Fig 1. The effects of ionizing radiation on cell viability in human mast cells.

HMC-1(5C6) and LAD2 cells were exposed to various doses (0–1 Gy) of ionizing radiation and incubated for 72 h (A) or 14 days (B). Cell survival was evaluated using MTT assays (A) and colony formation assays (B). Data represent the mean ± SEM from five independent experiments performed in duplicate. * p < 0.05, # p < 0.05 versus the corresponding control group of HMC-1(5C6) and LAD2 cells, respectively.
