Endothelial progenitor cells (EPCs) were collected from human cord blood and genetically modified to carry sodium human iodide symporter (hNIS) gene. Transgenic and control EPCs were magnetically labeled and administered systemically or locally in human glioma bearing rats. Migration and expression of hNIS in glioma were monitored by MRI and Tc-99m SPECT imaging, respectively. Both MRI and Tc-99-SPECT were able to track the migration and accumulation of systemically and locally administered EPCs in glioma. Expression of hNIS was detected by Tc-99m activity. EPcs can be used as imaging probe and gene carrier.
