Gene expression profile of human embryonic stem cells growth in low concentrations of nitric oxide

ABSTRACT: Identification of genes regulated in human embryonic stem cells by the effect of low concentrations of nitric oxide. The transcriptome of cells treated with NO were compared with that of cells cultured in abscense of LIF, and undifferentiated ES cells cultured in presence of LIF. The H181 hES cell line was used for the experiments. These data complement a previous study realized in mES cells under the same NO conditions . The aim of the work is to know how NO modify transcriptome of ES cells and how participate in the modulation of self renewal and differentiation.

Gene expression profile of human embryonic stem cells growth in low concentrations of nitric oxide

Project description:Identification of genes regulated in human embryonic stem cells by the effect of low concentrations of nitric oxide. The transcriptome of cells treated with NO were compared with that of cells cultured in abscense of LIF, and undifferentiated ES cells cultured in presence of LIF. The H181 hES cell line was used for the experiments. These data complement a previous study realized in mES cells under the same NO conditions . The aim of the work is to know how NO modify transcriptome of ES cells and how participate in the modulation of self renewal and differentiation. Passages between 72 and 74 of the H181 cell line were cultured on Matrigel-coated tissue culture plates in presence of 8ng/ml of bFGF for maintain them undifferentiated (control). For treatments, cells were cultured in the absence of bFGF to induce differentiation and treat cells with 2uM of DETA/NO. Cells were grown for 6 days mantaining the conditions of the treatment each 19 hours. Dietilentriamine-NO (DETA-NO) (Sigma) was used as donor of nitric oxide. Expression data of cells treated with NO in absence of bFGF were compared with cells cultured in absence of this, in order to observe how the treatment affects the transcriptome, and if there is some similarity with undifferentiated condition in presence of bFGF.

Gene expression profile of mouse embryonic stem cells (D3-pOCT-mESC) grown in low concentrations of nitric oxide

Project description:In order to identify the genes regulated in mouse embryonic stem cells (mESC) by the effect of low concentrations of nitric oxide (NO), we analysed the transcriptome of cells treated with NO and compared it to those of cells cultured in the absence of leukemia inhibitory factor (LIF), and in the presence of LIF. We used the cell line D3-pOct4, which carries the enhanced Green Fluorescence Protein gene (eGFP) under the control of the Oct-4 promotor. This line is continuously maintained in the undifferentiated state in the presence of LIF, in comparison with the wild type line .

We used the cell line D3-pOct4, which carries the enhanced Green Fluorescence Protein gene (eGFP) under the control of the Oct-4 promotor. This line is continuously maintained in the undifferentiated state in comparison with the wild type line in the presence of LIF. Experiment Overall Design: D3-pOct4 cells cultured in the presence of 1000 U/ml of LIF, in the absence of LIF, and in the absence of LIF with 2uM of diethylenetriamine nitric oxide adduct (DETA)/NO were grown for 7 days, maintaining the conditions of the treatment everyday. DETA-NO (Sigma) was used as donor of nitric oxide. RNA was extracted and analyzed by Bioanalyzer of Agilent. The cDNA microarray chip used was Mouse Genome 430_2.0 (Affymetrix) and the data were analyzed with GeneChip Operating System v1.4.0.036 using global scaling as the normalization method.

Differential gene expression during embryoid body (EB) formation of mouse embryonic stem cells when Hnrnpll was depleted

Project description:This work indicates Hnrnpll depletion mES cells cannot exit from pluripotency programme, showing embryoid body formation deficiency and no spontaneous differentiation withdraw LIF. Hnrnpll promotes multiple ES cell preferred-exon skipping during ES cells differentiation, to reduce the ES cells specific isoform and facilitate ES cells exit from pluripotency towards differentiation.

RNA-seq analysis of ES cell populations with different functional potentials in serum/LIF and 2i/LIF, as well as analysis of the transcriptional effect of LIF in ground state (2i) culture conditions.

Project description:We report that ES cells cultured in ground state (2i and 2i/LIF) culture conditions are heterogeneous and show heterogeneus expression of extraembryonic markers. Using a highly sensitive reporter for the endoderm marker Hex we can sort Hex high and low populations from either serum/LIF or 2i/LIF and demonstrate that they have different functional properties. Here we explored the transcriptional basis of these functional differences and noted that Hex low (HV-) and Hex high (HV+) populations showed more distinct expression profiles in 2i/LIF than in serum/LIF. Additionally in 2i/LIF the HV+ population showed an upregulation of extraembryonic markers (such as trophoblast stem cell specific genes) and also imprinted genes compared to the HV- population, which is not observed when these populations are sorted from serum/LIF. We also analysed the transcriptional effect of LIF in 2i by analysing unsorted ES cells cultured in either 2i alone or 2i with LIF. We observed that the addition of LIF led to an upregulation of extraembryonic markers but did not effect the expression of pluripotency genes, other than Klf4. Additionally, the most significantly upregulated genes from 2i/LIF cultured ES cells compared to 2i cultured ES cells showed the greatest correlation to placental tissue when compared to the GNF tissue specific expression database. This analysis, alongside functional experiments, suggested that HV+ ES cells in 2i/LIF corresponded to an extraembryonically primed population of cells and that the addition of LIF supported this population.

Gain of chromatin loops marks the exit from naive pluripotency - ChIP seq for CTCF and Rad21

Project description:ChIP-seq to map the binding sites for CTCF and cohesin subunit Rad21 in the naive mES cells (46C cell line grown in the 2i/LIF condition) and in the neural stem cells (derived from the 46C ES cells using the mono-layer differentiation protocol, grown in the N2B27 medium these cells are Nestin+). The naive mES cells were grown in two different media (fetal bovine serum, FBS and 2i/LIF culture - naive pluripotency conditions) as detailed in the growth protocols.

Single cell analysis of the transcriptomic heterogeneity of ground state pluripotency

Project description:This study aims to investigate the transcriptomic heterogeneity of mouse embryonic stem cells (mES cells) in different culturing conditions with single-cell mRNA-seq technology. Previous studies have reported heterogeneous and differential allelic expression of specific pluripotency genes, e.g. Nanog, in mES cells in different culturing conditions. The fluctuation of gene expression has been linked to drift of pluripotent state. In this study, we will dissect the transcriptome of mouse ES cells culturing in conventiaonal serum/LIF and 2i/LIF conditions at the single-cell level. The usage of a hybrid mouse ES cell line in this study provides additional insight into differential allelic expression in these two culturing conditions. The data generated in this study will shed light on the regulation of pluripotency network.

Transcription profiling by array of mouse wild type and E-cadherin knockout embryonic stem cells grown with or without cytokine leukemia inhibitory factor

Project description:We previously observed that E-cadherin knockout embryonic stem cells do not differentiate in the absence of the cytokine leukemia inhibitory factor (LIF) (Soncin et al., 2009, Stem Cells 27 p2069-2080). This experiment was designed to compare the transcription profile of E-cadherin KO ES cells cultured in the presence and absence of LIF. We also compared E-cadherin KO ES cells with wild type D3 ES cells grown in the presence of LIF.
