Superparamagnetic iron oxide nanoparticles (SPIO) have diverse applications in biomedicine, and have been used for cell tracking of mesenchymal stem cells (MSCs) within the body using MRI. SPIO labelled MSCs will home to and incorporate themselves within lung metastases in vivo, carrying SPIO particles into tumours. The application of an alternating magnetic field causes rapid heating of the SPIO, damaging the surrounding cancer cells. In this study we investigate the potential of SPIO as bifunctional nanoparticles for hyperthermia treatment in a subcutaneous murine tumour model and the possibility of MR monitoring of SPIO labelled MSCs within the tumour.
