Migration of U87 cells after ALA/light treatment in the absence vs. presence of an iNOS inhibitor. Cells were grown to ~90% confluency, sensitized, and irradiated in the absence or presence of 1400W (25 μM). After irradiation, a 200-μl pipet tip was used to make a scratch across each cell layer. Immediately thereafter and 24 h later, the cells were photographed. Extent of gap closure at each time point was determined using the expression given in the Methods section. Numbers are means ± SD of values from at least 4 experiments.
