In this study, an closed cell labeling system was designed to reduce contamination and be efficient for clinical applications, using focused ultrasound, and one experiment was conducted to validated the feasibility of the magnetosonoporation (MSP) cell labeling apparatus. The results indicated that MSP is an instant, safe and efficient magnetic cell labeling technique for non-invasive MRI stem cell tracking in vivo and the design of MSP apparatus was beneficial to reduce cell contamination potential and convenient for future clinical applications.
