α-Actin expression. (a) Representative frozen sections of injured and sham-operated carotid arteries harvested at 10 days and showing decreased immunostaining especially in the thickest part of the vessel wall in the nontransgenic-injured artery. (b) Area immunostained for actin was calculated as a percent of total intima plus media area. Bars represent mean ± SEM from six nontransgenic littermates and nine elafin-transgenic mice. ^AP = 0.0002 versus nontransgenic sham. ^BP = 0.0015 versus elafin transgenic–injured arteries.
