Project description:Conventional embryonic stem cells (ESCs) or induced pluripotent stem cells (iPSCs) derived from primates resemble mouse epiblast stem cells, raising an intriguing question regarding whether the naïve pluripotent state resembling mouse embryonic stem cells (mESCs) exists in primates and how to capture it in vitro. Here we identified several specific signaling modulators that are sufficient to generate rhesus monkey fibroblast-derived iPSCs with the features of naïve pluripotency in terms of growth properties, gene expression profiles, self-renewal signaling, X-reactivation and the potential to generate cross-species chimeric embryos. Interestingly, together with recent reports of naïve human pluripotent stem cells, our findings suggest several conserved signaling pathways shared with rodents and specific to primates, providing significant insights for acquiring naïve pluripotency from other mammal species. In addition, the derivation of rhesus monkey naïve iPSCs also provides a valuable cell source for use in preclinical research and disease modeling. mRNA expression analysis of 4 rhesus monkey naive iPSC lines and 2 primed iPSC lines were examed.

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.

Project description:It is now well recognized that human embryonic stem cells (hESCs)1 closely resemble mouse epiblast stem cells (mEpiSCs)2-5 exhibiting primed pluripotency unlike mouse ESCs (mESCs) which acquire a naïve pluripotent state4-8. Efforts have been made to trigger naïve pluripotency in hESCs9-11 for subsequent unbiased lineage-specific differentiation, a common conundrum faced by primed pluripotent hESCs due to heterogeneity in gene expression existing within and between hESC lines12. We report here a novel culture medium facilitating rapid induction of naïve pluripotency in established hESCs. Our medium also allows derivation of naïve mESCs from blastocyst stage which has not been shown earlier. The established naïve hESCs could survive long-term single cell passaging, maintain a normal karyotype, exhibit upregulation of naïve pluripotency genes and were dependent on signaling pathways similar to naïve mESCs. Also, they undergo global DNA demethylation, cluster together with previously described naïve hESCs13 and show a distinctive long non-coding RNA profile. Collectively, we demonstrate an alternate route to capture naïve pluripotency in hESCs which is fast, reproducible, can be employed to derive naïve mESCs and can induce efficient differentiation. Three primed and matching naive human embryonic stem cell lines were profiled in duplo.

Project description:The epiblast (EPI) is the origin of all somatic and germ cells in mammals, and of the spectrum of pluripotent stem cells (PSCs) in vitro. To explore the ontogeny of human/primate pluripotency, we performed comprehensive single-cell RNA sequencing for pre- and post-implantation EPI development in cynomolgus monkeys. Here we show that after specification in the blastocysts [embryonic day (E)7], cyEPI undergoes major transcriptome changes upon implantation. Thereafter, cyEPI, while generating gastrulating cells (~E13), maintains its transcriptome relatively stably over a week, retaining a unique set of pluripotency genes while acquiring properties for âneuron differentiation.â h/cyPSCs show the highest similarity to post-implantation late cyEPI (~E17), which, despite co-existing with gastrulating cells, bears characteristics of pre-gastrulating mouse EPI (E5.5) and epiblast-like cells (EpiLCs) in vitro. These findings not only reveal divergence/coherence of EPI development, but also identify a developmental coordinate of the spectrum of pluripotency among key species, providing a basis for better regulation of human pluripotency in vitro. Single cell transcriptome analysis of cynomolgus monkey embryo E6-17 and mouse embryo E4.5 - E6.5 as well as of cynomogus monkey embryonic stem cells (ESCs) and mouse ESC, epiblast like cells (EpiLCs), using SC3-seq technology.

Abstract:
BACKGROUND: The transcription factor OCT4 is highly expressed in pluripotent embryonic stem cells which are derived from the inner cell mass of mammalian blastocysts. Pluripotency and self renewal are controlled by a transcription regulatory network governed by the transcription factors OCT4, SOX2 and NANOG. Recent studies on reprogramming somatic cells to induced pluripotent stem cells highlight OCT4 as a key regulator of pluripotency.
RESULTS: We have carried out an integrated analysis of high-throughput data (ChIP-on-chip and RNAi experiments along with promoter sequence analysis of putative target genes) and identified a core OCT4 regulatory network in human embryonic stem cells consisting of 33 target genes. Enrichment analysis with these target genes revealed that this integrative analysis increases the functional information content by factors of 1.3 - 4.7 compared to the individual studies. In order to identify potential regulatory co-factors of OCT4, we performed a de novo motif analysis. In addition to known validated OCT4 motifs we obtained binding sites similar to motifs recognized by further regulators of pluripotency and development; e.g. the heterodimer of the transcription factors C-MYC and MAX, a prerequisite for C-MYC transcriptional activity that leads to cell growth and proliferation.
CONCLUSION: Our analysis shows how heterogeneous functional information can be integrated in order to reconstruct gene regulatory networks. As a test case we identified a core OCT4-regulated network that is important for the analysis of stem cell characteristics and cellular differentiation. Functional information is largely enriched using different experimental results. The de novo motif discovery identified well-known regulators closely connected to the OCT4 network as well as potential new regulators of pluripotency and differentiation. These results provide the basis for further targeted functional studies.
