Fraction of damaged cells after microbeam irradiation at the periphery of a human urothelial explant outgrowth. A total of 10 cells were irradiated at the edge of each explant (10 3He2+ particles per cell). Samples were fixed, stained and scored on day 3 after irradiation. Error bars represent standard deviation of the means. Each sample was from a separate donor ureter.
