Abstract
One major challenge in stem cell therapy is to longitudinally track cell fate after cells transplantation. Molecular Imaging approaches enabling noninvasive long-term monitoring the transplanted cells are imperative for assessment of the safety and efficiency. Here, we used PiggyBac technology to insert triple reporter genes: NIS, EGFP and Firefly luciferase into a human embryonic stem cell line (hESCs, H9) and obtained a reporter hESCs line (NIS-EGFP-Fluc H9). The triple-reporters allows the transplanted NIS-EGFP-Fluc H9 cells and their derivates to be fluorescence, bioluminescence and even PET/SPECT imaged. This triple-reporter hESCs line provides a valuable imaging platform for cell-based therapeutics clinical translation.
