Thermal incubation of 5-ALA increased ROS generation in A431 and SCC-13 cells. (A) SCC-13 and (B) A431 cells thermally incubated with 5-ALA for thirty minutes followed by 1000 seconds of blue lights increased ROS generation. Error bars represent mean ± standard error of the mean; *P < 0.05 compared to 0 mM control.
