## Abstract As the complex pathogenesis of multiple sclerosis contributes to spatiotemporal variations in the trophic micromilieu of the central nervous system, the optimal intervention period for cell‐replacement therapy must be systematically defined. We applied serial, 3D high‐resolution magnetic resonance imaging to transplanted neural precursor cells (NPCs) labeled with superparamagnetic iron oxide nanoparticles and 5‐bromo‐2‐deoxyuridine, and compared the migration pattern of NPCs in acute inflamed (__n__ = 10) versus chronic demyelinated (__n__ = 9) brains of mice induced with experimental allergic encephalomyelitis (EAE). Serial in vivo and ex‐vivo 3D magnetic resonance imaging revealed that NPCs migrated 2.5 ± 1.3 mm along the corpus callosum in acute EAE. In chronic EAE, cell migration was slightly reduced (2.3 ± 1.3 mm) and only occurred in the lateral side of transplantation. Surprisingly, in 6/10 acute EAE brains, NPCs were found to migrate in a radial pattern along RECA‐1^+^ cortical blood vessels, in a pattern hitherto only reported for migrating glioblastoma cells. This striking radial biodistribution pattern was not detected in either chronic EAE or disease‐free co
