Tenascin protein expression. (a) Representative frozen sections of carotid arteries harvested at 10 days and showing increased immunostaining in nontransgenic versus elafin-transgenic mice throughout the thickened media of the injured artery. (b) Tenascin calculated as a percent of total intima plus media area from six nontransgenic littermates and nine elafin-transgenic mice. Bars represent mean ± SEM. ^AP = 0.003 versus nontransgenic sham. ^BP = 0.005 versus elafin transgenic–injured arteries.
