(Submitter supplied) Adult hematopoietic stem cells (HSCs) reside primarily in bone marrow. However, hematopoietic stresses such as myelofibrosis, anemia, pregnancy, infection or myeloablation can mobilize HSCs to the spleen and induce extramedullary hematopoiesis (EMH). While the bone marrow HSC niche has been studied intensively, the EMH niche has received little attention. Here, we systematically assessed the physiological sources of the key niche factors, SCF and CXCL12, in the mouse spleen after EMH induction by cyclophosphamide plus granulocyte colony-stimulating factor, blood loss, or pregnancy. 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) The HSC niche factor SCF is required for HSC maintenance. Using an Scf-GFP knockin mouse, we have identified a perivascular cell type in the bone marrow expressing high level of Scf. To characterize the novel Scf-GFP+ cells from the bone marrow, we performed microarray analysis on these cells.

(Submitter supplied) The study is designed to identify transcriptional differences of CD45-Ter119-Cxcl12-DsRed+ stromal cells at different develomental stages. 50,000 CD45-Ter119-Cxcl12-DsRed+ stromal cells from freshly prepared livers of E15.5, P5 and P10 Cxcl12DsRed/+ mice were sorted into Trizol by flow cytometry. Total RNA was isolated and amplified with the WT-Ovation Pico RNA Amplification system (Nugen) as the manufacturer’s instructions. 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) Fate decisions of haematopoietic stem cells (HSCs) to self-renew or differentiate in response to various demands are finely tuned by specialized microenvironments called “niches” in the bone marrow. Recent studies suggest that arterioles and sinusoids accompanied with distinct stromal cells marked by nerve/glial antigen 2 (NG2) and leptin receptor (LepR), compose distinct niches regulating quiescence and proliferation of HSCs, respectively. more...

(Submitter supplied) Hematopoietic stem and progenitors cells interact with organ specific stem cell niches.

(Submitter supplied) Extramedullary hematopoiesis (EMH) refers to the differentiation of hematopoietic stem cells (HSCs) into effector cells that occurs in compartments outside of the bone marrow. Previous studies linked pattern recognition receptor (PRR)-expressing HSCs, EMH and immune responses to microbial stimuli. However, the factors that regulate EMH and whether EMH operates in broader immune contexts remain unknown. more...

(Submitter supplied) Although endothelial cells (ECs) have been shown to contribute to HSC maintenance in bone marrow (BM), differential contributions of EC subtypes remain unknown, owing to the lack of methods to separate with high purity arterial (AEC) from sinusoidal (SEC) endothelial cells. We show that combination of podoplanin (PDPN) and Sca-1 expression distinguishes AEC from SEC where Sca1brightPDPN—CD45—Ter119— cells exhibit an arterial gene signature and PDPN+Sca1dimCD45—Ter119— marks sinusoids. more...

(Submitter supplied) Bone marrow mesenchymal stromal cells (MSCs) that express high levels of stem cell factor (SCF) and CXC chemokine ligand 12 (CXCL12) are one crucial component of the hematopoietic stem cell (HSC) niche. While the secreted factors produced by MSCs to support HSCs have been well described, little is known regarding the transcriptional regulators controlling the cell fate of MSCs and thus indirectly maintaining HSCs. more...

(Submitter supplied) In the bone marrow, CXCL12 and IL7 are essential for B cell differentiation whereas hematopoietic stem cells (HSC) maintenance requires SCF and CXCL12. Previous studies, including ours, indicate that peri-sinusoidal stromal (PSS) cells are heterogeneous and that part of them express and are the main source of IL7. Our single cell qPCR and transcriptomic analysis demonstrate that SCF, CXCL12 and IL7 are co-expressed by a unique peri-sinusoidal stromal cell subset.

(Submitter supplied) Hematopoiesis in adult mammals involves cognate interactions between developing hematopoietic cells and bone marrow stromal cell niches. SCF and CXCL12 play key roles in the maintenance of HSC, while early B cell differentiation requires CXCL12 and IL7. In this study, we characterized mouse BM stromal cells expressing IL7 by performing a transcriptomic analysis. We found that SCF, CXCL12 and IL7 were co-expressed by a unique peri-sinusoidal stromal cell subset.
