摘要: Synovium and cartilage from patients with osteoarthritis or rheumatoid arthritis were analyzed for expression of oligomeric matrix protein. Immunostaining synovium antiserum to protein demonstrated positive staining in both diseases. In osteoarthritis, there was within the synovial cells immediately subjacent connective tissue, less intense deeper tissue. arthritis, marked situ hybridization performed an antisense digoxigenin-labeled riboprobe human confirmed presence mRNA lining types synovium. Quantitative polymerase chain reaction a MIMIC increased as compared osteoarthritic synovium, respectively; levels similar those chondrocytes. As result high inflammatory should be considered potential tissue source any investigation biological markers metabolism. The upregulated tissues suggests its vivo regulation by cytokines.
