Fig. 7From: MRI detection of the malignant transformation of stem cells through reporter gene expression driven by a tumor-specific promoterMRI of xenografts. The T2WI signal intensity (a) and T2 value (b) of masses were significantly decreased in the MTMSC-PEG3-FTH1 and MTMSC-CMV-FTH1 groups compared with the MTMSC group. There was no significant difference in the T2 value between the MTMSC-PEG3-FTH1 group and the MTMSC-CMV-FTH1 groupBack to article page
