Cell counting of Mel270 (A) and BLM (B) cells performed 20 and 40 days after treatment with proton beam radiation or X-rays. Cells were irradiated, cultured at standard conditions and then seeded at 20 and 40 days post-treatment and the assay was conducted during five next days. Experiment was performed in triplicate and for every repetition, cells from 4 wells were counted. Results are presented as the percent of the untreated control. Mean values ± SEM. #p < 0.05; *p < 0.01; **p < 0.001.
