| Research Abstract |
In-vivo tracking of transplanted Mn2+-labeled cells with Magnetic Resonance Imaging (MRI) was attempted to visualize the localization of migrated cells at high spatial resolution in stroke model rat and the long term regenerative therapeutic effects. Repeat measurement of MRI showed that transplanted peripheral mononuclear cells (MNCs) spread actively and concentrically in sham-operated rats. However, MNCs spread in ellipse and move faster to ischemic lesion in stroke model rats. In addition, stroke model rats revealed higher blood pressure in 3 weeks than in 2 weeks after cell transplantation. Mn2+-labeling and MRI are useful for cell selection, cell delivery, and assessment of therapeutic effect.
