Fluorescent imaging of FMNP-labeled MSCs targeting gastric cancer cellsin vivo. (A) The in vivo fluorescent images show that tumor sites of the mice in the test group had fluorescent signals after post-injection of FMNP-labeled MSCs at 7 and 14 days (right), and tumor sites of the mice in the control group had no fluorescent signal after post-injection of FMNPs at 7 and 14 days (left). (B) The fluorescent imaging of major organs show that no signal was detected in the tumor and organs of the control group (left), and obviously fluorescent signals were detected in the tumor tissues of the test group (right).
