MRI of rat brain (IA 48 hr), SPIO-labeled hBM-MSCs directly grafted into a rat brain, and Prussian blue-stained cells and antimitochondrial-Prussian blue stained cells in a rat brain. A : Implanted cells are visualized as low signal intensity on SWI of MRI. B : Hypointense areas [square in (A)] represent massive invasions by Prussian blue stained cells (original magnification ×200, ×400). C : Graph showing the mean (±SE) number of engrafted cells in brain after either selective IA or IV transplantation (*p<0.05). D : Among these cells antimitochondrial-Prussian blue stained cells are noted (arrows, original magnification ×400). IA : intra-arterial, IV : intravenous, SPIO : superparamagnetic iron oxide, SWI : susceptibility weighted image, hBM-MSCs : human bone marrow-derived mesenchymal stem cells.
