Gene expression profiling of mouse bone marrow-derived macrophages (RNA-Seq)

Project description:Bone marrow (BM) cells were obtained by flushing the long bones of 8-week old C57BL/6 mice. BM cells were then were plated in macrophage SFM medium (Life Technologies) supplemented with penicillin-streptomycin and CSF-1 (Peprotech, 100 ng/ml) and cultured for one week to allow macrophage differentiation. BMDMs were polarized by adding IL-4 to the medium (40 ng/ml, Peprotech) for 72h or left untreated.

Multiple myeloma-derived extracellular vesicles modulate the bone marrow immune microenvironment

Project description:One of the hallmarks of multiple myeloma (MM) is a permissive BM microenvironment. Increasing evidence suggest that cell-to-cell communication between myeloma and immune cells via tumor cell-derived extracellular vesicles (EV) plays a key role in the pathogenesis of MM. Hence, we aimed to explore BM immune alterations induced by MM-derived EV. For this, we inoculated immunocompetent BALB/cByJ mice with a myeloma cell line - MOPC315.BM -, inducing a MM phenotype. Upon tumor establishment, characterization of the BM microenvironment revealed the expression of both activation and suppressive markers by lymphocytes, such as Granzyme b and PD-1, respectively. In addition, conditioning of the animals with MOPC315.BM-derived EV, before transplantation of the MOPC315.BM tumor cells, did not anticipate the disease phenotype. However, it induced features of suppression in the BM milieu, such as an increase in PD-1 expression by CD4+ T cells. Overall, our findings reveal the involvement of MOPC315.BM-derived EV protein content as promoters of immune niche remodeling, strengthening the importance of assessing the mechanisms by which MM may impact the immune microenvironment.

Gene expression profiling of mobilized vs. Bone marrow (BM) resident hematopoietic stem and progenitor cells (LSK)

Project description:Expression prolile of CWHM-823+tGro-b mobilized (3 mg/kg + 2.5 mg/kg, s.c. injection, timepoint 30 min) HSPC was compared to that of AMD3100 (5 mg/kg, 1 hr after s.c. injection) or G-CSF (100 ug/kg/injection, q12h, 5 days) mobilized as well as BM resident HSPC. Accordingly, the cells were isolated from the BM of untreated or from the peripheral blood (PB) of differentially mobilized mice.

Global miRNA Expression of Bone Marrow Mesenchymal Stem/Stromal Cells in Fanconi Anemia Patients Before and After Bone Marrow Transplantation, and their Allogeneic Bone Marrow Donors

Project description:Fanconi anemia (FA) is a rare genetic disorder characterized by genomic instability, developmental defects and bone marrow failure. Homeostasis of hematopoietic stem cells (HSCs) in the bone marrow partly relies on their direct or indirect interactions with the mesenchymal stem/stromal cells (MSCs). miRNAs can play a critical role during these interactions. There is no study available so far addressing the miRNA profile of bone marrow (BM-) MSCs in FA disease state. Non-coding RNA expression profiling was performed in BM-MSCs obtained from Donors (siblings of FA patients) as well as FA patients before (preBMT) and after bone marrow transplant (postBMT) using GeneChip miRNA 2.0 Array. Quality Control (QC) was performed via Normalized Unscaled Standard Errors (NUSE) and Relative Log Expression (RLE) before further analysis.

Human bone marrow comprise atypical adipocytes with specific lipid metabolism

Project description:Under caloric restriction, bone marrow adipocytes (BM-Ad) do not decrease in size conversely to white adipocytes, suggesting their unique metabolic properties. We compared human primary BM-Ad with paired subcutaneous adipocytes (SC-Ad) using proteomic and lipidomic approaches. We found that while SC-Ad and BM-Ad share similar morphological features, they possess distinct lipid metabolism. BM-Ad shows enrichment in proteins involved in cholesterol metabolism correlating with increased free cholesterol content while proteins involved in lipolysis were downregulated. In particular, monoacylglycerol lipase expression was strongly reduced in BM-Ad, leading to accumulation of monoacylglycerol. Consequently, basal and induced lipolytic responses were absent in BM-Ad, affirming their differences in metabolic fitness upon caloric restriction. These specific metabolic features are not recapitulated in vitro using common protocols to differentiate bone marrow mesenchymal stem cells. Thus, contrary to classical SC-Ad, BM-Ad display a specific lipid metabolism, as they are devoid of lipolytic activity and exhibit a cholesterol-orientated metabolism.

Comparison of C57Bl/KalwRij mouse bone marrow to C57BL6 mouse bone marrow

Project description:Multiple myeloma is a fatal hematological malignancy. In order to develop effective therapeutic approaches, it is critical to understand the pathogenesis of myeloma. The Radl 5T model of multiple myeloma is a clinically relevant murine model where myeloma spontaneously occurs in aged, in-bred C57BlKalwRij mice and can be propagated by intravenous inoculation of 5T myeloma cells into mice of the same strain. Importantly inoculation of 5T myeloma cells into C57Bl6 mice does not result in myeloma, demonstrating that the bone marrow (BM) microenvironment of the C57BlKalwRij strain provides a unique and permissive milieu for myeloma development. We hypothesized that cells of the BM microenvironment may provide essential stimuli for the development of multiple myeloma in vivo. We aim to determine the differences in expression within the bone marrow of C57Bl/KalwRij mice.

Efficacy of JAK 1/2 inhibition in murine immune bone marrow failure

Project description:Background and methods: Ruxolitinib (RUX) is a Jak inhibitor that is used in the treatment of intermediate or high risk myelofibrosis and resistant forms of polycythemia vera and graft-vs-host disease due to its efficacy of reducing inflammatory cytokines and markers of inflammation. We tested its potential therapeutic effects in murine models of immune-mediated bone marrow failure. RNA-Seq and analysis was performed using NEBNext Ultra™ II RNA Library Prep Kit for Illumina and Illumina Novaseq6000, according to the Institute's protocols. Results: As both prophylaxis and therapy, Ruxolitinib improved pancytopenia and BM cellularity and decreased BM T cell infiltration in bone marrow failure mice. RNA sequencing demonstrated that Ruxolitinib suppressed expression of inflammtory genes in bone marrow infiltrated CD8 T cells compared with untreated mice. Conclusion: Our results demonstrate that Ruxolitinib is highly effective in attenuation of disease and extending survival of immune-mediated bone marrow failure mice.
