FIG. 1.

Prussian blue staining of BM-SMCs (A) indicates successful uptake of SPIONs at all tested concentrations, as determined by the amount of blue stain around the pink-stained nucleus. LIVE/DEAD staining (B) shows no adverse effects of SPION-labeling on BM-SMCs, as confirmed by green fluorescence of viable cells. Scale bars = 100 μm. BM-SMCs, bone marrow mesenchymal stem cell-derived SMCs; SMCs, smooth muscle cells; SPION, super paramagnetic iron oxide nanoparticle. Color images available online at www.liebertpub.com/tec
