Distribution and amount of fluorescein-labeled BMMSCs in the different groups assessed by in vivo imaging.
(a) In the ultrasound group, the fluorescein-labeled BMSCs were mainly found in the lung tissue (thin arrow) and epigastrium. (b) In the BMMSCs group, the fluorescein-labeled BMMSCs were found in the lung tissue (thin arrow). (c) In the MMUS group, more of the fluorescein-labeled BMMSCs were found in the prostate tissue than in the other groups (thick arrow).
