Tumorspheres formation ability evaluation on EMT-ACHN and EMT-786-0 cells. A: ACHN and EMT-ACHN tumorspheres, Bar = 50 μm; B: The tumorsphere number was counted and plotted, Percentage of tumorspheres with diameters < 50, 50-100, or > 100 μm were caculated and plotted; C: 786-0 and EMT-786-0 tumorspheres, Bar = 50 μm; D: The tumorsphere number was counted and plotted, Percentage of tumorspheres with diameters < 50, 50-100, or > 100 μm were calculated and plotted.
