Fig. (1) Chondrocyte damage after exposure to IC. Chondrocytes were treated with IC and were analyzed by light microscopy. (A) Untreated control chondrocytes. (B) Chondrocytes treated with Triton X100, a known inducer of cell necrosis. (C) Chondrocytes treated with 1% IC. (D) Chondrocytes incubated with 10% IC. (E) Chondrocytes treated with 100% IC. One representative result is shown from at least three independently performed experiments.
