Effects of low-dose PDT on the migration, invasion and tubular formation of HU-231 cells. (A and B) Horizontal migratory ability of the cells in the control, PDT, K02288 and PDT + K02288 groups at 0, 24 and 48 h (scale bars, 200 µm). (C and D) Vertical migratory ability of the cells in the control, PDT, K02288 and PDT + K02288 groups (scale bars, 200 µm). (E and F) Invasive ability of the cells in the control, PDT, K02288 and PDT + K02288 groups (scale bars, 200 µm). (G-J) Ability of the cells to form tubes in the control, PDT, K02288 and PDT + K02288 groups (scale bars, 200 µm). *P<0.05, **P<0.01, ***P<0.001 and ****P<0.0001. PDT, photodynamic therapy.
