Neural
stem cells (NSC) have been recognized as cellular vehicles for treatment of
invasive brain tumors. MRI is a unique non-invasive tool to monitor the
migration of stem cells labeled with MR contrast agents, such as
superparamagnetic iron oxide (SPIO) particles. Pervious studies have
confirmed that magnetosonoporation (MSP) can instantly labeled SPIO into stem
cells. The aim of this study was to validate the feasibility of MRI of
MSP-labeled NSC migration to gliomas in vivo.
