TTFields harness physics to disrupt mitosis in cancer cells1-3
In preclinical models, TTFields have been shown to disrupt mitosis in cancer cells by exerting electric forces on their polar components (eg, microtubule spindle formation during mitosis), disrupting their normal localization (place in cell membrane) and function, ultimately leading to cell death.1-3
