Open Access Abstract Vascular endothelial growth factor VEGF promotes cartilagedegrading pathways and there is evidence for the involvement of reactive oxygen species ROS in cartilage degeneration. However a relationship between ROS and VEGF has not been reported. Here we investigate whether the expression of VEGF is modulated by ROS. Aspirates of synovial fluid from patients with osteoarthritis OA were examined for intra-articular VEGF using ELISA. Immortalized C28 I2 chondrocytes and human knee cartilage explants were exposed to phorbol myristate acetate PMA 020 pg ml .
