Optimal Labeling Dose, Labeling Time, and Magnetic Resonance Imaging Detection Limits of Ultrasmall Superparamagnetic Iron-Oxide Nanoparticle Labeled Mesenchymal Stromal Cells

<table>Cellular iron content. The iron content per cell was determined in unlabeled MSC and MSC incubated with half or full dose USPIO for 2, 6, and 21 hours. MSC: mesenchymal stromal cells. USPIO: ultrasmall superparamagnetic iron-oxide. USPIO dose—full: 10 <i>μ</i>g per 10<sup>5</sup> cells; half: 5 <i>μ</i>g per 10<sup>5</sup> cells.</table>
