(Submitter supplied) Multipotent stromal cells (MSC) and their osteoblastic lineage cell (OBC) derivatives are part of the bone marrow (BM) niche and contribute to hematopoietic stem cell (HSC) maintenance. During myeloproliferative neoplasm (MPN) development, MSCs are stimulated to overproduce functtionally altered OBCs, which accumulate in the BM cavity as myelofibrotic cells. These MPN-expanded OBCs, in turn, impair the maintenance of normal HSCs but not of leukemic stem cells. more...

Analysis of osteoblastic lineage cells (OBC) from Scl-tTA::TRE-BCR/ABL (BA) double-transgenics withdrawn from doxycycline at 5 weeks of age to induce myeloproliferative neoplasia (MPN). MPN development drives OBC expansion. Results provide insight into molecular features of MPN-expanded OBCs.

(Submitter supplied) Myeloproliferative neoplasms (MPNs) are diseases caused by mutations in the haematopoietic stem cell (HSC) compartment. Most MPN patients have a common acquired mutation of Janus kinase 2 (JAK2) gene in HSCs that renders this kinase constitutively active, leading to uncontrolled cell expansion. The bone marrow (BM) microenvironment might contribute to the clinical outcomes of this common event. We previously showed that BM nestin+ mesenchymal stem cells (MSCs) innervated by sympathetic nerve fibres regulate normal HSCs. more...

(Submitter supplied) Transcriptional profiling of mouse mesenchymal stem/progenitor cells (MSPC) comparing control Ptpn11+/+ MSPC with Ptpn11E76K/+ MSPC. By obtaining 20 million reads of sequence from two pair, we confirmed our cytokine/chemokine array data and quantitative ELISA data from both mouse and patient-derived specimens. CCL3, CCL12, CCL4, and CXCL12 (SDF-1) were aberrantly produced by Ptpn11 mutated MSPCs

(Submitter supplied) Hematopoietic stem cell (HSC) function requires bone marrow vascular niches, which have been proposed to be co-opted by leukemia cells to support their propagation. Acute myeloid leukemia (AML) cells produce angiogenic factors; however, anti-angiogenic therapies have not improved AML patient outcome. Using intravital microscopy we uncovered hierarchical vascular remodeling with AML progression. AML cells outcompete non-malignant hematopoiesis by gradual elimination of stroma cells, endosteal endothelium, and osteoblastic cells. more...

(Submitter supplied) Mesenchymal stromal cells are a critical component of the bone marrow hematopoietic stem cell niche. In myelofibrosis, these cells are the major source of fibrosis in the bone marrow. We performed gene expression analysis using microarrays to systematically elucidate the mechanisms leading to fibrogenic conversion of these cells.

(Submitter supplied) The bone marrow (BM) niche regulates multiple HSC processes. Clinical treatment for hematological malignancies, by HSC transplantation often requires preconditioning total body irradiation, which severely and irreversibly impairs the BM niche and HSC regeneration. Novel strategies to enhance HSC regeneration in irradiated BM are needed. We compared the effects of niche factors EGF, FGF2 and PDGFB on HSC hematopoietic regeneration using human MSCs that were transduced with these factors via lentiviral vectors. more...
