Terpinen-4-ol Induces Apoptosis in Human Nonsmall Cell Lung Cancer In Vitro and In Vivo

Figure 1

Effects of terpinen-4-ol on viability and morphology of A549 and CL1-0 cells. (a) A549 and CL1-0 cells were seeded at 5 × 104 cells/well and then treated with the indicated concentrations of terpinen-4-ol for 24 hours following attachment. The cell viability was determined by the MTT assay. Each point on the graph represents the mean ± SD of triplicate tests. value <.05 compared with the untreated control group. (b) The morphology of A549 and CL1-0 cells treated with various concentrations of terpinen-4-ol for 24 hours were observed by phase-contrast microscopy and photographed (400×).
