Figure 5. Effect of resveratrol against cell death induced by SNP in HaCaT cells.

Cells were exposed to SNP (0.3–3 mM) in the presence or absence of resveratrol (1–30 µM). Cell viability was determined 24 hours later using both the MTT and calcein AM assays. Values represent mean ± SEM of at least three separate experiments. *p<0.05, **p<0.01 comp.
