Fig. 4From: MRI detection of the malignant transformation of stem cells through reporter gene expression driven by a tumor-specific promoterCellular FTH1 expression before and after malignant transformation. Western blotting (a) and quantitative analysis (b) showed that the FTH1 expression in the MTMSCs-PEG3-FTH1 was significantly higher than that in the MSCs-PEG3-FTH1 (***P<0.001). However, there was no significant difference in FTH1 expression between the MTMSCs and MSCs or between the MTMSCs-CMV-FTH1 and MSCs-CMV-FTH1Back to article page
