Project description:To determine whether extracellular vesicles were also present in human disease, we isolated and evaluated extracellular vesicles from synovial fluid from normal and OA patients at relatively advanced ages (70 - 80 years). Here we report the altered expression of synovial fluid extracellular vesicles-derived miRNAs in osteoarthritis compared to normal patients with age-relate degeneration to investigate potential biomarkers for OA diagnosis. The OA donors had clinical evidence of OA based on pain that led to total joint arthroplasty.
Project description:Analysis of neutrophil proteomic alterations induced by migration towards inflamed joints in juvenile idiopathic arthritis (JIA). In this experiment neutrophil proteomes were investigated after migration towards JIA synovial fluid in an in vitro model of a synovial membrane, compared to neutrophils incubated in synovial fluid without migration. The migration model consisted of transwell inserts with human knee synoviocytes on the undersides and HMEC endothelial cells on the insides, placed in wells containing medium with 10 % JIA synovial fluid.
Project description:To explore mRNA expression profiling in synovial fluid derived stem cells (SFSCs), gene expression analysis was performed on 3 SFSCs and 1 BMMSC.
Project description:Small RNA isolated from synovial fluid of the metacarpophalangeal joints of horses. Horses either had minimal signs of osteoarthritis based on macroscopic and microscopic joint scoring or early (mild) osteoarthritis. Differential expression of small non-coding RNAs was undertaken.
Project description:In the current work, we used an isotopically labeled high resolution LC MS/MS-based proteomics approach to analyze the protein profile of synovial fluid at 6 and 12 months after ACL transection in untreated and repaired porcine knees. Our primary aim was to determine how the synovial fluid proteome differs between the two groups in an effort to identify candidate proteins that may be associated with the development of posttraumatic OA. We hypothesized that the development of macroscopic cartilage damage following surgical ACL transection would be accompanied by differential changes in synovial fluid proteome in untreated knees compared to repaired joints.
Project description:Single-cell transcriptome of >55,000 cells multiplexed into 4 channels obtained from peripheral blood and synovial fluid of two patients with HLA-B27+ ankylosing spondylitis,.
