Abstract
The relative sensitivities of different tumor cells to photodynamic therapy (PDT) with benzoporphyrin derivative monoacid ring A (BPD-MA) were compared in the four tumor cells. A good correlation was observed between the cell survival at 0.1 μg/ml of BPD-MA and sensitizer uptake/106 cells (r = −0.99) or the plating efficiency of cells (r = 0.99). At 3 h after the irradiation, a significant difference was observed in the proportion of apoptotic cells among the four tumor cells (p = 0.024). In conclusion, cell responses to PDT depend on the several factors such as the cell line, photosensitizer dose, and fluence.
