Microarray expression profiling of conventional and reset human pluripotent stem cells

ABSTRACT: Human pluripotent cells were reset to ground state pluripotency by transient overexpression of NANOG and KLF2 and subsequent inhibition of ERK and protein kinase C. Transcriptional profiling of H9 parental and clonal lines, and induced pluripotent stem cells derived from adult fibroblast and adipose cell types was carried out in reset and conventional culture conditions.

Current human pluripotent stem cells lack the transcription factor circuitry that governs the ground state of mouse embryonic stem cells (ESC). Here, we report that short-term expression of two components, NANOG and KLF2, is sufficient to ignite other elements of the network and reset the human pluripotent state. Inhibition of ERK and protein kinase C sustains a transgene-independent rewired state. Reset cells self-renew continuously without ERK signaling, are phenotypically stable, and are kary ...[more]

RNA sequencing of conventional and reset human pluripotent stem cells

Project description:Human pluripotent cells were reset to ground state pluripotency by transient overexpression of NANOG and KLF2 and subsequent inhibition of ERK and protein kinase C. Transcriptional profiling of reset cells and conventional pluripotent stem cell cultures was carried out by RNA-seq, in tandem with mouse embryonic stem cells propagated under similar conditions to assess the combinatorial effects of MEK inhibitor PD0325901, GSK3 inhibitor CHIR99021 and PKC inhibitor Go6983.

Resetting Transcription Factor Control Circuitry Towards Ground State Pluripotency In Human

Project description:Current human pluripotent stem cells lack the transcription factor circuitry that governs the ground state of mouse embryonic stem cells (ESC). Here we report that short-term expression of two components, NANOG and KLF2, is sufficient to ignite other elements of the network and reset the human pluripotent state. Inhibition of ERK and protein kinase C signalling sustains a transgene-independent rewired state. Reset cells self-renew continuously without ERK signalling, are phenotypically stable and karyotypically intact. They differentiate in vitro and form teratomas in vivo. Metabolism is reprogrammed in reset cells with activation of mitochondrial respiration as in ESC. DNA methylation is dramatically reduced and transcriptome state is globally realigned across multiple cell lines. Depletion of ground state transcription factors, TFCP2L1 or KLF4 has marginal impact on conventional human pluripotent stem cells, but collapses the reset state. These findings demonstrate feasibility of installing and propagating functional control circuitry for ground state pluripotency in human cells.

RNA-seq of chemically reset human naive pluripotent stem cells

Project description:A simple method is presented to reset human pluripotent cells to a naive state via transient histone deacetylase inhibition and maintenance in chemically-defined naive stem cell culture media. Cells can be reset without transgenes and expanded continuously either on feeders or alternative substrates in feeder-free conditions. Multiple cell lines of varying origin were reset and characterised in parallel with conventionally cultured counterparts.

Karyotype analysis of human naive embryonic stem cells

Project description:Human pluripotent cell lines were derived from blastocyst-stage embryos and propagated in self-renewal conditions that maintain features of naive pluripotency characteristic of mouse embryonic stem cells. Genomic integrity of the HNES1 cell line was assessed with the Affymetrix CytoScan 750K array.

Tfe3-bound regions in naive pluripotent mouse embryonic stem (ES) cells

Project description:The bHLH transcription factor Tfe3 is a powerful regulator of pluripotency and we report a genome-wide analysis of Tfe3 occupancy in mouse ES cells. Nuclear localization of Tfe3 is inhibited by a protein complex containing the tumor-suppressor Folliculin (Flcn) and we also determine Tfe3 binding sites in ES cells expressing an shRNA targeting Flcn. Specificity is controlled for by using unspecific IgGs and ES cells expressing an shRNA targeting Tfe3. ChIP-Seq profiling of Tfe3 in ES cells

Rapid functional annotation of native enhancers in embryonic stem cells with a Neisseria meningitidis CRISPR-Cas9 system (BeadChip)

Project description:Gene regulatory elements such as enhancers have profound effects on cellular function, health, and disease. Our understanding of mammalian enhancer function is limited by the lack of a technology that would allow for a rapid and thorough test of their cell type-specific function. Here, we describe a novel Cas9-effector system that enables rapid testing and functional annotation of native enhancers in embryonic stem cells. Total RNA obtained from R26 dCas9-effector mESC lines after viral delivery of sgRNAs directed against proximal promoter or enhancer regions

An alternative pluripotent state confers interspecies chimaeric competency [Microarray]

Project description:Here we show that by simple modulation of extrinsic signaling pathways, a new class of pluripotent stem cells, referred to as intrinsic state-epiblast stem cells (IS-EPIs), could be efficiently derived from different stages of the early embryo. IS-EPIs share features of primed pluripotency yet are distinct from EpiSCs in their molecular characteristics and ability to colonize post-implantation embryos. We performed Microarray analysis and compared global gene expression pattern among amplified RNA samples from ESCs, EpiSCS, IS-EPIs as well as in vivo isolated Epiblasts. Examination of global gene expression profiles multiple pluripotent stem cell types

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.
