Effect of sodium nitroprusside (SNP) on the cell viability of human osteoarthritic (OA) synoviocytes. Human OA synoviocytes were incubated under basal conditions (RPMI only) or with SNP at concentrations of 0.5, 1 and 2 mM for 24, 48 and 72 hours. Cell viability was evaluated using a colorimetric analysis based on the MTT assay as detailed in the Methods section. The data are expressed as percentages of those of the control conditions (100%), and represent the mean ± standard error of eight different experiments performed in duplicate (*p < 0.05).
