Intracellular iron observation. Prussian blue staining (a) and transmission electron microscopy (b) showed a large amount of intracytoplasmic iron particles in the MTMSCs-PEG3-FTH1, MSCs-CMV-FTH1, and MTMSCs-CMV-FTH1 but not in the MSCs, MTMSCs, or MSCs-PEG3-FTH1. Quantification of the intracellular iron content (c) showed that the iron content was significantly higher in MTMSCs-PEG3-FTH1 than in MSCs-PEG3-FTH1 (***P<0.001). There was no difference between the MTMSC-CMV-FTH1 and MSC-CMV-FTH1 groups or between the MTMSC and MSC groups
