Plasma-activated medium (PAM) suppresses the migration and invasion abilities of ES2 cells. (A) Wound-healing assay at 0, 24 and 48 h after PAM treatment. (B) Transwell migration and invasion assay. Both migration and invasion abilities are calculated in comparison with the total seeded cells. (C) Proliferation assay for a total of 4 days. On each day, the Aqueous One Solution Cell Proliferation Assay reagent (Promega) is added for indication of cell number. (D) Colony-formation assay. Number of colonies was counted and compared to the total seeded cells. Three representative fields of cells in each group were captured and calculated, while one was selected for presentation in this study. Data are presented as mean ± SD. Three independent experiments with at least three replicates are performed. Statistics are shown as **P < 0.01.
