BK elevated hCPCs survival rate and revascularization in MI heart. A ELISA assay showed the concentration of bradykinin in sham and MI rats. B RT-qPCR detection showed the human-specific gene expression in rat hearts at 24 h, 48 h, 72 h, 7 days, and 42 days after transplantation in different groups. C Representative of fluorescence images of c-kit and Ki67 in the border area of MI rat hearts after transplanted 24 h. Representative of fluorescence (D) images and quantitative analysis (E) of CD31 in the border area of MI hearts 42 days after transplanted with different cells. (Data are shown as mean ± SEM, n = 6, *P < 0.05, **P < 0.01 VS. MI; #P < 0.05, ##P < 0.01 VS. CPCs-MI)
