cells (MSCs) are known to have a strong ability for homing. MSCs labeled with superparamagnetic iron oxide nanoparticles(SPIONs) exhibit enhanced homing due to magnetic attraction. We have designed a SPION that has a cluster core ofiron oxide-based nanoparticles coated with PLGA-Cy5.5. We optimized the nanoparticles for internalization to enable thetransport of PCS nanoparticles through endocytosis into MSCs. The migration of magnetized MSCs with SPION by staticmagnets was seen in vitro. The auditory hair cells do not regenerate once damaged, ototoxic mouse model was generated byadministration of kanamycin and furosemide. SPION labeled MSC’s were administered through different injection routes inthe ototoxic animal model. As result, the intratympanic administration group with magnet had the highest number of cells inthe brain followed by the liver, cochlea, and kidney as compared to those in the control groups. The synthesized PCS (polyclustered superparamagnetic iron oxide) nanoparticles, together with MSCs, by magnetic attraction, could synergisticallyenhance stem cell delivery.
