Analysis of andrographolide effects on cell viability of NK and NSCLC cells. Expanded NK cells and NSCLC cells were treated with different concentrations of andrographolide (Andro) for 24, 48 and 72 h, respectively. Panel a, represents NK cell viability as determined by CCK8 assay. Panel b, represents NSCLC cell viability as assessed by MTT assay. Three independent experiments were performed. Data are expressed as means ± S.E.M. *, P<0.05; **, P<0.01; ***, P<0.001
