131I radiotherapy in cancer cells treated with EVs. Huh7 liver cancer cells were incubated for 48 h with vehicle (null), 10 µg of control EVs, or 10 µg of EVs derived from Huh7/NIS-Adv donor cells. The cells then underwent radiotherapy with 20 or 40 µCi of 131I for 7 h and were assessed for survival. Data are mean ± SD of % survival obtained from triplicate samples per group. **P < 0.01; ‡P < 0.001 compared to untreated controls for each group.
