Evaluation of CD98 Expression in Normal and Osteoarthritic Human Articular Chondrocytes
Background: Recent studies have provided evidence that integrins play roles in recognition of mechanical stimuli and its translation into a cellular response. Integrin signaling may be regulated by a number of mechanisms including accessory proteins such as CD98 (4F2 antigen). Objectives: To determine CD98 expression by human articular chondrocytes and its involvement in human articular mechano...
متن کاملDifferential Immunohistochemical Expression Pattern of Galectin-3 in Normal and Osteoarthritic Human Articular Cartilage
Background: Previous studies have shown that Galectin-3, a member of lectin family, is expressed in developing cartilage in mouse embryo and also in growth plate of long bones. Objective: In the present work, the expression pattern of Galectin-3 in normal and various grades of osteoarthritic (OA) human articular cartilage has been studied. Methods: Using immunohistochemistry and standard we...
متن کاملThe Expression of Signal Regulatory Protein-alpha in Normal and Osteoarthritic Human Articular Cartilage and Its Involvement in Chondrocyte Mechano-transduction Response
Signal regulatory proteins (SIRP) belong to immunoglobulin super family (IgSF) and relate to integrin signaling cascades. It has been shown that SIRPa is expressed in a variety of cells including myeloid cells and neurons. In the present study the expression of this IgSF member in articular chondrocytes was investigated. Methods: Using a panel of anti-SIRPalpha antibodies, immunohistochemistry...
متن کاملCD147 (Extracellular Matrix Metalloproteinase Inducer-EMMPRIN) Expression by Human Articular Chondrocytes
Background: Integrins are a family of transmembrane proteins that allow communication between the extracellular matrix and the interior of cells. Chondrocytes, cells of articular cartilage, express integrins and these molecules appear to have a variety of roles including mechanotransduction. Integrins are known to associate with a number of accessory molecules such as CD147 that may act to regu...
متن کاملChondrocyte number and proteoglycan synthesis in the aging and osteoarthritic human articular cartilage.
OBJECTIVE To correlate the number of chondrocytes in healthy and osteoarthritic human articular cartilage with age, and to evaluate the influence of donor age on total proteoglycan synthesis. METHODS Chondrocytes were isolated from human articular cartilage derived from hip joints with and without osteoarthritic lesions. The cell number was normalised to cartilage sample wet weight. In additi...
