From: Stromal-epithelial responses to fractionated radiotherapy in a breast cancer microenvironment
Change in metabolic acidity for dosing protocols. Metabolic activity of MCF-7, MRC-5 and CAF cells measured over 5 days at different dose fractions in 2D culture. a MCF-7 cancer cell metabolic activity indicating radiation sensitivity. b MRC-5 metabolic activity and c CAFs metabolic activity showing more radio-resistant behavior than MRC-5 and MCF-7 cells. Error bars indicate one SEM. *indicates statistical significance at the p < 0.05 level based on ANOVA analysis
