Inhibition of Neointimal Hyperplasia. Quantitative analysis from light microscopy images 14 days after implantation after polymethacrylate embedding of sections (A). Light microscopy images of rabbit iliac arterial tissue cross-sections after two weeks of control and endothelial nitric oxide synthase (eNOS)-expressing plasmid DNA-loaded stent implantation. Polymethacrylate-embedded 10 μm-thick arterial vessel sections were stained with Verhoffs elastin stain and counter stained with Van Giesons stain for measurement of neointimal-to-medial thickness ratios. Images were taken at 4× and 10× magnification (B).
