Fig. 4From: Comparison of mesenchymal stem cells obtained by suspended culture of synovium from patients with rheumatoid arthritis and osteoarthritisDifferentiation assays of the cells passaged after suspended culture of synovium from patients with rheumatoid arthritis (RA; n = 8) and osteoarthritis (OA; n = 6). a Chondrogenesis. Representative macro pictures and histological sections stained with safranin O are shown. b Cartilage pellet weight. Average values with standard deviation are shown. NS: not significant. c Calcification. Representative cell colonies stained with alizarin red are shown. d Adipogenesis. Representative cell colonies stained with oil red O are shownBack to article page
