Table 2. Arterial GFP expression after stent-based delivery of Ad-GFP: morphometric results (anti-knob antibody- vs. D1-tethering for rat carotid stent reporter studies, mean ± SE).

Ad attachment strategy	Neointima	Media	Adventitia
PAA-BP/antibody/Ad-GFP stents	37.9 ± 20.3	6.8 ± 1.6	19.6 ± 5.6
PAA-BP/D1/Ad-GFP stents	23.0 ± 6.4	8.7 ± 4.5	16.4 ± 1.0

Data represent percentage of GFP-positive area relative to the total area of the respective compartment in microscopic sections.
