Fig. 5From: Comparative study of the effects of different radiation qualities on normal human breast cellsSphere formation after irradiation. Change of the sphere formation ability of MCF10A cells at different time points after exposure to X-rays and neutrons with respect to individual 0 Gy control per day (=100% baseline). Data from three independent experiments are presented as mean values ± SEM. Significances refer to the individual 0 Gy control of each radiation quality per day. Asterisks illustrate significances: *p < 0.02, **p < 0.01, ***p < 0.002. (HDR, high dose rate; LDR, low dose rate)Back to article page
