(Submitter supplied) Hematopoietic stem cells (HSCs) are considered a heterogeneous cell population. In an attempt to further resolve the HSC compartment, we characterized a retinoic acid (RA) reporter mouse line. Sub-fractionation of the HSC compartment in RA-CFP reporter mice demonstrated that RA-CFP-dim HSCs were largely non-proliferative and displayed superior engraftment potential in comparison to RA-CFP-bright HSCs. Gene expression analysis demonstrated higher expression of RA-target genes in RA-CFP-dim HSCs, contrasting the RA-CFP reporter expression, but both RA-CFP-dim and –bright HSCs responded efficiently to ATRA in vitro. more...

(Submitter supplied) Quiescence is a fundamental property that protects hematopoietic stem cells’ (HSCs) function throughout life. A subpopulation of deeply quiescent, so-called dormant HSCs (dHSCs) harbors the highest long-term blood repopulation capacity and resides at the top of the hematopoietic hierarchy. However, the mechanisms of HSC dormancy remain elusive, mainly due to the absence of surface markers for dHSCs’ prompt isolation. more...

(Submitter supplied) Hematopoietic Stem Cells (HSCs) originate from the E11.5 aorta-gonads-and mesonephros (AGM) region during development before they migrate to the foetal liver for proliferation and maturation, and finally seed the bone marrow around birth, their final site of residence. In the AGM, HSCs reside within Intra-aortic hematopoietic clusters (IAHC) along with hematopoietic progenitors (HPC). Molecular pathways that determine HSC fate instead of HPCs are still unknown, although inflammatory signalling has been implicated in the development of all blood cells, including NF-κB. more...

(Submitter supplied) Quiescent hematopoietic stem cells (HSCs) are typically dormant, and only a few quiescent HSCs are active. The relationship between “dormant” and “active” HSCs remains unresolved. Here we generated a G0 marker (G0M) mouse line that visualizes quiescent cells. G0M identifies a small population of active HSCs (G0Mlow), which are distinct from dormant HSCs (G0Mhigh), within the conventional quiescent HSC fraction. more...

(Submitter supplied) High-throughput small molecule screening revealed that high concentrations of cytoplasmic calcium ([Ca2+]c) were linked to dormancy of HSCs.To clarify molecular difference between [Ca2+]chigh and [Ca2+]clow cells, we performed RNA-Seq analysis using [Ca2+]chigh and [Ca2+]clow cells.

(Submitter supplied) RNA-seq and ATAC-seq were performed to determine possible downstream molecular mechamisms and the changes in chromatin accessibility in long-term hematopoietic stem cell when TWIST1 was absent following irradiation stress. We found that mitochondrial metabolism pathway was strongly turned on in the Twist1-deficient LT-HSCs upon irradiation stress.

(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) Maintenance of the blood system is dependent on dormant haematopoietic stem cells (HSCs) with long-term self-renewal capacity. Upon injury these cells are induced to proliferate in order to quickly re-establish homeostasis. The signalling molecules promoting the exit of HSCs out of the dormant stage remain largely unknown. Here we show that in response to treatment of mice with interferon-alpha (IFNα), HSCs efficiently exit G0 and enter an active cell cycle. more...

(Submitter supplied) As part of a study of the role of the aryl hydrocarbon receptor (Ahr) in maintenance and senescence of hematopoietic stem cells (HSC), global gene expression profiling was done with HSC isolated from Ahr-knockout and wild-type mice. HSC from young-adult (8 wk old) AhR-KO mice had changes in expression of many genes related to HSC maintenance, consistent with the phenotype observed in aging Ahr-KO mice: decreased survival rate, splenomegaly, increased circulating white blood cells, hematopoietic cell accumulation in tissues, anemia, increased numbers of stem/progenitor and lineage-committed cells in bone marrow, decreased erythroid progenitor cells in bone marrow, and decreased self-renewal capacity of HSC.

(Submitter supplied) Homeostatic hematopoietice stem cells (HSCs) with greater divisional history lose repopulating potential after very few cell divisions. Divisional history overrides both phenotype and immediate quiescence in determining functional activity. In GFP label retaining system GFP is progressively diluted when cells proceed through a cascade of divisions. We used a GFP label retaining system and performed microarray expression analyses to track the changes in the gene expression profile of bone marrow (BM) LSK cells that relates to divisional history during homeostasis.

(Submitter supplied) Using Gfi1b conditional mice, deletion of gfi1b in the hematopietic system was induced by injecting MxCre tg Gfi1bfl/fl mice with pIpC. 30 days after injection, Cd150 pos, Cd 48 neg, Lin neg Sca and c-kit pos stem cells were sortrted from Gfi1bfl/fl and Mxcre tg Gfi1bfl/fl mice and analysed. We used the mouse Affymetrix Gene ST Array.
