Fig. 1

Beas-2B cells were treated by simulated microgravity for 48 h first and then exposed to X-ray irradiation at indicated doses. a Cell survival fraction was determined by colony formation assay. b Cell survival curves were drawn for cells subjected to irradiation and/or simulated microgravity. The experiments were done in triplicate and error bars indicate SEM. IR, irradiation group; SMG, simulated microgravity group; SMG + IR, simulated microgravity combined with irradiation group. For the compounding treatment, cells were treated by simulated microgravity for 48 h first and then exposed to X-ray irradiation. Cells were cultured under 1 g during and after exposure (the same below). *Compared with control group. #Compared with IR group, */#p < 0.05, **/##p < 0.01, ***/###p < 0.001.
