Osteoarthritic synovial tissue inhibition of proteoglycan production in human osteoarthritic knee cartilage: Establishment and characterization of a long-term cartilage-synovium coculture

Abstract

OA synovium affects cartilage metabolism by reducting GAG production. Triamcinolone can relieve this effect of synovial tissue, while being inhibitory when added to cartilage monoculture. These results clearly indicate the importance of tissue coculture as a promising tool for studying OA pathophysiology and for development of possible interventions.
