Title
In vivo monitoring of neural stem cells after transplantation in acute cerebral infarction with dual-modal MR imaging and optical imaging
Abstract

Stem cell therapies are promising strategies for the treatment of stroke. However, their clinical translation has not been fully realized due, in part, to insufficient ability to track stem cell migration and survival longitudinally over long periods of time in vivo. In this work, we synthesized a new class of manometer-sized cationic polymersomes loaded with superparamagnetic iron oxide nanoparticles and quantum dots for in vivo dual-modal imaging of stem cells. The results demonstrated that the synthesized cationic polymersomes can act as an effective and safety carrier to transfer image labels into neural stem cells, upon which the distribution and migration of grafted stem cells could be monitored by MR imaging up to 6 weeks and by fluorescence imaging within 4 weeks in the context of ischaemic brain injury. Cationic polymersomes hold great promise in the longitudinal monitoring of transplanted stem cells by using dual-modal MRI and optical imaging.
