(Submitter supplied) Regulation of quiescence is critical for the maintenance of adult hematopoietic stem cells (HSCs). Previous studies by gene disruption during mouse embryonic development have shown that transcription factor gene Prdm16 is important for the generation/maintenance of fetal liver HSCs; however, the underlying mechanisms and the function of Prdm16 in adult HSCs remain unclear. To investigate the role of Prdm16 in adult HSCs, we generated a novel conditional knockout mouse model and deleted Prdm16 in adult mouse hematopoietic system using the interferon inducible Mx1-Cre. more...

(Submitter supplied) Self-renewal is a defining characteristic of stem cells, however the molecular pathways underlying its regulation are poorly understood. Here we demonstrate that conditional inactivation of the Pbx1 proto-oncogene in the hematopoietic compartment results in a progressive loss of long-term hematopoietic stem cells (LT-HSCs) that is associated with concomitant reduction in their quiescence, leading to a defect in the maintenance of self-renewal as assessed by serial transplantation. more...

(Submitter supplied) Hematopoiesis is a series of lineage differentiation programs initiated from hematopoietic stem cells (HSCs) in the bone marrow (BM). To maintain lifelong hematopoiesis, the pool of HSCs is precisely maintained by diverse molecular mechanisms. CCCTC-binding factor (CTCF) is a DNA-binding zinc-finger protein which regulates its target gene expression by organizing higher order chromatin structures. Currently, the role for CTCF in controlling HSC homeostasis is unknown. more...

(Submitter supplied) The transcriptional coactivator Cbp is critical for hematopoietic stem cell (HSC) development. However, its role in adult HSC and the mechanistic detail of Cbp control of HSC function remains unknown. Using conditional deletion of Cbp in the adult HSC compartment, we demonstrate an altered balance between differentiation and self-renewal with gradual loss of phenotypic HSC, differentiation defects in lower compartments and the development of myeloid malignancies. more...

(Submitter supplied) The canonical Wnt signaling pathway has been demonstrated as a critical role in the self-renewal, proliferation and differentiation of Hematopoietic Stem Cells (HSCs), but the functions are indeterminacy in adult HSCs since the different experimental systems using gain- or loss- functions mice models. Low-density lipoprotein receptor-related proteins 5 and 6 (LRP5 and LRP6) are important co-receptors in the canonical Wnt/β-catenin pathway. more...

(Submitter supplied) As Prdm16 deficiency reduces self-renewal potential and depletes neural stem cells in culture we decided to investigate the underlying molecular mechanisms of the neural stem cells depletion in the Prdm16 deficient animals. For the experiment we used Prdm16Gt(OST67423)Lex (Prdm16LacZ) genetrap mice obtained from the NIH Mutant Mouse Regional Resource Center (http://www.mmrrc.org/). We compared the gene expression profiles of uncultured ventricular zone cells from newborn Prdm16LacZ/LacZ (KO), Prdm16LacZ/+(HET), and Prdm16+/+ (WT) mice.

(Submitter supplied) Hematopoietic stem cells (HSCs) enable hematopoietic stem cell transplantation (HCT) through their ability to replenish the entire blood system. Proliferation of HSCs is linked to decreased reconstitution potential, and a precise regulation of actively dividing HSCs is thus essential to ensure long-term functionality. This regulation becomes important in the transplantation setting where HSCs undergo proliferation followed by a gradual transition to quiescence and homeostasis. more...

(Submitter supplied) In blood, the transcription factor C/EBPa is essential for myeloid differentiation and has been implicated in regulating self-renewal of fetal liver hematopoietic stem cells (HSCs). However, its function in adult HSCs is unknown. Here, using an inducible knockout model, we found that C/EBPa deficient adult HSCs underwent a pronounced expansion with enhanced proliferation, characteristics resembling fetal liver HSCs. more...

(Submitter supplied) Hematopoietic stem cells (HSCs) self-renew and generate all blood cells. Recent studies with single-cell transplants and lineage tracing suggest that adult HSCs are diverse in their reconstitution and lineage potentials. However, prospective isolation of these subpopulations has remained challenging. Here, we identify Neogenin-1 (NEO1) as a unique surface marker on a fraction of mouse HSCs labeled with Hoxb5, a specific reporter of long-term HSCs (LT-HSCs). more...

(Submitter supplied) The hematopoietic stem cell (HSC) compartment is heterogeneous, yet our understanding of the identities of different HSC subtypes is limited. Here we show that platelet integrin CD41 (αIIb), currently thought to only transiently mark fetal HSCs, is expressed on an adult HSC subtype that accumulates with age. CD41+ HSCs were largely quiescent and exhibited myeloerythroid and megakaryocyte gene priming, governed by Gata1, whereas CD41- HSCs were more proliferative and exhibited lymphoid gene priming. more...

(Submitter supplied) The polycomb group (PcG) proteins function in gene silencing through histone modifications. They form chromatin-associated multiprotein complexes, termed polycomb repressive complex (PRC) 1 and PRC2. These two complexes work in a coordinated manner in the maintenance of cellular memories through transcriptional repression of target genes. EZH2 is a catalytic component of PRC2 and trimethylates histone H3 at lysine 27 to transcriptionally repress the target genes. more...
