Figure 2 .

Influence of clodronate, pamidronate, and risedronate on chondrocytes co-incubated with dexamethasone 10^-7 mol/l (closed symbols) or 10^-5 mol/l (open symbols). Results expressed as percentage of inhibition of: (A) necrosis; (B) growth retardation; (C) apoptosis measured by annexin V; and (D) apoptosis measured by TUNEL. Bars represent the standard error of the mean of three experiments. *p<0.05: chondrocytes incubated with both dexamethasone and bisphosphonates v chondrocytes incubated with dexamethasone alone.
