Relative gene expression normalized to GAPDH and day 0 (2−∆∆Ct) of human articular chondrocytes after 7 days of culture in passage 2, 3, and 4 on hydrogel, on polystyrene or in pellet culture. (A) ACAN expression in OA chondrocytes; (B) ACAN expression in non-OA chondrocytes; (C) SOX9 expression in OA chondrocytes; (D) SOX9 expression in non-OA chondrocytes; (E) MMP13 expression in OA chondrocytes; (F) MMP13 expression in non-OA chondrocytes (non-OA pellet passage 2 compared to non-OA pellet passage 4: p = 0.0002).
