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

ABSTRACT: 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.

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.

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.

Characterization of distinct states of human naïve and primed pluriopotency

Project description: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.

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.

ESRRB Facilitates the Conversion of Trophoblast-like Stem Cells from Induced Pluripotent Stem cells by Directly Regulating KRT8 and CDX2

Project description:Porcine induced pluripotent stem cells (piPSCs) could serve as a great model system for human stem cell pre-clinical research. However, the pluripotency gene network of piPSCs, especially the function for the core transcription factor ESRRB, was poorly understood. Here, we constructed ESRRB-overexpressing piPSCs (ESRRB-piPSCs). Compared with the control piPSCs (CON-piPSCs), the ESRRB-piPSCs showed flat, monolayered colony morphology. Moreover, the ESRRB-piPSCs showed greater chimeric capacity into trophectoderm than CON-piPSCs. We found that ESRRB could directly regulate the expressions of trophoblast stem cell (TSC)-specific markers, including KRT8, KRT18 and CDX2, through binding to their promoter regions. Mutational analysis proved that the N-terminus zinc finger domain is indispensable for ESRRB to regulate the TSC markers. Furthermore, this regulation needs the participation of OCT4. Accordingly, the cooperation between ESRRB and OCT4 facilitates the conversion from pluripotent state to the trophoblast-like state.

ChIP-seq of Klf2 in mouse embryonic stem cells (Serum/LIF and 2i)

Project description:The self-renewing pluripotent state was first captured in mouse embryonic stem cells (mESCs) over two decades ago. The standard condition requires the presence of serum and LIF, which provide growth promoting signals for cell expansion. However, there are pro-differentiation signals which destabilize the undifferentiated state of mESCs. The dual inhibition (2i) of the pro-differentiation Mek/Erk and Gsk3/Tcf3 pathways in mESCs is sufficient to establish an enhanced pluripotent “ground state” which bears features resembling the pre-implantation mouse epiblast. Gsk3 inhibition alleviates the repression of Esrrb, a transcription factor that can substitute for Nanog function in mESCs. The molecular mechanism that is mediated by Mek inhibition is however not clear. In this study, we investigate the pathway through which Mek inhibition operates to maintain ground state pluripotency. We have found that in mESCs, Kruppel-like factor 2 (Klf2) is a protein target of the Mek/Erk pathway; and that Klf2 protein is phosphorylated by Erk2 and subsequently degraded through the proteosome. It is therefore by Mek-inhibition through PD0325901 or 2i that enables the stabilization and accumulation of Klf2 to sustain ground state pluripotency. Importantly, we found that Klf2-null mESCs, while viable under LIF/Serum conditions, cannot be maintained and eventually gradually die within a few passages. Our result thus demonstrates that Klf2 is an essential factor of ground state pluripotency. Collectively, our study defines the Mek/Klf2 axis that cooperates with the Gsk3/Esrrb pathway in mediating ground state pluripotency.

Genome-wide maps of ESRRB binding in pluripotent (2iL) and differentiated (48h, 96h) mES cells

Project description:We report the application of sequencing technology for profiling of genome-wide ESRRB binding in mouse ES cells. We generated genome-wide chromatin-state maps of mouse embryonic stem cells maintained in pluripotent state (2iL) and differentiated for 48 and 96 hours (48 and 96). We find that the large majority of ESRRB binding occurs in 2iL and at 48 hours and that several formative genes promoters are bound by ESRRB in 2iL and at 48h. Moreover ESRRB peaks on naïve genes (e.g. Tfcp2l1, Nanog) decrease as soon as cells start differentiating while peaks on formative genes are present in 2iL and the signal is maintained (or increased) at 48 hours, further endorsing the concept of Esrrb as a direct activator of the formative gene program during the Reversible phase.
