Project description:We cultured bone marrow derived dendritic cells from WT and CD11c KO mice. Then, a group of bone marrow dendritic cells were stimulated with LPS overnight. We obtained bone marrow derived dendritic cells with or without LPS stimulation and analyzed proteomics profiles.
Project description:To investigate the transcriptome level changes in human bone marrow-derived mesenchymal stem cells following treatment with TGF-b2, we used RNA-sequencing to compare gene expression between cells from the same donors cultured in standard media or media containing 1 ng/ml TGF-b2.
Project description:We use tolDCs from syngeneic (C57BL6) and allogeneic (BALB/c) mice to show potent renoprotective abilities in a ischemia reperfusion AKI model. Dendritic cells were derived from mice bone marrow and cultured for 7 days with GM-CSF and IL-4. Tolerogenic DCs were cultured in the same DC media but with the addition of VitD3 and IL10. LPS was added on day 6 and cells harvested for use or analysis on day 7.
Project description:investigate the proximal proteins on the porositophorous vacuole membranes when toxoplasma gondii ME49 infected mouse bone marrow derived dendritic cells were primed under different conditions. The priming condition using IFN gamma will induce the formation of GBP+ puncta on a portion of PVM. The constituents of the GBP+ puncta are also investigated.
Project description:Various culture media that can rapidly expand bone marrow stromal cells (BMSCs) are currently available. However, the effects of those culture media on the contents of extracellular vesicles released by bone marrow stromal cells have not been fully understood. Using BMSCs from 6 healthy donors were cultured in two different culture media and characterized the small RNA profiles in extracellular vesicles.
Project description:Fibroblasts usually mediate acute wound healing and long-term tissue remodeling with scarring in tissue injury. In myocardial infarction (MI), following a prolonged lack of oxygen supply, necrotized cardiomyocytes become replaced by secreted extracellular matrix proteins produced by fibroblasts. Dendritic cells (DCs) act as inflammatory cells and can migrate from the bone marrow to the infarct areas and infarct border areas to mediate collagen accumulation after MI, whereas trichostatin A (TSA) can regulate the apoptosis and proliferation of the fibroblasts and affect DCs functions under oxygen–glucose deprivation (OGD) conditions. In this study, we used proteomics to investigate the effects of TSA and bone marrow-derived dendritic cells (BMDCs) on NIH3T3 fibroblasts under OGD conditions. Results showed that the fatty acid degradation pathway was significantly upregulated in NIH3T3 cells under OGD conditions, and the fatty acid synthesis pathway was significantly downregulated in NIH3T3 cells treated with BMDCs conditioned media with TSA (BMDCs-CM[TSA]) under OGD conditions. Meanwhile, the BMDCs-CM(TSA) significantly decreased the levels of triglycerides and free fatty acids and mediated ten fatty acid metabolism-related proteins in the NIH3T3 cells under OGD conditions. Summarily, the proteomic analysis showed that TSA and BMDCs affect fatty acid metabolism in NIH3T3 cells under OGD conditions.
Project description:Gene expression in primary erythroid cells and in bone marrow stromal cells following treatment with Sotatercept (ACE-011) Gene expression profiles of erythroid cells derived from human CD34+ cells generated under standard conditions and in cultures containing conditioned media from bone marrow stromal cells treated in vitro with ACE-011; Gene expression profiles of untreated bone marrow stromal cells and of stromal cells treated with ACE-011.
Project description:Granulocyte-Macrophage colony stimulating factor (GM-CSF) devlops heterogenous myeloid cell populations from bone marrow progenitor cells. In vitro generated bone marrow derived cells are excellent sources for obtaining dendritic cells or macrophages, but it is still not clear about the exact mixed population characteristics of GM-CSF grown cells. We revealed here that GM-CSF grown bone marrow cell derived attaching cells were composed of dendritic cells (GM-BMDC) as well as macrophages (GM-BMM). We compared the transcriptome profiles of these cell populations as well as M-CSF grown bone marrow derived macrophages (M-BMM). We used microarrays to detail the global profile of gene expressions between three populations of CSF-grown bone marrow derived cells: GM-CSF derived dendritic cells (GM-BMDC), GM-CSF derived macrophages (GM-BMM) and M-CSF derived macrophages (M-BMM). Bone marrow cells were differentiated for 7 days with 25 ng/ml GM-CSF or 20% L cell conditioned media as a M-CSF supplier. GM-BMDCs were sorted from MHCIIhighF4/80low population and GM-BMMs were sorted in the MHCIIlowF4/80high population. M-BMMs were sorted from CD11b+F4/80+ population.
Project description:Bone marrow derived dendritic cells were cultured and stimulated with I-BET151 or DMSO control, and stimulated with Ovalbumin-IgG immune complex or Ovalbumin control.
