3-dimethylthiazol-2,5-diphenyltetrazolium bromide (MTT) viability test: histograms of Saos-2 (A) and periosteal derived precursor cells (PDPCs) (B) cultured with different concentrations of arbutin for up to 72 h. Histograms of Saos-2 (C) and PDPCs (D) cultured with 0.2 mM of arbutin and exposed to oxidative stress (48 h = 24 h after stress induction, 72 h = 48 h after stress induction). Data are expressed as the percentage of Saos-2 or PDPCs cultured without arbutin after 24 h (control); * p < 0.05 vs. ctrl.
