To monitor the fate of transplanted cells within an organism, several non-invasive techniques have been introduced, including magnetic resonance imaging (MRI) of cells labeled with a contrast agent prior to grafting. Our previous study demonstrated a severe oxidative injury to lipids, proteins and the DNA of human bone marrow mesenchymal stem cells as a result of their labeling with superparamagnetic iron oxide nanoparticles (SPIONs). In searching for new contrast agents and magnetic cell labels, we prepared and tested a contrast agent based not only on Fe, but also on Co and Zn [cobalt zinc ferrite Co0.5Zn0.5Fe2O4+γ (CZF)] with a core encapsulated by amorphous silica.
