MSCs were incubated with increasing concentrations of piceatannol, and cytotoxicity was evaluated after 48 h with the CCK-8 assay (Dojindo Molecular Technologies, Kumamoto, Japan). Data are expressed in arbitrary units and shown with standard deviation (SD), n = 3. The *** p < 0.001 and * p < 0.05 indicates statistical significance between the control and treated samples.
