Evaluation of degradative factors expressed by passage 1 (p.1) and passage 5 (p.5) synovial cells from osteoarthritic moderate-grade synovitis. ADAMTS4, ADAMTS5, MMP13, S100A8, and S100A9 were evaluated in the supernatant of both p.1 and p.5 synovial cells as described in “Methods”. Data are expressed as the median and interquartile range (n = 22). *Significant differences between p.1 and p.5 synovial cells: p < 0.005. ND not detected
