Mesenchymal stem cells (MSCs) can be used for stem cell-based therapy containing AKI. Magnetic resonance imaging (MRI) is an ideal mean for stem cells tracking by labeling with superparamagnetic iron oxide (SPIO). Therefore, using the iron oxide-labeled mesenchymal stem cells (MSC) to treat the AKI and evaluating migration, distribution, and homing of cells by MRI is an ideal method for cell therapy and cell tracking \u003ci\u003ein vivo. Methods\u003c/i\u003e: \u003ci\u003eIn vitro\u003c/i\u003e, the MSCs were labeled with 25 μg/mL for 24 h, and test the labeled efficiency and cells viability. \u003ci\u003eIn vitro\u003c/i\u003e experiments, magnetic resonance imaging (MRI) measurement of non-labeled and SPIO-labeled MSCs (SPIO-MSCs) was performed in correlation to detectable cells concentrations and detectable time windows. \u003ci\u003eIn vivo\u003c/i\u003e experiments, MRI evaluation was performed before and after ischemic/reperfusion AKI (\u003ci\u003eN\u003c/i\u003e = 14) and intravenous injection of 5 × 10\u003csup\u003e5\u003c/sup\u003e SPIO-MSCs (\u003ci\u003eN\u003c/i\u003e = 10), PBS (\u003ci\u003eN = \u003c/i\u003e6) up to 8 days using a clinical 1.5 T scanner. Signal intensity of kidneys were measured and tested for statistical significance (unpaired Student’s \u003ci\u003et\u003c/i\u003e-test, \u003ci\u003ep \u0026lt; \u003c/i\u003e0.05) in comparison histology (hematoxylin and eosin [H\u0026amp;E], Prussian blue). \u003ci\u003eResults\u003c/i\u003e: \u003ci\u003eIn vitro\u003c/i\u003e, MSCs can be labeled with the SPIO without affecting the viability and labeling efficiency. SPIO-MSCs showed a reduction of signal intensity at T2WI and T2*WI, 5 × 10\u003csup\u003e4 \u003c/sup\u003ecells/mL, SPIO-MSCs were the minimum imaging cells concentration using a 1.5 T MR \u003ci\u003ein vitro. In vivo\u003c/i\u003e, SPIO-MSCs administration resulted in a T2*WI signal intensity decrease in renal medulla caused by SPIO-MSCs accumulation in contrast to control groups (\u003ci\u003ep \u0026lt; \u003c/i\u003e0.05) up to day 3 after transplantation, but T2*WI low signal intensity region of the renal medulla revealed an decrease at day 5, and no significant differences between SPIO-MSCs and control animals at day 8. \u003ci\u003eConclusion\u003c/i\u003e: Our data demonstrate that \u003ci\u003ein vitro\u003c/i\u003e and \u003ci\u003ein vivo\u003c/i\u003e, cell-tracking and monitoring of kidney distribution of intravenous injected SPIO-MSCs after AKI is feasible in MRI at 1.5 T.","descriptionType":"Abstract"}],"geoLocations":[],"fundingReferences":[],"xml":"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
