Project description:Bone marrow microenvironment: interaction of monocytes and stromal cells
| PRJNA93419 | ENA
Project description:The hematopoietic microenvironment consists of non-hematopoietic derived stromal elements and hematopoietic derived monocytes and macrophages which interact and function together to control the proliferation and differentiation of early blood-forming cells. Two human stromal cell lines (HS-5 and HS-27a) representing distinct functional components of this microenvironment have been extensively characterized and shown to influence monocyte gene expression. This series of gene expression profiles is intended to extend the previous studies and identify which gene expression changes may require cell-cell contact or occur in the stromal cells as a result of monocyte influence;or in the monocytes as a result of stormal influences. Experiment Overall Design: Two human bone marrow stromal cell lines (HS5 and HS27a) were cultured with and without monocytes (CD14+ cells) from 2 different donors. Experiment Overall Design: culture condition: stroma no monocytes: HS5-1, HS5-2, HS27a-1, HS27a-2 Experiment Overall Design: culture condition: stroma with monocytes: HS5-MO-1, HS5-MO-2, HS27a-MO-1, HS27a-MO-2 Experiment Overall Design: donor: donor 3: HS5-MO-1, HS27a-MO-1 Experiment Overall Design: donor: donor 4: HS5-MO-2, HS27a-MO-2 Experiment Overall Design: cell line: HS5: HS5-1, HS5-2, HS5-MO-1, HS5-MO-2 Experiment Overall Design: cell line: HS27a: HS27a-1, HS27a-2, HS27a-MO-1, HS27a-MO-2

Project description:The bone marrow microenvironment is a complex mixture of cells that function in concert to regulate hematopoiesis. Cellular components include fixed nonhematopoietic stromal elements as well as monocytes and resident macrophages, which are derived from the hematopoietic stem cells. Although these monocyte-lineage cells are reported to modify stromal cell function, the reverse also occurs. Given the secretory capability of the monocyte/macrophage and their various potential functions, it is not surprising that stromal cells contained within a particular niche can modify monocyte gene expression and functional maturation. Experiment Overall Design: Monocytes were isolated from peripheral blood mononuclear cells from 2 different normal donors and cultured for 48h in conditioned medium (CM). The CM was collected from each of two functionally distinct human bone marrow stromal cell lines (HS5 and HS27a) representing different compartments of the bone marrow microenvironment (Roecklein BA, Torok-Storb B. Blood. 1995;85:997-1005). Four samples were analyzed, with two biological replicates for each CM.

Project description:Our study aims to examine the interaction between AML cells and other cells in the tumor microenvironment, specifically bone marrow derived mesenchymal stromal cells. To delineate the specific genes/pathways involved in this interaction, we have co-cultured AML cell lines alone or with bone marrow derived mesenchymal stromal cells for 3 days, extracted total RNA from AML cells and analyzed the samples by RNA-seq. We identified the genes that are differentially expressed in co-cultured AML cells compared to AML cells alone. We found that TGF-β1 associated gene signature is activated in AML cells in the presence of BM-MSCs compared to AML cells alone.

Project description:Intercellular communication within the bone marrow niche significantly influences leukemogenesis and the sensitivity of leukemic cells to therapy. However, the landscape of possible cell-cell interactions is still incomplete. Tunneling nanotubes (TNTs) are a novel mode of intercellular cross-talk. They are long, thin membranous conduits that enable the direct transfer of various cargo between cells. The present study found that TNTs are formed between leukemic and bone marrow stromal cells. Confocal three-dimensional reconstructions, correlative light-electron microscopy, and electron tomography provided evidence that TNTs transfer cellular vesicles between cells. The quantitative analysis demonstrated the stimulation of TNT-mediated vesicle transfer from stromal cells to leukemic cells by the stromal component. The vesicular cargo that was received from stroma cells conferred resistance to anti-leukemic treatment. Moreover, specific sets of proteins with a potential role in survival and the drug response were transferred within these vesicles. Altogether, we found that TNTs are involved in a novel and potent mechanism that participates in leukemia-stroma cross-talk and the stroma-mediated cytoprotection of leukemic cells. Our findings implicate TNT connections as a possible target for therapeutic interventions within the leukemia microenvironment to attenuate stroma-conferred protection.
