In vitro validation of SPIO labeling of mOct4 BM-MAPCs. a ICP-OES data showed superior labeling of mOct4 BM-MAPCs using ihSPIO particles compared to labeling using Endorem® with unlabeled cells containing 1.3 ± 0.8 pg Fe/cell, ihSPIO-labeled mOct4- BM-MAPCs containing 15.9 ± 1.5 pg Fe/cell and Endorem®-labeled mOct4 BM-MAPCs 8.2 ± 0.6 pg Fe/cell. b An MRI phantom confirmed these results and showed the corresponding in vitro contrast generation caused by the presence of iron in the cells with enhanced signal decay corresponding to higher concentrations of iron/cell. c BLI using D-Luciferin as a substrate indicated no marked differences in cell viability between labeled and unlabeled cells.
