From: Novel 89Zr cell labeling approach for PET-based cell trafficking studies
Representative PET images and biodistribution data of 89 Zr-labeled hMSCs and 89 Zr(HPO 4 ) 2 following intravenous injection. 89Zr-labeled human MSCs (2 × 105 cells with radioactivity concentration approximately 0.37 MBq/106 cells) and 89Zr(HPO4)2 (approximately 0.074 MBq radioactivity) were intravenously injected in athymic mice. Most of the radioactivity was distributed in the lung, liver, and bones following injection of 89Zr-labeled hMSCs whereas most of the radioactivity was distributed in the liver and bones following injection of 89Zr(HPO4)2. Values in graphs are shown as mean ± standard deviation, n = 3.
