In vivo migration of THP-1-IO. MR images of A549 subcutaneous tumors after an injection of THP-1-IO intravenously. (a) Tumors contained IO, and the volume of IO detected was gradually increased followed with an increasing dose of irradiation. Numbers indicate individual samples. (b) IO was detected by Prussian blue staining (arrows) in a tumor from mice injected THP-IO. (c) The time frame indicates MR imaging schedule. Calibration bar = 500  𝜇 m.
