Cellular cytotoxicity of resveratrol and pterostilbene in PBECs. PBECs were incubated in absence (non-treated, NT) or presence of 150 µM resveratrol and 60 µM pterostilbene at basolateral side for 48 h. Cell viability was assessed by flow cytometry using (A) life/death staining and (B) a LDH assay. (C) Gating strategy flow cytometry. Cell population was gated with gate D; doublets were excluded with gate E; live population was determined with gate F. Data represents mean ± SEM, symbols represent two independent donors.
