Magnetic targeting (MT) has been an emerging technology which is used to improve the delivery and retention of transplanted therapeutic cells in target site over the past 20 years. Meanwhile, stem cells have also been a research hotspot in cell therapy in recent years. Several researchers have combined the MT technology with Stem cell therapy in order to improve the efficacy. However, Different types of Magnetic Nano particles (MNPs) have presented different effects, and how to choose a proper MNPs became a question. This article aims to introduce the preparation method and application field of different types of magnetic Nanoparticles, discuss the pros and cons of different types of MNPs in stem cell therapy and make a prospect of MT technology in Stem cell therapy.
