Cell colonies and harvested cell numbers after suspended culture of synovium from patients with rheumatoid arthritis (RA; n = 8) and osteoarthritis (OA; n = 6). a Representative cell colonies stained with crystal violet after 7 days of suspended synovium culture. b Passage 0 cell numbers/g synovium after 14 days of suspended synovium culture. c Passage 1 cell numbers/g synovium after14 days of culture of passage 0 cells. Average values with standard deviation are shown (RA, n = 8; OA, n = 6). NS: not significant
