Characterization of CBC3T-1 cell behavior. a Representative images of CBC3T-1 spheres were obtained on days 1, 7, and 14. b, c Wound-healing assays at 12 and 24 h after scratching (N = 3). d–g Transwell assays were used to examine the cell migration and invasion capacity of CBC3T-1 and TFK-1 cells (N = 3). h, i Representative images showing colony formation (N = 3).
