Cell viability in light and dark conditions according to methyl pheophorbide A treatment for U937 cells (A) and SK-HEP-1 cells (B). The cells were seeded at a density of 2 × 105 cells/ml in 96 well white plate. After 4 h of incubation, the methyl pheophorbide A was treated at a concentration of 0.25, 0.50, 1.00, and 2.00 μg/ml. After inducing photodynamic activity, cells were mixed with an equal amount of CellTiter-Glo 2.0 reagent for 10 min. Luminescence was measured with a GloMax™ multi microplate multimode reader. All experiments were conducted with three replicates, and the results were expressed as mean ± SD (standard deviation). Values were significantly different both by treatment and light with two-way ANOVA (p < 0.05). Different letters represent p-values between light and dark conditions by Post hoc Duncan’s multiple range test
