This study describes the methods and results of superparamagnetic iron oxide nanoparticle (SPION) labeling and magnetic resonance imaging (MRI) tracking of human embryonic stem cell-derived photoreceptor precursors transplanted into the subretinal space of Royal College of Surgeons rats. SPION labeling and MRI tracking provide information about the biodistribution of transplanted photoreceptor precursors, which is necessary for improving the functional benefits of cell therapy for degenerative retinal diseases.

UI MeSH Term Description Entries
D008279 Magnetic Resonance Imaging Non-invasive method of demonstrating internal anatomy based on the principle that atomic nuclei in a strong magnetic field absorb pulses of radiofrequency energy and emit them as radiowaves which can be reconstructed into computerized images.
