Figure 7.

Confocal microphotograph of myocardial tissue of mice after treatment to show the efficiency of gene transfection in vivo by UTMD. 5 days after the treatment of UTMD in the myocardial tissue of mice, the samples were immunostained with an antibody against green fluorescent protein (GFP, green), nuclear staining (Hoechst, blue). A ~ C: control group, the mice was injected with empty plasmids; D ~ I: GFP group, the mice was injected with plasmids expressing GFP; G ~ I: the merged images indicated co-localization of GFP and Hoechst. Magnification _400 in A to F. Framed areas in D to F are shown enlarged at _600 in G to I[41].
