Krüppel-like factor 2 (Klf2) is a DNA-binding transcription factor that regulates embryonic stem cell-specific gene expression. Transcription cofactors such as p300 acetyltransferases and Erk kinases interact with Klf2, providing an additional layer of transcription regulation in embryonic stem cell...
MicroRNAs (miRNAs) are crucial for normal embryonic stem (ES) cell self-renewal and cellular differentiation, but how miRNA gene expression is controlled by the key transcriptional regulators of ES cells has not been established. We describe here a new map of the transcriptional regulatory circuitr...
Transcriptional regulation of developmentally controlled genes is at the heart of differentiation and organogenesis. In this study, we have performed global genomic analyses in murine embryonic stem (ES) cells and in human cells in response to activation signals. We have identified an essential role...

Recent studies have demonstrated that the Ten-eleven translocation (Tet) family proteins can enzymatically convert 5-methylcytosine (5mC) to 5-hydroxymethylcytosine (5hmC). While 5mC has been studied extensively, little is known about the distribution and function of 5hmC. Here we present a genome...
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 Aventis Pharma, Paris, France. Goal of the experiment is the charac...
Embryonic stem cells have a unique regulatory circuitry, largely controlled by the transcription factors Oct4, Sox2 and Nanog, which generates a gene expression program necessary for pluripotency and self-renewal (Boyer et al. 2005; Loh et al. 2006; Chambers et al. 2003; Mitsui et al. 2003; Nichols ...
Unlike mouse embryonic stem (ES) cells, which are closely related to the inner cell mass, human ES cells appear to be more closely related to the later primitive ectoderm. For example, human ES cells and primitive ectoderm share a common epithelial morphology, growth factor requirements, and the po...
This experiment is part of the FunGenES project (FunGenES - Functional Genomics in Embryonic Stem Cells partially funded by the 6th Framework Programme of the EuropeanUnion, http://www.fungenes.org). The experiment was conducted at University of Cologne, Cologne, Germany. Goal of the experiment is a...
3 different ES cell lines were compared in order to determine whether there are significant expression profile differences between ES cell lines, or whether the constraints of maintaining pluripotency in culture force a similar expression profile on cell lines derived from disparate sources. Our res...
