Miniature Dielectric Barrier Discharge Nonthermal Plasma Induces Apoptosis in Lung Cancer Cells and Inhibits Cell Migration

Figure 8

Cell migration is inhibited by plasma. (a) Control and 15 sec treated samples on days 0, 1, 2, and 3. Yellow circles on both 15 sec and control samples mark the clearance zone on each day. Blue circles on day 3 represent the initial day 0 clearance zone. (b) Normalized cumulative cell coverage based on initial clearance zone on day 0. Control images are stitched. Scale bars are 200 μm. Data are the mean percentage of area covered ± SD of three independent experiments run in triplicate. , , and denote statistically significant differences between control and 15 sec at days 1, 2, and 3, respectively ().
