Figure 3.
Effect of Ad-FasL on neointimal formation in rat carotid arteries 2 weeks after balloon injury. (A) Representative cross sections from arteries treated with either saline or Ad-FasL (1 × 108 pfu) at the time of injury. Cross sections were stained with Richardson’s combination elastic tissue trichrome stain (Upper) or with hematoxylin and eosin (Lower). Arrows indicate the internal elastic lamina. (B) Intimal (open bar) and medial (shaded bar) areas of carotid artery cross sections at 2 weeks after injury (n = 5 arteries for each group). The intimal/medial area ratio is reported in parentheses above the bars.
