(Submitter supplied) We performed RNA sequencing analyses of adult mouse bone marrow endothelial cells. Especially, we investigated gene expression profiling of endothelial cells before and after lethal irradiation or hematopoietic cell depletion. We also analyzed mouse bone marrow endothelial cell subtypes, Apln+ and diaphyseal endothelial cells. Whole bone marrow cells, lineage negative hematopoietic stem and progenitor cells, Lin- Sca1+ cKit+ cells were used as controls for the differential gene expression analyses.

(Submitter supplied) Erg is an ETS family transcription factor frequently overexpressed in human leukemias and has been implicated as a key regulator of hematopoietic stem cells (HSCs). However how Erg controls normal hematopoiesis, particularly at the stem cell level, remains poorly understood. Using homologous recombination, we generated an Erg knockdown allele (Ergkd) in which Erg expression can be restored upon Cre-mediated excision of a Stopper cassette. more...

(Submitter supplied) Our data mark GIP as a beneficial immunoregulator during obesity and suggest a novel untapped therapeutic potential for specific targeted GIP analogs. Emerging studies suggest that glucose-dependent insulin tropic polypeptide (GIP) affect obesity-associated inflammation. Yet, whether GIP can directly regulate immune cell activity and the respective metabolic consequences remained unknown. Here, we targeted GIP-receptor-deficiency to immune cells using bone marrow (BM) chimerism approach and the reconstituted chimeric mice were subjected to a high fat diet (HFD) regimen. more...

(Submitter supplied) We generated a humanized mouse model of oncogene-induced senescence in hematopoietic stem and progenitor cells by expressing the activated oncogene BRAF-V600E. Mice succumbed to bone marrow failure and multi-organ dissemination of aberrant macrophages and dendritic cells. We observed a myeloid-restricted hematopoiesis,and uncovered the activation of a senescence program, characterized by growth arrest and senescence-associated secretory phenotype (SASP), which involved also non-mutated bystander cells.

(Submitter supplied) How a single oncogenic RAS impacts non-transformed hematopoietic progenitor cells (HPCs) remains largely unknown. We therefore investigated how a monoallelic KRAS mutation (G13C) affected HPCs utilizing induced pluripotent stem cells (iPSCs) derived from two unrelated patients with RAS-associated autoimmune lymphoproliferative syndrome-like disease (RALD).

(Submitter supplied) Hematopoietic stem cells (HSCs) inhabit distinct microenvironments within the adult bone marrow (BM) that govern the delicate balance between HSC quiescence, self-renewal, and differentiation. It has been suggested that quiescent HSCs localize adjacent to BM arteriole endothelial cells in a significant and non-random distribution. This data suggests that the arteriole BM vascular niche may be the primary HSC niche. more...

(Submitter supplied) Fetal hematopoietic stem and progenitor cells (HSPCs) migrate from fetal liver (FL) to bone marrow (BM) around birth. While adult BM HSPCs and their extrinsic regulation is well studied, little is known about the composition, function, and extrinsic regulation of the first HSPCs to enter the BM. Here, we show that HSPCs colonize multiple fetal bones by E15.5, shift from an MPP2 to an MPP3/4-dominant phenotype by birth, and display little function until E18.5, relative to their FL counterparts. We establish a transcriptional atlas of single perinatal HSPCs, and their putative BM niches, from E15.5 through P0 and show that early fetal BM (FBM) lacks HSPCs with intrinsic stem cell programs and niche cells supportive of HSPCs. In contrast, stem cell programs are preserved in neonatal BM HSPCs, which engage with a niche expressing HSC supportive factors distinct from those seen in adult BM (i.e., IGF).

(Submitter supplied) ETS Variant 6 (ETV6) encodes an essential transcriptional repressor abundantly expressed in hematopoietic stem and progenitor cells (HSPCs), where it is required for adult hematopoiesis. Heterozygous pathogenic germline ETV6 variants are associated with Thrombocytopenia 5 (T5), a poorly-understood genetic condition predisposing to thrombocytopenia and hematologic malignancies. To elucidate how germline ETV6 variants impact the HSPC compartment and contribute to disease, we generated a knock-in mouse harboring an Etv6R355X loss-of-function variant, which represents the mouse equivalent to the T5-associated variant ETV6R359X. more...

(Submitter supplied) U2AF1 is involved in the recognition of the 3’ splice site during pre-mRNA splicing. Mutations in U2AF1 are frequently observed in myelodysplastic syndromes. However, the role of wild-type U2AF1 in normal hematopoiesis has remained elusive. Using a novel conditional U2af1 knockout allele, we have found that deletion of U2af1 results in profound defects in hematopoiesis characterized by pancytopenia, ablation of hematopoietic stem/progenitor cells (HSPC) leading to bone marrow failure and early lethality in mice. more...

(Submitter supplied) Aging is associated with functional decline of hematopoietic stem cells (HSC) as well as an increased risk of myeloid malignancies. We performed an integrative characterization of epigenomic and transcriptomic changes, including single-cell RNA-seq, during normal human aging. Lineage-CD34+CD38- cells (HSC-enriched, HSCe) undergo age-associated epigenetic reprogramming consisting of redistribution of DNA methylation and reductions in H3K27ac, H3K4me1 and H3K4me3. more...

(Submitter supplied) We show that regular physical activity decreases hematopoietic stem and progenitor cell (HSPC) proliferation in mice and results in reduced leukocyte production. Effects in HSPC last due to exercise-induced changes in the HSPC epigenome, as assessed by ATAC-seq, which remained for weeks after running ceased.
