Growth inhibition effect of K562 cells induced by resveratrol. A. The chemical structure of resveratrol. B. K562 cells were exposed to increasing concentrations of resveratrol or an equal volume of the drug’s vehicle DMSO for up to 72 h. Viable cells were evaluated by MTT assay and denoted as a percentage of untreated controls at the concurrent time point. The bars indicate mean ± S.D. (n=3).
