Mast cells in rheumatoid synovial tissue with electron microscopy

The aim of this study was to search for the presence of mast cells in the synovial tissues of rheumatoid arthritis [RA] with electron microscopy in a trial to understand the pathogenesis of the disease. Synovial tissues were obtained from 10 RA patients. The presence of mast cells was examined with electron microscopy. The presence of mast cells was not demonstrated in the synovial tissues of RA with electron microscopy. Electron microscopy is not a suitable method for demonstrating the presence of mast cells in the synovial tissue of RA patients
