摘要Objective: Human induced pluripotent stem (iPS) cells exhibit great potential for generating functional human cells for medical therapies. In this paper, we report for use of human iPS cells labeled with lfuorescent magnetic nanoparticles (FMNPs) for targeted imaging and synergistic therapy of gastric cancer cellsin vivo. <br> Methods: Human iPS cells were prepared and cultured for 72 h. The culture medium was collected, and then was co-incubated with MGC803 cells. Cell viability was analyzed by the MTT method. FMNP-labeled human iPS cells were prepared and injected into gastric cancer-bearing nude mice. hTe mouse model was observed using a small-animal imaging system. hTe nude mice were irradiated under an external alternating magnetic ifeld and evaluated using an infrared thermal mapping instrument. Tumor sizes were measured weekly. <br> Results: iPS cells and the collected culture medium inhibited the growth of MGC803 cells. FMNP-labeled human iPS cells targeted and imaged gastric cancer cellsin vivo, as well as inhibited cancer growthin vivo through the external magnetic ifeld. <br> Conclusion: FMNP-labeled human iPS cells exhibit considerable potential in applications such as targeted dual-mode imaging and synergistic therapy for early gastric cancer.
