Figure 4

(A,B) A2780 cells were treated with TTFields for 72 hours. (A) Effect of TTFields treatment on number of A2780 cells. (B) Clonogenic survival of A2780 cells following TTFields treatment. (C,D) In a separate experiment, U-87 MG cells were treated with TTFields for 144 hours. (C) Effect of TTFields treatment on number of U-87 MG cells. (D) Clonogenic survival of U-87 MG cells following TTFields treatment. 0.05 > *p > 0.01, **p < 0.01, and ***p < 0.001 from control group.
