expression of pluripotency proteins and facilitates differentiation. Finally, THO is also important for the establishment of pluripotency, as its depletion inhibits somatic cell reprogramming and blastocyst development. Together, our data indicates that THO regulates pluripotency gene mRNA export to control ESC self-renewal and differentiation, and uncovers a novel mechanism of post-transcriptional regulation in stem cell fate specification. RNA IP was conducted by use of antibody against Thoc2, the precipitated RNA was used to generate library using illumina Kit, and subsequently sequenced by miSeq

The THO complex regulates pluripotency gene mRNA export to control embryonic stem cell self-renewal and somatic cell reprogramming (microarray)

Project description:Embryonic stem cell (ESC) self-renewal and differentiation are governed by a broad-ranging regulatory network. Although the transcriptional regulatory mechanisms involved have been investigated extensively, post-transcriptional regulation is still poorly understood. Here we describe a critical role of the THO complex in ESC self-renewal and differentiation. We show that THO preferentially interacts with pluripotency gene transcripts through Thoc5, and is required for self-renewal at least in part by regulating their export and expression. During differentiation, THO loses its interaction with those transcripts due to reduced Thoc5 expression, leading to decreased expression of pluripotency proteins that facilitates exit from self-renewal. THO is also important for the establishment of pluripotency, as its depletion inhibits somatic cell reprogramming and blastocyst development. Together, our data indicate that THO regulates pluripotency gene mRNA export to control ESC self-renewal and differentiation, and therefore uncover a role for this aspect of post-transcriptional regulation in stem cell fate specification. mouse J1 cells were transfected with non-targeting (NT), Thoc2, and Thoc5 siRNAs. Total RNA was isolated 96 hours after transfection.

Podocalyxin-Like Protein 1 Regulates Pluripotency through the Cholesterol Biosynthesis Pathway

Project description:Deciphering signaling mechanisms critical for the extended pluripotent stem cell (EPSC) state and primed pluripotency is necessary for understanding embryonic development. Here, we identify a membrane protein, Podocalyxin-like protein 1 (PODXL) as being essential for extended and primed pluripotency. Alteration of PODXL expression levels affects self-renewal, protein expression of c-MYC and telomerase, and induced pluripotent stems cell (iPSC) and EPSC colony formation. PODXL is the first membrane protein reported to regulate de novo cholesterol biosynthesis, and human pluripotent stem cells (hPSCs) are more sensitive to cholesterol depletion than fibroblasts. The addition of exogenous cholesterol fully restores PODXL knockdown-mediated loss of pluripotency. PODXL affects lipid raft dynamics via the regulation of cholesterol. PODXL recruits the RAC1/CDC42/actin network to regulate SREBP1 and SREBP2 maturation and lipid raft dynamics. Single-cell RNA sequencing reveals PODXL overexpression enhanced chimerism between human cells in mouse host embryos (hEPSCs 57%). Interestingly, in the human-mouse chimeras, laminin and collagen signaling-related pathways are dominant in PODXL overexpressing cells. We conclude that cholesterol regulation via PODXL signaling is critical for ESC/EPSC.

Establishment of bovine expanded potential stem cells

Project description:Embryonic stem cells (ESCs) and induced pluripotent stem cells have the potential to differentiate to all cell types of an adult individual and are useful for studying development and for translational research. However, extrapolation of mouse and human ESC knowledge to deriving stable ESC lines of domestic ungulates and large livestock species has been challenging. In contrast to ESCs that are usually established from the blastocyst, mouse expanded potential stem cells (EPSCs) are derived from four-cell and eightcell embryos. We have recently used the EPSC approach and established stem cells from porcine and human preimplantation embryos. EPSCs are molecularly similar across species and have broader developmental potential to generate embryonic and extraembryonic cell lineages. We further explore the EPSC technology for mammalian species refractory to the standard ESC approaches and report here the successful establishment of bovine EPSCs (bEPSCs) from preimplantation embryos of both wild-type and somatic cell nuclear transfer. bEPSCs express high levels of pluripotency genes, propagate robustly in feeder-free culture, and are genetically stable in long-term culture. bEPSCs have enriched transcriptomic features of early preimplantation embryos and differentiate in vitro to cells of the three somatic germ layers and, in chimeras, contribute to both the embryonic (fetal) and extraembryonic cell lineages. Importantly, precise gene editing is efficiently achieved in bEPSCs, and genetically modified bEPSCs can be used as donors in somatic cell nuclear transfer. bEPSCs therefore hold the potential to substantially advance biotechnology and agriculture.
