Flow cytometry fluorescence intensity graphs. a Group 1, 20 min after the medium exchange with 1 h of 5-aminolevulinic acid (5-ALA) exposure. High peak represents viable cells, accounting for 89% of myxofibrosarcoma (MUG-Myx1) cells (blue). Low peak represents unresponsive or dead cells, accounting for 11% of MUG-Myx1 cells. b Group 2, 20 min after the medium exchange with 3 h of 5-ALA exposure. High peak drops to 76% of MUG-Myx1 cells. Low peak increases to 25% of MUG-Myx1 cells. c Group 3, 1 h after the medium exchange with 3 h of 5-ALA exposure. High peak drops to 60% of MUG-Myx1 cells. Low peak increases to 40% of MUG-Myx1 cells. Human adipose-derived stromal cell peaks (red) remain unchanged
