(Submitter supplied) Understanding the molecular underpinnings of pluripotency is a prerequisite for optimal maintenance and application of embryonic stem cells (ESCs). While the protein-protein interactions of core pluripotency factors have been identified in mouse ESCs, their physical interactome in human ESCs (hESCs) has not been explored thus far. Here we mapped the protein-protein interactions of OCT4 in naive and primed hESCs, revealing extensive connections to ATP-dependent nucleosome remodeling complexes. more...

(Submitter supplied) Pioneer transcription factors are able to recognise and bind their motif sequences in inaccessible or closed chromatin, and their ability to achieve this is required to establish new regulatory elements and transcriptional networks during development and cellular reprogramming. An essential feature of this pioneering activity is the transition from inaccessible chromatin to a nucleosome-depleted and accessible chromatin state typical of normal regulatory elements, and this is believed to facilitate further transcription factor binding events. more...

(Submitter supplied) Human and mouse somatic cells can be reprogrammed by the combination of Oct4, Sox2, Klf4, and c-Myc, but the efficiency of reprogramming is low. To better understand the process of reprogramming we sought to identify factors that mediate reprogramming at higher efficiency. For this we established an assay to screen nuclear fractions from the extracts of pluripotent cells based on Oct4 reactivation. We identified components of the ATP-dependent SWI/SNF chromatin-remodeling complex, which when used along with the above four factors increase reprogramming efficiency by five-fold and improve the quality of the reprogrammed cells. These cells were found to be capable of germline transmission and exhibited pluripotency according to gene expression and in vivo and in vitro assays. SWI/SNF was found to replace c-Myc and mediate its effects by facilitating recruitment of Oct4 on target promoters during reprogramming. Thus, somatic cell reprogramming using chromatin-remodeling molecules represents an efficient method of generating reprogrammed cells. DNA-free RNA samples to be hybridized on Illumina expression BeadChips were processed using a linear amplification kit (Ambion) (generating IVT duration: 12h). cRNA samples were quality-checked on a 2100 Bioanalyzer (Agilent) and hybridized as biological triplicates onto MouseWG-6 V2 chips as recommended and using materials / reagents provided by the manufacturer (hybridization time: 18h). The Myc probe on the V2 arrays was found to be defective. The bead intensities were mapped to gene information using BeadStudio 3.2 (Illumina), background correction was performed using the Affymetrix Robust Multi-array Analysis (RMA) background correction model, variance stabilization was performed using log2 scaling, and gene expression normalization was calculated with the quantile method implemented in the lumi package of R-Bioconductor. Data post-processing and graphics were performed with in-house developed functions in Matlab. Hierarchical clusters of genes and samples were performed with a one minus correlation metric and the average (unweighted pair group) linkage method.

(Submitter supplied) In our study, PRDM14 and NFRkB were found to enhance the reprogramming of human fibroblasts to hiPSCs in the presence of OCT4, SOX2, KLF4, with/without c-MYC (OSK/OSKC). To examnie if the obtained hiPSC share similar expression signature with hESC, we conducted the microarray analysis on the hiPSCs, hESCs and fibroblasts. The result showed that all of the examined hiPSCs resembled hESCs, but differed from fibroblasts MRC5.

(Submitter supplied) PRDM14 belongs to the PR (PRDI-BF1 and RIZ) domain proteins (PRDM) family which is a subclass of the SET domain proteins, a common domain found in histone modifying enzymes. PRDM14 has been previously implicated to regulate self-renewal of hESCs as knock-down of PRDM14 induced expression of differentiation marker genes and altered the cellular morphology. We showed that PRDM14 directly regulates the expression of key pluripotency gene POU5F1. more...

(Submitter supplied) We utilized FAIRE-seq to identify accesible chromatin in mouse embryonic-, epiblast-, and neural- stem cells in addition to mouse embryonic fibroblasts. Analysis of these data sets reveal cell type specific chromatin signatures that differentiate naïve and primed pluripotency. Functional analysis of type-specific peaks revealed cell-type specific enhancers.

By single cell analysis of high-resolution three-dimensional (3D) genome structure, we show that remodeling genome structure is highly associated with pluripotent states of human ESCs (hESCs). Naive pluripotent state is featured with specialized 3D genome structures and clear chromatin compartmentation distinct from primed state. more...
