Low molecular weight alkyl-polycation wrapped magnetite nanoparticle clusters as MRI probes for stem cell labeling and in vivo imaging.

Abstract

Superparamagnetic iron oxide (SPIO) nanoparticles are potential probes for noninvasive cell tracking, but the design of safe probes coupled with high labeling efficiency is still an important objective for such application. In this study, an efficient SPIO probe has been developed for mesenchymal stem cells (MSCs) labeling and tracking. Different from many… (More)
