A549 cell spheres were treated with DDP, BSO combined with DDP, and NAC combined with DDP. (a) The ROS levels of A549 cell spheres exposed to different treatments were detected by an ROS Assay kit, and the concentration was determined by flow cytometry among the C, D, B+D, and N+D groups. (b) ROS levels in A549 sphere cells among different treatments. Data are presented as the of three independent experiments. vs. the control group; # vs. the D group; & vs. the B+D group. DDP: cisplatin; BSO: DL-buthionine-(S,R)-sulphoximine; NAC: N-acetylcysteine; ROS: reactive oxygen species.
