Figure 3. ES-GFP gene transfer suppresses HREC growth. Mean cell numbers were assessed for 5 consecutive days. Transfection with embryonic stem-green fluorescent protein (ES-GFP) using ultrasound-targeted cationic microbubble destruction caused a significant decrease in the human retinal vascular endothelial cell (HREC) cell viability rate compared with the other groups. (* p<0.05 relative to the control and cationic microbubble (CMB) groups, #p<0.01 relative to the control in every time point; n=6 per group).
