(Submitter supplied) Hematopoiesis occurs within a unique bone marrow (BM) microenvironment which consists of various niche cells, cytokines, growth factors and extracellular matrix components. These multiple components directly or indirectly regulate the maintenance and differentiation of hematopoietic stem cells (HSCs). Here we report that Bap1 in BM mesenchymal stromal cells (MSCs) is critical for the maintenance of HSCs and B lymphopoiesis. more...

(Submitter supplied) Zinc finger protein 521 (ZFP521), a DNA-binding protein containing 30 Krüppel-like zinc fingers, has been implicated in the differentiation of multiple cell types, including hematopoietic stem and progenitor cells (HSPC) and B lymphocytes. Here, we report a novel role for ZFP521 in regulating the earliest stages of hematopoiesis and lymphoid cell development through soluble microenvironmental proteins. more...

(Submitter supplied) Signal transducer and activator of transcription 5 (STAT5a and STAT5b) are intrinsically critical for normal hematopoiesis but are also expressed in stromal cells. However, hematopoiesis-supporting stromal function has not been reported. Here, STAT5ab knockout (KO) was generated with a variety of bone marrow hematopoietic and stromal Cre transgenic mouse strains. Pan-hematopoietic deletion with Vav1-Cre was the positive control for loss of multipotent hematopoietic function but surprisingly dysregulated niche factor mRNA expression and deleted STAT5ab in CD45neg cells. more...

(Submitter supplied) Hematopoietic stem cells (HSCs) primarily reside in the bone marrow where signals generated by stromal cells regulate their self-renewal, proliferation, and trafficking. Endosteal osteoblasts and perivascular stromal cells including endothelial cells3, CXCL12-abundant reticular (CAR) cells, leptin-receptor positive stromal cells, and nestin-GFP positive mesenchymal progenitors have all been implicated in HSC maintenance. more...

(Submitter supplied) The bone is essential for locomotion, calcium storage and harboring the hematopoietic stem cells (HSCs) that supply the body with mature blood cells throughout life. HSCs reside at the interface of the bone and bone marrow (BM), where active bone remodeling takes place. Although the cellular components of the BM niche have been characterized, little is known about its epigenetic regulation. Here we find that the histone methylation regulator PTIP (Pax interaction with transcription-activation domain protein-1) is required to maintain the integrity of the BM niche by promoting osteoclast differentiation. more...

(Submitter supplied) It has been shown previously that endothelial cells and LepR+ stromal cells are the main sources of SCF in vivo in the mouse bone marrow. We tested whether SCF from endothelial cells and/or LepR+ stromal cells is important for the maintenance of hematopoietic progenitors and erythroid progenitors in mouse bone marrow by conditional deletion of Scf from these two cell types. We discovered that Scf deletion from LepR+ stromal cells, but not endothelial cells, reduced the numbers of hematopoietic progenitors and erythroid progenitors in mice. more...

(Submitter supplied) To identify target genes of mutant ASXL1 and BAP1 in hematopoietic cells, we performed RNA-seq using murine c-kit positive cells transduced with ASXL1-MT (MT) or ASXL1-MT-K351R (KR) together with vector or BAP1. Method：Murine c-kit positive bone marrow cells were transduced with ASXL1-MT (MT) or ASXL1-MT-K351R (KR) (coexpressing blastcidin resistant gene) together with vector or BAP1 (coexpressing puromycin resistant gene). more...

(Submitter supplied) Increased number of circulating myeloid cells is a hallmark of several cancers, however it remains unclear how primary tumors impact on myelopoiesis. Here we show that non-metastatic breast tumors remotely instruct the fate of long-term hematopoietic stem cell (HSCLT) in the bone marrow. We found that HSCLT from tumor bearing mice acquire a myeloid bias persisting upon primary and secondary HSCLT transfer in lethally-irradiated tumor-free animals. more...

(Submitter supplied) Considerable information has accumulated about components of bone marrow that regulate survival, self-renewal and differentiation of hematopoietic cells. We have now studied Wnt signaling in that context, assessing influences on human and murine hematopoiesis. Microarray, PCR and staining experiments revealed that OP9 acquired osteoblastic characteristics while down-regulating some features associated with mesenchymal stem cells. more...

(Submitter supplied) Non-hematopoietic cells contribute essentially to hematopoiesis. However, heterogeneity and spatial organization of these cells in human bone marrow remain largely uncharacterized. We used single-cell RNA sequencing (scRNA-Seq) to profile 29,325 non-hematopoietic cells and discovered nine transcriptionally distinct subtypes. We simultaneously profiled 53,417 hematopoietic cells and predicted their interactions with non-hematopoietic subsets. more...

(Submitter supplied) Here, we investigate the role of Early B-cell factor 1 (EBF1) in MSCs to support hematopoiesis. Ebf1 deletion in Cxcl12-abundant reticular (CAR) cells and PDGFRα+Sca1+CD45-CD31-Lin- (PαS) cells in the bone marrow decreases the numbers of HSCs and myeloid cells. Single cell and bulk transcriptome analysis, combined with analysis of chromatin accessibility in EBF1-deficient MSCs revealed decreased expression of adhesion molecules and altered niche composition. more...

Here, we investigate the role of Early B-cell factor 1 (EBF1) in MSCs to support hematopoiesis. Ebf1-/- MSCs have reduced mesenchymal lineage potential. Ebf1 deletion in Cxcl12-abundant reticular (CAR) cells and PDGFRα+Sca1+CD45-CD31-Lin- (PαS) cells in the bone marrow decreases the numbers of HSPCs and myeloid cells. more...

(Submitter supplied) We report the genome wide binding sites of BAP1, HCF1 and OGT in bone marrow derived macrophages. De-ubiquitinating enzyme BAP1 is mutated in a hereditary cancer syndrome with increased risk of mesothelioma and uveal melanoma. Somatic BAP1 mutations occur in various malignancies. We show that mouse Bap1 gene deletion is lethal during embryogenesis, but systemic or hematopoietic-restricted deletion in adults recapitulates features of human myelodysplastic syndrome (MDS). more...
