摘要：
A complex analysis of cytotoxicity was performed for a nanodispersed sol of cerium dioxide doped with gadolinium (Ce0.8Gd0.2O2-x) using a culture of mesenchymal stem cells. The absence of cyto- and genotoxicity over a wide range of concentrations (10(-5) - 10(-9) M) was demonstrated. At that, the highest concentration of Ce0.8Gd0.2O2-x nanoparticles (10(-4) M) was found to slightly reduce the activity of intracellular dehydrogenase, yet not leading to the development of apoptosis and further cell death. The obtained results confirm a high degree of Ce0.8Gd0.2O2-x nanoparticle biocompatibility, which opens prospects for their safe application as a contrasting agent in the magnetic resonance tomography.
