Figure 1

Characterization of LL/2 cell vaccine co-expression IL-18 and GM-CSF. (A) The GFP fluorescent images represents transfection efficiency of LL/2 transfected with freeze-drying cationic liposome-GFP. (B) Cell morphology was imaged at 24 h and 72 h before or after irradiation, respectively (original magnification, ×200). The proliferation of LL/2 cell was measured by MTT at 24 h, 48 h and 72 h before or after irradiation, respectively (P < 0.01). (C) The secretion of IL-18 and GM-CSF in cell supernatant was detected by ELISA between before irradiation and after irradiation (P > 0.05), respectively. Columns represents mean; bars represents SD.
