(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) 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) Transforming growth factor-β (TGF-β) is considered to play a role in the maintenance of quiescent hematopoietic stem cells (HSCs) in vivo. We asked a question of whether TGF-β could be used to control the cell cycle status of HSCs in vitro. To examine the effect of TGF-β on the HSC function, we used in vitro culture system in which HSCs divide with retention of short- and long-term reconstitution ability. more...

(Submitter supplied) Here, we use single-cell RNA-Seq to examine variation between individual hematopoietic stem and progenitor cells from two mouse strains (C57BL/6 and DBA/2) as they age. We prepared libraries from long-term (LT-HSCs) (LSK CD150+CD48-), short-term hematopoietic stem cells (ST-HSCs) (LSK CD150-CD48-) and multipotent progenitors (MPPs) (LSK CD150+CD48+) from young (2-3 months) and old mice (22 months for C57BL/6 and 20 months for DBA/2). more...

(Submitter supplied) The discovery of significant heterogeneity in the self-renewal durability of adult haematopoietic stem cells (HSCs) has challenged our understanding of the molecules involved in population maintenance throughout life. Gene expression studies in bulk populations are difficult to interpret since multiple HSC subtypes are present and HSC purity is typically less than 50% of the input cell population. Numerous groups have therefore turned to studying gene expression profiles of single HSCs, but again these studies are limited by the purity of the input fraction and an inability to directly ascribe a molecular program to a durable self-renewing HSC. Here we combine single cell functional assays with flow cytometric index sorting and single cell gene expression assays to gain the first insight into the gene expression program of HSCs that possess durable self-renewal. This approach can be used in other stem cell systems and sets the stage for linking key molecules with defined cellular functions.

(Submitter supplied) Cell purification technology combined with whole transcriptome sequencing and small molecule agonist of hematopoietic stem cell self-renewal has allowed us to identify ITGA3 as a surface maker that defines a rare subpopulation of human cells which is highly enriched for stem cell activity in vivo. ITGA3-positive cells (within the EPCR+CD90+CD133+CD34+CD45RA- fraction) exhibit a robust multi-lineage differentiation potential and serial reconstitution in immunocompromised mice. more...

(Submitter supplied) Bone marrow hematopoietic stem cells (HSCs) are crucial to maintain lifelong production of all blood cells. Although HSCs divide infrequently, it is thought that the entire HSC pool turns over every few weeks, suggesting that HSCs regularly enter and exit cell cycle. Here, we combine flow cytometry with label-retaining assays (BrdU and histone H2B-GFP) to identify a population of dormant mouse HSCs (d-HSCs) within the lin(-)Sca1+cKit+CD150+CD48(-)CD34(-) population. more...

(Submitter supplied) Purpose: The goals of this study are to elucidate the underlying mechanism for the activation of HSCs Methods: After wild type (WT) HSCs (CD150+ CD48- EPCR+ Lineage-) were treated with 5-fluorouracil (5-FU), 100 cells of HSCs were sorted. Moreover, after the culture with or without Nifedipien, cultured HSC fraction (CD150+ CD48- EPCR+ c-kit+ Sca-1+ Lineage-) were sorted. These cells were subjected to mRNA sequence using Next-seq (n>3). more...

(Submitter supplied) The Hematopoietically-expressed homeobox transcription factor (Hhex) is important for the maturation of definitive hematopoietic progenitors and B-cells during development. We have recently shown that in adult hematopoiesis, Hhex is dispensable for maintenance of hematopoietic stem cells (HSCs) and myeloid lineages but essential for the commitment of Common Lymphoid Progenitors (CLPs) to lymphoid lineages. more...

(Submitter supplied) Hematopoietic stem cells (HSCs) are now recognized as a heterogeneous population in self-renewing and differentiation capabilities. However, fundamental mechanisms governing the heterogeneity remain uncertain. We here show that special AT-rich sequence-binding protein 1 (SATB1), a global chromatin organizer, is involved in the mechanisms. Analyzing hematological lineage-restricted SATB1 knock out mice proved that SATB1 is indispensable for both self-renewal and normal differentiation of adult HSCs. more...

(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) Hematopoietic stem cell (HSC) transplantation has the potential to cure blood disorders but is limited by donor availability. Hence innovative approaches to engineer HSC are critically needed. HoxB4 over-expression in mouse embryonic stem cell-derived HSC (ESC-HSC) confers long-term engraftment, yet lacks efficient lymphogenesis. Transcriptome comparison of ESC-HSC versus embryo-derived HSC showed that ESC-HSC are deficient in expression programs activated by Notch. more...
