Mouse embryonic stem cells (ESCs) can differentiate into a wide range - and possibly all cell types in vitro, and thus provide an ideal platform to study systematically the action of transcription factors (TFs) in cell differentiation. Previously, we have generated and analyzed 137 TF-inducible mouse ESC lines. As an extension of this "NIA Mouse ESC Bank," we generated and characterized 48 additional mouse ESC lines, in which single TFs in each line could be induced in a doxycycline-controllable ...[more]

Project description:Here we report the generation of 84 mouse ES cell lines with doxycycline-controllable transcription factors (TFs) which, together with the previous 53 lines, cover 7 - 10% of all TFs encoded in the mouse genome. Global gene expression profiles of all 137 lines after the induction of TFs for 48 hrs can associate each TF with the direction of ES cell differentiation, regulatory pathways, and mouse phonotypes. These cell lines and microarray data provide the building blocks for a variety of future biomedical research applications as a community resource. This set of data uses Universal Mouse Reference on the Cy5 channel. ES cells (passage 25) were cultured in the standard LIF+ medium with Dox+ on a gelatin-coated dish through the experiments. Cells from each cell line were split into 6 wells and the media was changed 24 hr after cell plating: 3 wells with Dox+ medium, and 3 wells with Dox- medium to induce transgenic TFs. Dox was removed via washing 3 times with PBS at 3 hour intervals. Total RNA was isolated by TRIzol (Invitrogen) after 48 hr, and two replications were used for real time qPCR and for microarray hybridization. RNA samples were labeled using the Low RNA Input Fluorescent Linear Amplification Kit (Agilent). For most TFs, we hybridized a Cy3-CTP labeled sample from Dox- medium together with a Cy5-CTP labeled sample from Dox+ medium. But for 7 TFs, we labeled samples from Dox- and Dox+ with Cy3, and hybridized them independently with a Cy5-labeled reference target, which is a mixture of Stratagene Universal Mouse Reference RNA and MC1 cells RNA (this method requires a double number of arrays). Analysis showed that both methods produce results of comparable quality.

Project description:A network of transcription factors (TFs) determines cell identity, but identity can be altered by overexpressing a combination of TFs. In principle, this opens the possibility of achieving one of the goals of regenerative medicine generating the desired differentiated cells from pluripotent stem cells, such as embryonic stem (ES) cells and induced pluripotent stem (iPS) cells. However, choosing and verifying combinations of TFs for specific cell differentiation has been daunting due to a large number of possible combinations of ~2,000 TFs. Here we report an unbiased systematic approach identifying individual TFs that can direct efficient and rapid specific lineage differentiation. We start from a correlation matrix of global gene expression responses to the induction of single TFs and global gene expression profiles of a variety of tissues and organs. Based on the correlation matrix, we select TFs as examples and show that their overexpression differentiates ES cells into cells of specific organs, as predicted: Sfpi1 for blood cells, Hnf4a or Foxa1 for hepatocytes, and Ascl1 for neurons. Furthermore, we show that transfection of synthetic mRNAs of Sfpi1, Hnf4a, or Ascl1 generate correspondingly specific target cells. These results demonstrate both the wide-ranging utility of this approach to identify potent TFs for cell differentiation, and also the unanticipated capacity of single TFs to directly guide differentiation to specific lineage fates. Previously, we generated the global gene expression profiles obtained by overexpressing single TFs using the NIA mouse ES cell bank, which consists of 137 mouse ES cell lines carrying a doxycycline-regulatable TF. We then generated the correlation matrix by comparing TF-induced gene expression profiles and the expression profiles of a variety of cell types. TFs predicted by the correlation matrix for specific cell differentiation were selected and subjected to the detailed differentiation assays. ES cell lines were cultured in the GMEM with 1% FBS, 10% knockout serum (invitrogen), and LIF (Millipore). To induce differentiation, ES cell lines were cultured in the differentiation medium (DM) [(alpha minimal essential medium, aMEM) supplemented with 10% fetal calf serum and 5 × 10–5 M 2-mercaptoethanol] with or without doxycycline (1 g/ml). The following organ-specific cell culture media were also used: StemPro-34 Serum Free Media (invitrogen) for blood cells, Hepatocyte culture media kit (BD Biosciences) for hepatocytes, and NeuroCult differentiation kit (StemCell Technologies Inc) for neurons.

