Figure 1.
Schematic representation of the sequence of procedures (sequence indicated by numbers) used to treat cells (irradiation, hyperthermia, irradiation + hyperthermia) and prepare them for analysis. Control (unheated, unirradiated) cells were kept in CO2-incubator at 37 °C, while heating of cells (unirradiated and irradiated) was done in a water bath for 2 h at 41.5°C or 42.5°C.
