Project description:Interaction of bone marrow stroma and monocytes: bone marrow stromal cell lines cultured with monocytes
| PRJNA107753 | ENA
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:The natural history of multiple myeloma is characterized by its localization to the bone marrow and its interaction with bone marrow stromal cells. The bone marrow stromal cells provide growth and survival signals, thereby promoting the development of drug resistance. Here, we show that the interaction between bone marrow stromal cells and myeloma cells (using human cell lines) induces chromatin remodeling of cis-regulatory elements and is associated with changes in the expression of genes involved in the cell migration and cytokine signaling. The expression of genes involved in these stromal interactions are observed in extramedullary disease in patients with myeloma and provides the rationale for survival of myeloma cells outside of the bone marrow microenvironment. Expression of these stromal interaction genes is also observed in a subset of patients with newly diagnosed myeloma and are akin to the transcriptional program of extramedullary disease. The presence of such adverse stromal interactions in newly diagnosed myeloma is associated with accelerated disease dissemination, predicts the early development of therapeutic resistance, and is of independent prognostic significance. These stromal cell induced transcriptomic and epigenomic changes both predict long-term outcomes and identify therapeutic targets in the tumor microenvironment for the development of novel therapeutic approaches.

Project description:Two human stromal cell lines, HS-5 and HS-27a, represent functionally distinct components of the bone marrow microenvironment. A third influential component of the microenvironment is resident monocytes and macrophages. The baseline expression profile of normal peripheral blood monocytes was determined and their effect on the gene expression of the stromal cells was investigated in a co-culture sytem. Control RNA for all samples was Stratagene Universal human reference RNA. Keywords: Cell Line Comparison and Culture Comparison

Project description:Evidence suggests that the bone marrow microenvironment (niches) support hematopoietic stem cells (HSCs). The cell-cell interaction between bone marrow mesenchymal stromal cells (BMSCs) and HSCs plays a crucial role in hematopoiesis. The aging of BMSCs lead to decreased ability to maintain hematopoiesis. We used microarray to determine the age-related change of BMSCs.

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 (MSC) as well as monocytes and resident macrophages, which are derived from the hematopoietic stem cells. Clinical studies have shown healing effects, direct or indirect, from the injection of MSC int Keywords: Cell type comparison Canine bone marrow stromal cells were immortalized by transduction with a replication-defective recombinant retrovirus containing the human papilloma virus E6/E7 genes (pLXSN-16 E6E7), as described for human stromal cell lines in Roecklein and Torok-Storb (Blood 85:997-1005, 1995). Transduced clones were selected with 50 ug/ml G418 and resistant clones were isolated, grown to confluency and characterized for morphology, cytokine production and cell surface molecule expression. These cells are intended for clinical research in the canine transplantation model, as a complement for existing human stromal cell lines, for mitigation of graft-versus-host disease and radiation effects.

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: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.
