Effect of BMP4 and noggin on gene expression in murine R1 ES cells

ABSTRACT: To confirm that the SMAD1/5- and SMAD4-associated genes are direct transcriptional regulators in mESCs in response to BMP, we treated undifferentiated R1 ES cells with BMP4 or with the BMP4 antagonist noggin, which can inhibit BMP signaling effectively for 4 h. Undifferentiated R1 ES cells were treated for 4 h with BMP4 or with the BMP4 antagonist noggin, which can inhibit BMP signaling effectively. Untreated R1 ES cells served as the control.

Embryonic stem (ES) cells are under precise control of both intrinsic self-renewal gene regulatory network and extrinsic growth factor-triggered signaling cascades. How external signaling pathways connect to core self-renewal transcriptional circuits is largely unknown. To probe this, we chose BMP signaling, which is previously recognized as a master control for both self-renewal and lineage commitment of murine ES cells. Here, we mapped target gene promoter occupancy of SMAD1/5 and SMAD4 on a g ...[more]

Matrix metalloproteinase-3 mediates cardiac differentiation of mouse embryonic stem cells

Project description:Recently, it was shown that the Bmp antagonist Noggin could strongly induce cardiomyocyte differentiation by transient treatment of undifferentiated ES cells. In order to determine how Noggin may induce cardiac differentiation, we compared differentially expressed genes during Noggin treatment of ES cells using microarray analysis and found that matrix metalloproteinase (Mmp)-3 is the only gene whose expression is increased by Noggin treatment. Keywords: embryonic stem cells, cardiac differentiation, matrix metalloproteinase-3, Noggin

Transcription profiling of mouse wild type R1 and cells expressing Pax4 following induction of pacreatic differentitation

Project description:This experiment is part of the FunGenES project (FunGenES - "Functional Genomics in Embryonic Stem Cells" partially funded by the 6th Framework Programme of the European Union, http://www.fungenes.org). The experiment was conducted at the Leibniz Institute of Plant Genetics and Crop Plant Research (IPK, Gatersleben, Germany) The goal of the experiment is to optimize existing differentiation protocols for endoderm differentiation of ES cells to efficiently generate optimal levels of pancreatic cell types. To characterize potential pancreatic progenitors during the process of induced pancreatic differentiation, wild type R1 cells and R1 cells stably expressing the pancreatic control gene Pax4, RNA samples of undifferentiated cells, pancreatic precursor and differentiated cells were prepared.

The Pitx2:miR-200c/141:noggin pathway regulates BMP signaling and ameloblast differentiation

Project description:The mouse incisor is a remarkable tooth that grows throughout the animal’s lifetime. This continuous renewal is fueled by epithelial stem cells that give rise to ameloblasts, which generate enamel, and little is known about the function of specific miRNAs in this process. Here we describe the role of a novel Pitx2:miR-200c/141:Noggin regulatory pathway in dental epithelial cell differentiation. miR-200c repressed noggin, an antagonist of Bmp signaling. Pitx2 expression caused an up-regulation of miR-200c and chromatin immunoprecipitation (ChIP) assays revealed endogenous Pitx2 binding to the miR-200c/141 promoter. A positive feedback loop was discovered between miR-200c and Bmp signaling. miR-200c/141 induced expression of E-cadherin and the dental epithelial cell differentiation marker, amelogenin. In addition, miR-203 expression was activated by endogenous Pitx2 and targeted the Bmp antagonist Bmper to further regulate Bmp signaling. miR-200c/141 knockout mice showed defects in enamel formation with decreased E-cadherin and amelogenin expression and increased noggin expression. Our in vivo and in vitro studies reveal a multistep transcriptional program involving the Pitx2:miR-200c/141:Noggin regulatory pathway that is important in epithelial cell differentiation and tooth development.

FGF2 sustains NANOG and switches the outcome of BMP4 induced human embryonic stem cell differentiation

Project description:NANOG has emerged as a central gatekeeper of pluripotency. Here we show that as human embryonic stem (ES) cells exit the pluripotent state, NANOG can play a key role in determining lineage outcome. It has previously been reported that BMPs can induce differentiation of human ES cells into extraembryonic lineages. Here we report that FGF2 switches BMP4 induced differentiation outcome to mesendoderm, characterized by the uniform expression of T (brachyury) and other primitive streak markers. Blocking the MEK-ERK pathway either by chemical inhibitors or by an ERK-specific phosphatase (DUSP6) blocks the FGF2-mediated lineage switch. Active MEK-ERK signaling prolongs NANOG expression during BMP-induced differentiation. Forced NANOG expression results in FGF independent BMP4 induction of mesendoderm, and knockdown of NANOG greatly reduces T induction. Together, our results demonstrate that FGF2 signaling switches the outcome of BMP4 induced differentiation of human ES cells by maintaining NANOG levels through the MEK-ERK pathway. There are three sets of expression data. Set 1 (14 samples) is 5day human ES cells (H1) differentiated with different concentrations of BMP4, in the presence or absence of FGF2. Set 2 (14 samples) is 50ng/mL of BMP4 induced H1 cells differentiation time course, with or without FGF2. Set 3 (22 samples) is 5ng/mL of BMP4 induced H1 cells differentiation time course, with or without FGF2.

Expression data from Rad21 knock-down in ES cells

Project description:The Cohesin complex has recently been described to regulate gene expression. We wanted to determine the gene expression profile specific in mouse ES cells after depletion of the Cohesin subunit Rad21. We used microarrays to detail the global programme of gene expression underlying depletion of Rad21 and identified distinct early development related genes up-regulated and many pluripotency related genes downregulated. Rad21 was depleted in R1/E ES cells for 48h using esiRNAs against Rad21. An esiRNA against non-targeting Luciferase was used as a negative control

Effects of Brca1 knock-down on Ezh2 targeting

Project description:The Polycomb repressive complex 2 (PRC2) is important for the maintenance of stem cell pluripotency and suppression of cell differentiation by promoting histone H3 lysine 27 trimethylation (H3K27me3) and silencing expression of genes regulating differentiation. Here we show decreased expression of BRCA1 promotes EZH2 re-targeting genome wide and enhances H3K27me3 levels at PRC2 target loci in mouse ES cells. R1 mouse ES cells were transfected with control siRNA and Brca1 specific siRNA. At 48h after transfection, cells were harvested and subjected to ChIP assay with Ezh2 antibody. Brca1 wild-type (AB2.2) and Brca1 deficient (PL2F8) mouse ES cells were harvested and subjected to ChIP assay with Ezh2 antibody. Fragmented DNA obtained from ChIP assay was repaired by DNA Terminator End Repair Kit (Lucigen Corporation, Middleton, WI) and purified by QIAquick PCR purification kit. Then two unidirectional linkers JW102 and JW103 were annealed and ligated to the blunt ends DNA at 16M-BM-0C overnight. The purified products were amplified to 2 M-NM-<g by LM-PCR. NimbleGen Mouse ChIP 3x720K RefSeq Promoter Array (Roche) were used for the hybridization. Relative enrichments were calculated by dividing the normalized level of ChIP DNA to that of input DNA at corresponding locus. Labeling, hybridization and washing were carried out according to manufacturerM-bM-^@M-^Ys instructions. Experiments in AB2.2 and PL2F8 cells were performed in duplicate.
