Fig. 3From: Calotropis gigantea extract induces apoptosis through extrinsic/intrinsic pathways and reactive oxygen species generation in A549 and NCI-H1299 non-small cell lung cancer cellsEffects of CG on viability and apoptosis in A549 and NCI-H1299 cells. Microscopic images of A549 (a) and NCI-H1299 (b) cells treated with CG for 48 h. After treatment with the indicated concentrations of CG for 48 h, A549 (c) and NCI-H1299 (d) cells were stained with Annexin V-FITC/PI. The untreated cells were compared with CG-treated cellsBack to article page
