Monitoring ferumoxide-labelled neural progenitor cells and lesion evolution by magnetic resonance imaging in a model of cell transplantation in cerebral ischaemia [version 2; referees: 2 approved]
Efficacy of neural stem/progenitor cell (NPC) therapies after cerebral ischaemia could be better evaluated by monitoring migration and distribution of in vivo cells post-engraftment in parallel with analysis of lesion volume and functional recovery. Magnetic resonance imaging (MRI) is ideally placed to achieve this, but still poses several challenges. We show that combining the ferumoxide MRI c...

متن کاملPotential positive MRI contrast agent based on PVP-grafted superparamagnetic iron oxide nanoparticles with various repetition times
Objective(s): The present study aimed to evaluate the capability of synthesized and modified superparamagnetic iron oxide nanoparticles (SPIONs) as the positive contrast agent in magnetic resonance imaging (MRI) by investigating the effect of repetition time (TR) on the MRI signal intensity. Materials and Methods: SPIONs were synthesized using the co-precipitation method, and their surfac...
متن کاملHigh neuronal/astroglial differentiation plasticity of adult rat hippocampal neural stem/progenitor cells in response to the effects of embryonic and adult cerebrospinal fluids
Hippocampal neural stem/progenitor cells (hipp-NS/PCs) of the adult mammalian brain are important sources of neuronal and gial cell production. In this study, the main goal is to investigate the plasticity of these cells in neuronal/astroglial differentiations. To this end, the differentiation of the hipp-NS/PCs isolated from 3-month-old Wistar rats was investigated in response to the embryonic...
متن کاملIn vivo magnetic resonance imaging of endogenous neuroblasts labelled with a ferumoxide-polycation complex
Neurogenesis occurs at the subependymal zone (SEZ) of the adult brain. Neural progenitor cells give rise to neuroblasts, which migrate to the olfactory bulb (OB) via the rostral migratory stream (RMS). Development of methods capable of labelling and tracking these cells in vivo would be of great benefit to the understanding of neuroblast migration away from the SEZ under normal and pathological...