Project description:To decipher the structure and behaviors of the transcription factor (TF) network, we created 50 permanent mouse ES cell lines, in each of which one of the 50 transcription factors tagged with FLAG, is inserted into the doxycycline (dox)-repressible ROSA26 locus. Expression profiling reveals Cdx2 as the most potent inducer of transcriptome perturbation in ES cells, followed by Esx1, Sox9, Tcf3, Klf4, and Gata3. Immunoprecipitation (IP) with a FLAG-antibody in Cdx2-induced ES cells, identifies NuRD in CDX2-associated protein complexes; and chromatin-IP-sequencing identifies CDX2-binding sites predominantly in genes up-regulated by CDX2. Compendium analyses of Cdx2- and the other TF-inducible ES cells suggest a central role of the POU5F1/SOX2/NANOG protein complex in a swift-acting control mechanism to down-regulate a common set of genes at the beginning of multi-lineage ES cell differentiations. These ES cell lines will be a valuable resource to study biological networks in ES cells and mice.

Cells were electroporated with linearlized pMWROSATcH and selected by hygromycine B. Knock-in for ROSA-TET locus in ES[MC1R(20)] cells was confirmed by southern blotting. For exchange vectors, PCR amplified ORFs were subcloned into pZhcSfi that was modified to express His6-FLAG tagged protein and puromycin resistant gene. ES[MC1R(20)] cells (passage 17) cultured on feeder cells were co-transfected with sequence verified exchange vector and pCAGGS-Cre and selected by puromycin in the presence of doxycycline. Isolated clones were tested for Venus expression, hygromycin B susceptibility, transgene RNA expression, genotyping for Cre mediated integration, karyotyping, western blotting using anti-FLAG antibody (Sigma-Aldrich) and mycoplasma contamination. ES cells (passage 25) were plated onto gelatin-coated dish. Doxycycline was removed through washing 3 times with PBS at 3 hours intervals. Total RNA was isolated by TRIzol (Invitrogen) after 2 days. Cy3-CTP labeled sample targets were prepared with total RNA by Low RNA Input Fluorescent Linear Amplification Kit (Agilent). Cy5-CTP labeled reference target was produced from mixture of Stratagene Universal Mouse Reference RNA and MC1 cells RNA.

Project description:To decipher gene regulatory networks, we used systematic suppression of 97 transcription factors (TFs) and 7 other genes with shRNA in mouse embryonic stem (ES) cells, followed by global gene expression profiling. Meta-analysis of these data together with the earlier data obtained by the induction of 50 TFs and the existing genome-wide data on TF binding sites identified the sets of regulated target genes for 23 TFs. Principal component analysis shows different roles of two groups of TFs that are active in ES cells: Pou5f1 and Sox2 support the expression of their target genes and prevent the upregulation of trophectoderm-related genes, whereas Esrrb, Sall4, Nanog, Gbx2, Grhl2, Mtf2, Aff1, Tcfap4, and Cdc5l support the expression of targets of Esrrb, including glycolysis genes, and prevent upregulation of targets of Trp53 and Polycomb TFs. If TFs from the second group are downregulated while Pou5f1 and Sox2 are still active, then the cell state changes towards epiblast lineages. Sequences for shRNA were designed to target 3 untranslated region of genes (Supplementary Table S8). Gene expression change was checked with real time qPCR (Supplementary Figure S7) and Westerm blot. ES cells (ES[MC1R(20)], passage 20) were cultured without feeders and were co-transfected with 1.6 g of shRNA expression vector and 0.4 g of pPyCAG-EGFP-IP carrying expression cassettes for puromycin resistant genes and EGFP using Effectene (Qiagen). Transfected cells were cultured in presence of 1.5 g/ml of puromycin and were harvested at 72 h after transfection. Mock cells were treated with transfection reagent without DNA and cultured in the absence of puromycin. Experiments were done in 3 replications with 2 of them used for gene expression profiling with microarrays. Total RNA was isolated by TRIzol (Invitrogen) after 2 days. Cy3-CTP labeled sample targets were prepared with total RNA by Low RNA Input Fluorescent Linear Amplification Kit (Agilent). Cy5-CTP labeled reference target was Stratagene Universal Mouse Reference RNA. Note that the processed data in the paper, which is also attached as GSE26520_Table_data.txt.gz, is slightly different from the values columns in each sample. The original processed data are normalized with a batch method, as the new batches of arrays added in the set. The value columns in this submission reflect full normalization as described in the data processing fields in each sample.

