Fig. 6. Morphological changes of Golgi apparatus after oxidative stress upon PDT treatment.
Morphological changes of GA observed by (a–f) CLSM (stained with Gogli Green) and TEM (g–o) imaging in HeLa cells after treatment with light only, TPE-PyT-CPS (0.2 μM) with or without light irradiation (25 mW cm−2, 2 min). The experiments were performed three times independently, representative images are shown. Scale bars for a–c: 10 μm; d–f: 5 μm; g–i: 2 μm; j–l: 1 μm; m–o: 0.5 μm.
