Microbubble-enhanced ultrasound exposure improves gene transfer in vascular endothelial cells

Figure 2 Experimental setup for the ultrasound exposure. Ultrasound probe with transmission gel was placed on the cell suspension covered with polyester film, a 24-well plate covered by a 6-μm polyester film was kept in a water bath at 37°C, and also a sponge mat was placed in the water bath.
