Cold Atmospheric Plasma Inhibits the Proliferation of CAL-62 Cells through the ROS-Mediated PI3K/Akt/mTOR Signaling Pathway

Figure 5

CAP-induced apoptosis rates of CAL-62 cells in (a) control, (b) 15 s CAP-treated cells, (c) 30 s CAP-treated cells, and (d) 30 s CAP- and NAC-treated cells. In each small image, the lower left quadrant represents living cells, while the lower right quadrant and the upper right quadrant represent early and late apoptotic cells, respectively.
