Effects of 10 μM AGP or ROSI on neointima induced by balloon injury of the rat carotid artery. Panel A: Intima-to-media ratios three weeks after balloon injury followed by a one-hour treatment with vehicle, 10 μM AGP or ROSI. Panels B, C, and D show representative cross sections of vehicle-, AGP-, and ROSI-treated carotid arteries. The calibration bar is 200 μm.
