Figure 1From: Mapping of oxidative stress responses of human tumor cells following photodynamic therapy using hexaminolevulinateSurvival fraction of cells was measured at 4 h after PDT when irradiation was performed with different light doses (A). Cell survival was measured at 1, 2 and 4 h after PDT with the light dose of 160 mJ/cm2 (B). Bars are SE based on three independent experiments with 3 parallels in each.Back to article page