Project description:BACKGROUND: In addition to determining static states of gene expression (high vs. low), it is important to characterize their dynamic status. For example, genes with H3K27me3 chromatin marks are not only suppressed but also poised for activation. However, the responsiveness of genes to perturbations has never been studied systematically. To distinguish gene responses to specific factors from responsiveness in general, it is necessary to analyze gene expression profiles of cells responding to a large variety of disturbances, and such databases did not exist before. RESULTS: We estimated the responsiveness of all genes in mouse ES cells using our recently published database on expression change after controlled induction of 53 transcription factors (TFs) and other genes. Responsive genes (N = 4746), which were readily upregulated or downregulated depending on the kind of perturbation, mostly have regulatory functions and a propensity to become tissue-specific upon differentiation. Tissue-specific expression was evaluated on the basis of published (GNF) and our new data for 15 organs and tissues. Non-responsive genes (N = 9562), which did not change their expression much following any perturbation, were enriched in housekeeping functions. We found that TF-responsiveness in ES cells is the best predictor known for tissue-specificity in gene expression. Among genes with CpG islands, high responsiveness is associated with H3K27me3 chromatin marks, and low responsiveness is associated with H3K36me3 chromatin, stronger tri-methylation of H3K4, binding of E2F1, and GABP binding motifs in promoters. CONCLUSIONS: We thus propose the responsiveness of expression to perturbations as a new way to define the dynamic status of genes, which brings new insights into mechanisms of regulation of gene expression and tissue specificity Inhibitors of cell signaling are known to support the pluripotent state of embryonic stem cells (Ying et al. 2008, Nature 453, 519-523, PMID: 18497825). To characterize the effect of inhibitors on the gene expression we treated B6R(5) mouse ES cells (C57BL/6 strain) with FGFR inhibitor PD173074 (100 uM), MEK inhibitor PD98059 (25 uM),and GSK-3 inhibitor BIO (2 uM) 24 hr after plating. Cells were grown without feeders on gelatin coated, 6-well plates, 100,000 cells/well (10^4 cells/cm2), in complete ES medium at 37 0C; 5% CO2. Medium was changed daily. Inhibitors dissolved in DMSO were added 24 hr after plating and cells were harvested 48 hr after treatment (72 hr after plating). Control cells were treated with DMSO.

Project description:Controlled induction of individual transcription factors (TFs) in embryonic stem cells (ESCs) with subsequent global gene expression profiling is a promising approach for identification of downstream genes regulated by these TFs in a relatively promiscuous epigenetic background. Here we generated and characterized mouse ESCs clones with 49 doxycycline-controllable TFs as a continuation of the NIA Mouse ESC Bank project. Together with the previous clone libraries, the project now comprises 186 TFs (ca. 10% of all TFs in the genome). Induction of individual TFs shifts the transcriptome towards specific differentiation fates (e.g., neural for Myt1, St18; fibroblasts and osteoblasts for Pitx1, Pitx2, Barhl2, and Lmx1a; thymocytes for Myb; lymph nodes and spleen for Etv2 and Plac1, and ovary for Pitx1, Pitx2, and Dmrtc2). Gene set enrichment analysis for expression profile change after induction of TFs provides additional information on the functions and phenotypes associated with these TFs. These data could facilitate methods for generating various types of cells in regenerative medicine as well as ameliorating pathogenic phenotypes in gene therapy.
