Radiotoxicity clonogenic assays in MIA-Paca2 cancer cells seeded in 6-well plates. (A) Surface area measurement comparison between intermittent exposure to 10% CO2 and 5% CO2 controls (Mean ±SEM). Statistical significance (P<0.05) noted at 0 Gy and 2 Gy of radiation dose. (B) Normalized daily growth trends in response to ionizing radiation comparing 10% CO2 intermittent, 10% CO2 continuous and 5% CO2 continuous exposures.
