(A) The apoptosis test of U251 cells. (B) The apoptosis rate of U251 cells. U251 cells were subjected to different treatments for 24 h; flow cytometry detected apoptotic rates in each group. The apoptotic rate of U251 cells in the FUS + GA/PLGA group was 75.97 ± 0.49% (***p < 0.001 versus the control group and $$$ p < 0.001 versus the GA/PLGA group).
