Stem cell transplantation is being explored as a new paradigm for the treatment of demyelinating diseases.

Magnetically labeled multipotential neural precursor cells were transplanted into the ventricles of rats with acute experimental allergic encephalomyelitis (EAE) and high-resolution (microscopic) MR images were obtained ex vivo.

Migration patterns of live cells into periventricular white matter structures could be easily visualized, with a good correlation of the corresponding histopathology.

The present results confirm that MR cell tracking can be used to guide the development of successful transplantation protocols.
