Ultrasound-Targeted Microbubble Destruction Improves the Migration and Homing of Mesenchymal Stem Cells after Myocardial Infarction by Upregulating SDF-1/CXCR4: A Pilot Study

Figure 4

Cell surface expression of CXCR4 using FCM. (a) Representative examples of the membrane expression levels of CXCR4 on MSCs in the supernatant of the different groups. The percentage of MSCs positive for surface CXCR4 protein expression was valued as the number of cells expressing surface CXCR4/number of cells in total. (b) Quantification of cell surface CXCR4 protein expression in the supernatant groups. (c) Quantification of cell surface CXCR4 protein expression in the MTE groups. All values are expressed as the mean ± SD. ; .
