Figure 4: Inhibition of VEGF production of D1 cells by dexamethasone is dose and time dependent. VEGF expression in supernatant medium of the D1 cells treated with (a) different concentrations of dexamethasone for 24 h and (b) 10−7 mol/L dexamethasone for different time points was assessed by ELISA. Each column shows mean ± SD of data from three experiments ( ). (Reprinted, with permission, from: [56].)
