Objective:To investigate new photosensitizer chlorophyllin e6 mediated photodynamic effect on5637 bladder cancer cells,and discuss its potential mechanism.Method:Bladder cancer cells 5637 were incubated to logarithmic phase,and then chlorophyllin e6 was mixed into the culture medium.After the irradiation of 650-nm laser light,the growth inhibition rate was monitored by MTT assay and apoptosis of 5637 cells was detected by flow cytometry.Result:The growth inhibition rates of 2.5,5and 10μg/ml were 15.92%,43.1...
