(A-D) - Flow cytometry results. Normalized histograms obtained by flow cytometry 48 hours after irradiation at several doses, with MBRT (left) and BB (right). The plots correspond to: (A) the unstained surviving cells, (B) the positive green fluorescence cells, corresponding to those cells undergoing apoptosis in an early stage, (C) double stained cells, with propidium iodide and annexin, indicating as late apoptotic as necrotic dead cells, and (D) the early (in green) and late (in green and red) apoptotic cells, in order to represent altogether the different death processes.
