Figure 11. CTSL2 promoted cell proliferation and migration of LUAD cells. (A) CCK-8 proliferation curve of A549 cells; (B) Co-staining of calcein AM and PI of A549 cells, the live cells were stained with green fluorescence, and the dead cells were stained with red fluorescence; (C) Percentage of dead cells in different groups; (D) Colony formation of A549 cells; (E) Relative number of colonies in different groups; (F) Cell migration of A549 cells during 24 h; (G) Migration distance in different groups. *P < 0.05, **P < 0.01. All the experiments were repeated for three times.
