Analysis of Bmi1 transduced CCE embryonic stem cells (ESC) and CCE ESC differentiated by embryoid body assay. Bmi1 is essential for maintaining the pool of adult stem cells. Results provide insight into role of Bmi1 in ESC-derived hematopoietic cell transition from pluripotency to differentiation.

(Submitter supplied) Bmi1 is a component of the Polycomb-repressive complexes (PRC) and essential for maintaining the pool of adult stem cells. PRC are key regulators for embryonic development by modifying chromatin architecture and maintaining gene repression. To assess the role of Bmi1 in pluripotent stem cells and upon exit from pluripotency during differentiation, we studied forced Bmi1 expression in mouse embryonic stem cells (ESC). more...

(Submitter supplied) Bmi1 is a component of polycomb repressive complex 1 and its role in the inheritance of the stemness of adult somatic stem cells has been well characterized. Bmi1 maintains the self-renewal capacity of adult stem cells, at least partially, by repressing the Ink4a/Arf locus that encodes a cyclin-dependent kinase inhibitor, p16Ink4a, and a tumor suppressor, p19Arf 14. Deletion of both Ink4a and Arf in Bmi1-deficient mice substantially restored the defective self-renewal capacity of HSCs and neural stem cells.

(Submitter supplied) Bmi1 is a protein member of PRC1 and plays a major role in the maintenance of gene repression. We are studying the role of Bmi1 in the context of hematopoietic stem cell aging. We used microarray to study the gene expression profile of LSK cells in relation to the knocking-out of Bmi1 in vivo

(Submitter supplied) We have previously shown that conditional overexpression of Bmi1 in NSC increases their proliferation both in the developing neocortexand in the postnatal brain (Yadirgi et al. 2011). However, during embryonic development, increased and ectopic proliferation induced by overexpression of Bmi1 in progenitors committed toward a neuronal lineage triggered apoptosis, leading eventually to a reduced overall brain size (Yadirgi et al. more...

(Submitter supplied) Primitive neural stem cells (NSCs) could be derived from pluripotent mouse embryonic stem (ES) cells, and then differentiate into definitive-type neural stem cells which resemble NSCs obtained from the central nervous system. Hence, primitive NSCs define an early stage of neural induction and provide a model to understand the mechanism that controls initial neural commitment. In this study, we performed microarray assay to analyze the global transcriptional profiles in mouse ES cell-derived primitive and definitive NSCs and to depict the molecular changes during the multi-staged neural differentiation process.

(Submitter supplied) Polycomb repressive complex 2 (PRC2) trimethylates lysine 27 of histone H3 (H3K27me3), which regulates gene expression and controls diverse biological transitions in development, embryonic stem cell (ESC) differentiation, and cancer. Here we show that Polycomb-like 3 (Pcl3) is a component of PRC2 that promotes H3K27 trimethylation in ESCs. Chromatin immunoprecipitation and sequencing (ChIP-seq) revealed that Pcl3 co-localizes and recruits Suz12 to CpG islands. more...

(Submitter supplied) Bone marrow mesenchymal stromal cells (MSCs) that express high levels of stem cell factor (SCF) and CXC chemokine ligand 12 (CXCL12) are one crucial component of the hematopoietic stem cell (HSC) niche. While the secreted factors produced by MSCs to support HSCs have been well described, little is known regarding the transcriptional regulators controlling the cell fate of MSCs and thus indirectly maintaining HSCs. more...

(Submitter supplied) In vertebrates, GATA2 is a master regulator of hematopoiesis and is expressed throughout embryo development and in adult life. Although the essential role of GATA2 for the onset of mouse hematopoiesis is well established, its involvement during early human hematopoietic development is not clear. By combining time-controlled overexpression of GATA2 with genetic knockout experiments, we found that GATA2, at the mesoderm specification stage, promotes the generation of hemogenic progenitors and their further differentiation to hematopoietic progenitor cells, while negatively regulating cardiac differentiation. more...

(Submitter supplied) Polycomb group (PcG) proteins comprise a large group of evolutionary conserved factors with essential roles for embryonic development and adult stem cell function. PcG proteins constitute two main multiprotein polycomb repressive complexes (PRC1 and PRC2) that operate in a hierarchical manner to silence gene expression. Functionally distinct PRC1 complexes are defined by Polycomb group RING finger protein (PCGF) paralogs. more...

(Submitter supplied) Recently, we identified a population of Oct4+Sca-1+Lin-CD45- very small embryonic-like stem-cells (VSELs) in adult tissues. Open chromatin structure of pluripotency genes and genomic imprinting-related epigenetic mechanisms maintain pluripotency and quiescence of VSELs, respectively. However, global transcriptome signature of this rare stem-cell population remains elusive. Here, we demonstrate by genomewide gene-expression analysis with a small number of highly purified murine bone-marrow (BM)-derived VSELs, that Oct4+ VSELs i) express a similar, yet nonidentical, transcriptome as embryonic stem-cells (ESCs), ii) up-regulate cell-cycle checkpoint genes, iii) down-regulate genes involved in protein turnover and mitogenic pathways, and iv) highly express Ezh2, a polycomb group protein. more...

The activities of these genes are coordinately reversed during differentiation. The changes in the transcriptome upon conditional KAP1 knockout in ES cells overlapped with the changes during embryoid body formation. KAP1 repressed differentiation-inducible genes and derepressed pluripotency-associated genes in ES cells. more...
