Immunoblot analysis for AT2 receptors (AT2R; ■) and AT2R (□) expression in third generation uterine artery smooth muscle during ovine pregnancy. Immunoblots and summary densitometry are illustrated. There is no significant difference in AT1R or AT2R subtype expression across pregnancy or between nonpregnant and term pregnant vascular smooth muscle (P > 0.1, n = 4 in each group). Data are means ± SE.
