Figure 3. The situation of related protein indexes in THP-1 cells and the migration and invasion of A549 cells (hcc827 cells). (A) Protein indexes and statistics of Cathepsin K and Cathepsin L in THP-1 cells in each group. (B, D) Picture comparison and statistics of A549 cell (hcc827 cells) migration at 0 h and 48 h in the four groups. (C, E) Picture comparison and statistics of A549 cell (hcc827 cells) invasion in the four groups. (*P < 0.05; **P < 0.01).
