Figure 4: Effects of dexamethasone on inducible nitric oxide synthase gene expression of osteoblasts and osteoclasts. The expression of inducible nitric oxide synthase after dexamethasone treatment in osteoblasts (a) and osteoclasts (b). Each column represents the mean ± standard error of the mean of at least three independent experiments. *Significant difference between treatments where P < 0.05
