Characterization of distinct states of human naïve and primed pluriopotency

ABSTRACT: Pluripotency of mammalian stem cells is stabilized at different status depending upon the extracellular stimuli of their environment. Now, there is a consensus that mouse embryonic stem cells (mESCs) and iPSCs (miPSCs) represent undifferentiated status very close to ground-state of mammalian development when cultured in optimal condition. Since they have not been activated to commit into any lineages, they are stated as “naïve-state stem cells”. In contrast, human ESCs (hESCs), hiPSCs, and mEpiSCs are considered to possess partially differentiated characteristics compared with mESCs and miPSCs. Thus, they are stated as “primed-state stem cells”. Investigation of the prerequisites for establishment of the naïve-state is significantly important to fully understand mammalian development and to extrapolate the technologies developed with mouse ES/iPS cells for human. We used expression data to understand the gene expression profile and identified distinct characteristics on pluripotent state.

PRDM14 Ensures a Naïve Pluripotency by a Dual Mechanism Involving Signaling and Epigenetic Pathways in Mouse Embryonic Stem Cells

Project description:Mouse embryonic stem cells (mESCs) fluctuate between a naïve inner cell mass (ICM)-like state and a primed epiblast-like state of pluripotency in serum, but are harnessed exclusively in a distinctive, apparently more naïve state of pluripotency (the ground state) with inhibitors for mitogen-activated protein kinase (MAPK) and glycogen synthase kinase 3 pathways (2i). Understanding the mechanism ensuring a naïve state of pluripotency would be critical in realizing a full potential of ESCs. We show here that PRDM14, a PR domain-containing transcriptional regulator, ensures a naïve pluripotency by a dual mechanism: Antagonizing fibroblast growth factor receptor (FGFR) signaling that is activated paradoxically by the core transcriptional circuitry for pluripotency and directs a primed state and repressing de novo DNA methyltransferases that create a primed epiblast-like epigenome. PRDM14 exerts these functions by recruiting polycomb repressive complex 2 (PRC2) specifically to key targets and repressing their expression. Mouse Embryonic Stem Cells (mESCs) or mESC-like cells with different Prdm14 genotypes {Prdm14(+/+), Prdm14(-/-), and Prdm14(-/-) rescued with Avitag-EGFP-Prdm14 transgene [Prdm14(-/-)+AGP14]} are cultured on MEF in different medium [2i, Serum(day 2), Serum+MEK inhibitor (PD0325901) (day 2), Serum without LIF (day2)].

Primed to naïve-like conversion of the common marmoset embryonic stem cells

Project description:Mammalian pluripotent stem cells are thought to exist in two states: naïve and primed states. Generally, unlike those in rodents, pluripotent stem cells in primates including humans are regarded as being in the primed pluripotent state. Recently, several groups reported the existence of naïve pluripotent stem cells in humans. In this study, we report the conversion of primed state embryonic stem cells from common marmoset, a New World monkey, to the naïve state by using transgenes. The cells showed typical naïve state features including dome-like colony morphology, growth factor requirement, gene expression profile, X chromosome activation state, and energy metabolic status. Moreover, interspecies chimeric embryo formation ability with mouse embryos was increased in the naïve state. This technique can be applied in basic medical research using non-human primates such as preclinical use of naïve pluripotent stem cells and generating genetically modified primates.

‘Naïve’ ESRRB+ iPSCs with the capacity for rapid neural differentiation

Project description:Several groups have reported the existence of a form of pluripotency that resembles that of mouse embryonic stem cells (mESCs), i.e., a naïve state, in human pluripotent stem cells; however, the characteristics vary between reports. The nuclear receptor ESRRB is expressed in mESCs and plays a significant role in their self-renewal, but its expression has not been observed in most naïve-like human induced pluripotent stem cells (hiPSCs). In this study, we modified several methods for converting hiPSCs into a naïve state through the transgenic expression of several reprogramming factors. The resulting cells express the components of the core transcriptional network of mESCs, including ESRRB, at high levels, which suggests the existence of naïve-state hiPSCs that are similar to mESCs. We also demonstrate that these cells differentiate more readily into neural cells than do conventional hiPSCs. These features may be beneficial for their use in disease modeling and regenerative medicine.

Tbx3 controls Dppa3 levels to regulate exit from pluripotency towards mesodermal lineage

Project description:Tbx3, a member of the T-box family, plays important roles in development, stem cells, nuclear reprogramming and cancer. Loss of Tbx3 induces differentiation in mouse embryonic stem cells (mESCs). However, we show that mESCs exist in an alternate stable pluripotent state in the absence of Tbx3. In-depth transcriptome analysis of this mESC state reveals Dppa3 as a direct downstream target of Tbx3. Also Tbx3 facilitates the cell fate transition from pluripotent cells to mesoderm progenitors by directly repressing Wnt pathway members required for differentiation. Wnt signaling regulates differentiation of mESCs into mesoderm progenitors and helps maintain a naïve pluripotent state. We show that Tbx3, a downstream target of Wnt signaling, fine-tunes these divergent roles of Wnt signaling in mESCs. In conclusion, we identify a signaling-TF axis that controls the exit of mESCs from a self-renewing pluripotent state towards mesoderm differentiation. ChIPSeq and RNASeq (population and single cell) was performed on the indicated cell lines. Replicates are indicated as needed. The mm9 genome assembly was used. For single cell mRNA-Seq preparation, SSEA1+DAPI- mESCs were sorted and collected.

Novel culture conditions facilitating the induction of naïve pluripotency in human embryonic stem cells

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.

Generation of Naïve Induced Pluripotent Stem Cells from Rhesus Monkey Fibroblasts

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.

Cell signaling coordinates global Polycomb Repressive Complex 2 recruitment and developmental gene expression in murine embryonic stem cells (ChIP-Seq)

Project description:In this study, we provide evidence to show that the expression of PRC2-recruting factor Jarid2 is largely reduced in both naïve mESC and Erk1/Erk2 double knockout (Erk1/2-dKO) mESCs, which can be rescued by reactivation of FGF/MARK signaling in naïve mESCs or ectopic Erk1 expression in Erk1/2-dKO mESCs, suggesting the FGF/ERK signaling positively regulates the Jarid2 expression in mESCs. Consistent with the Jarid2 function in the PRC2 recruitment, the global Ezh2 occupancy and histone H3K27me3 are largely reduced at CpG islands (CGIs) and bivalent promoters in both naïve mESCs and Erk1/Erk2-dKO mESCs, which can be fully restored by ectopic expression of Jarid2 expression, suggesting the reduced Jarid2-mediated PRC2 recruitment is a main molecular mechanism leading to the global reduction of PRC2 occupancy at CpG islands and bivalent promoters in naïve mESCs. At the transcriptional level, although both PRC2 occupancy and histone H3K27me3 modification are reduced at bivalent promoters, there exist two groups of genes with distinct expression status. the FGF/ERK signaling target genes are silenced while the Wnt signaling target genes are largely de-repressed, which is caused by the chemical activation of Wnt/beta-catenin signaling in naïve mESCs. Further ChIP-seq analyses demonstrate an increased occupancy of β-catenin at its activated gene promoters in naïve mESCs. These results suggest the transcriptional activation of bivalent genes in naïve mESCs is predominantly determined by the presence of transcriptional factors but not the status of PRC2 occupancy at gene promoters.
