Preventive effect of pTRG from the second challenge of CT-26 cell growth in the lungs. After the first tumor therapy, the surviving mice were subjected to a second challenge with an intravenous injection of 0.7 × 106 of CT-26-iRFP on the 30th day after the first tumor injection. A Survival rates of the mice were monitored (n = 5 per group). B Fluorescence images of CT-26-iRFP on day 10 after the second CT-26 challenge (n = 6). C Representative photographs of metastatic lung cancer (n = 6). D Tumor infiltration was analyzed via hematoxylin and eosin (H&E) staining of the lung tissue (n = 6)
