Radiation response in spheroids. a, b Normalized CellTiter-Glo 3D cell viability assay after 13 days following radiation for spheroids of a HeLa and b LNCaP. c, d Normalized increase of diameter relative to starting size of c HeLa spheroids and d LNCaP spheroids over 13 days following radiation. Error bars are the 95% confidence interval from three independent experiments with at least 5 repeats per condition per experiment. ns indicates no significance, * indicates 0.01 < p < 0.05, ** indicates 0.001 < p < 0.01, *** indicates 0.0001 < p < 0.001, **** indicates p < 0.0001
