The Effect of Superparamagnetic Iron Oxide with iRGD Peptide on the Labeling of Pancreatic Cancer Cells In Vitro: A Preliminary Study

Figure 4

The evaluation of the mean signal reduction values ( ) for different iron concentrations. For the iron concentration of 12.6 μg/mL, a significant difference was found between the treatment and control groups ( ). For the iron concentration of 14.7 μg/mL, a significant difference was only found between 0.25 μg/mL iRGD and the control group. (A)–(E) indicate 8.4–21 μg/mL iron ion concentration. The SPIO group served as the control group. .
