(Submitter supplied) The use of pluripotent stem cells in regenerative medicine and disease modeling is complicated by the variation in differentiation properties between lines. In this study, we characterized 13 human embryonic stem cell. (hESC) and 26 human induced pluripotent stem cell (hiPSC) lines to identify markers that predict neural differentiation behavior. At a general level, markers previously known to distinguish mouse ESCs from epiblast stem cells (EpiSCs) correlated with neural differentiation behavior. more...

(Submitter supplied) Human embryonic stem (hES) cells have the capacities to propagate for extended periods and to differentiate into cell types from all three germ layers both in vitro and in vivo. These characteristics of self-renewal and pluripotency enable hES cells having the potential to provide an unlimited supply of different cell types for tissue replacement, drug screening, and functional genomics studies. The hES-T3 cells with normal female karyotype cultured on either mouse embryonic fibroblasts (MEF) in hES medium (containing 4 ng/ml bFGF) (T3MF) or feeder-free Matrigel in MEF-conditioned medium (supplemented with additional 4 ng/ml bFGF) (T3CM) were found to express very similar profiles of mRNAs and microRNAs, indicating that the unlimited self-renewal and pluripotency of hES cells can be maintained by continuing culture on these two conditions. more...

(Submitter supplied) Pluripotent stem cells (PSCs) deficient for microRNAs (miRNAs), such as Dgcr8-/- or Dicer-/- embryonic stem cells (ESCs), contain no mature miRNA and cannot differentiate into somatic cells. How miRNA deficiency causes differentiation defects remains poorly understood. Here, we report that miR-302 is sufficient to enable neural differentiation of differentiation-incompetent Dgcr8-/- ESCs. Our data showed that miR-302 directly suppresses the tumor suppressor p53, which is modestly upregulated in Dgcr8-/- ESCs and serves as a barrier restricting neural differentiation. more...

(Submitter supplied) Epiblast stem cells (EpiSCs) were derived from the epiblast or the ectoderm (epi/ect) of pre-gastrula stage to late-bud stage mouse embryos. To identify if the EpiSCs retain any original stage specific characteristics or which developmental stage of epi/ect they most closely related to, we performed microarray analysis to compare the gene expression profile of multiple EpiSC lines with that of epi/ect of 7 different stages.

(Submitter supplied) Many small molecular compounds reported were involved in improving reprogramming efficiency during inducing pluripotent stem cells (iPSC) or maintain a blastocyst-like state in embryonic stem cells (ESC), including BIO, CHIR99021 (CHIR), and vitamin C et al. However, the knowledge about these small molecules regulating miRNAs in ESC was limited. To understand the role of miRNAs during small molecules induced ESC maintenance and gain an insight how these small molecules regulates miRNAs expression; we performed small RNA sequencing using Illumina HiSeq 2000 under the compounds treatment. more...

(Submitter supplied) MicroRNAs (miRNA) play an essential role in the regulation of gene expression, influence signaling networks responsible for several cellular processes like differentiation of pluripotent stem cells. Despite several studies on the neurogenesis process, no global analysis of microRNA expression during differentiation of induced pluripotent stem cells (iPSC) to neuronal stem cells (NSC) has been done. Therefore we compared the profile of microRNA expression in iPSC lines and in NSC lines derived from them, using microarray-based analysis. Two different protocols for NSC formation were used: direct and two-step via neural rosette formation. We confirmed the new associations of previously described miRNAs in regulation of NSC differentiation from iPSC. We discovered upregulation of miR-10 family, miR-30 family and miR-9 family and downregulation of miR-302 and miR-515 family. Moreover we showed that miR-10 family play a crucial role in the negative regulation of genes expression belonging to signaling pathways involved in neural differentiation: WNT signaling pathway, focal adhesion, signaling pathways regulating pluripotency of stem cells.

(Submitter supplied) Recent advances in the study of human embryonic stem cells (hESCs) and induced-pluripotent stem cells (iPS) highlight their importance as both model systems for basic research and avenues for therapeutic applications. To gain better insight into these cells, a clearer understanding of their molecular properties is crucial. In this study, we analyze changes in the expression profile of microRNAs (miRNAs) and mRNAs in nine different, National Institutes of Health (NIH)-approved hESC lines. more...

Here, human embryonic stem (ES) cell-derived neural progenitor cells, endothelial cells, mesenchymal stem cells, and microglia/macrophage precursors were combined on chemically-defined poly(ethylene glycol) (PEG) hydrogels and cultured in serum-free media to model cellular interactions of the developing brain. more...

(Submitter supplied) 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). more...

(Submitter supplied) We aimed to determine whether overexpression of endoderm-specific miRNA may affect hESC differentiation. To this end, we analyzed the effect of lentiviral-based overexpression of liver-specific miR-122 on hESC differentiation, using genomewide gene microarrays. Stable overexpression of endoderm-specific miR-122 in hESC resulted in increased expression of a few endodermal markers in spontaneously-differentiating hESC, but had no clear effect on directing differentiation towards an endodermal fate; rather, it delayed the general differentiation of hESC. more...

(Submitter supplied) 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. more...

(Submitter supplied) Human embryonic stem cells (hESCs) have the pluripotency to form any cell type in the body, making them attractive cell sources in drug screening, regenerative medicine, disease and developmental processes modeling. However, not all hESC lines have equal potency to generate desired cell types in vitro, significant variation has been observed for the differentiation efficiency of various human ESC lines, and the precise underpinning molecular mechanism are still unclear. more...

(Submitter supplied) Two major goals for regenerative medicine are to reproducibly transform adult somatic cells into a pluripotent state and to control their differentiation into specific cell fates. These goals could be furthered by obtaining a complete picture of the RNA isoforms produced by these cells due to alternative splicing (AS) and alternative promoter selection (APS). To investigate the roles of AS and APS, reciprocal exon-exon junctions were interrogated on a genome-wide scale in differentiating mouse embryonic stem cells (ESCs), mouse myometrium throughout gestation and cardiac remodeling with disease using a prototype Affymetrix microarray. more...

(Submitter supplied) Groucho related gene 5 (GRG5) is a multifunctional protein that has been implicated in late embryonic and postnatal mouse development. Here, we describe a previously unknown role of GRG5 in early developmental stages by analyzing its function in stem cell fate decisions. By both loss and gain of function approaches we demonstrate that ablation of GRG5 deregulates the Embryonic Stem Cell (ESC) pluripotent state whereas its overexpression leads to enhanced self-renewal and acquisition of cancer cell-like properties. more...
