Co localization of the AT 1 and ET B receptors to vascular smooth muscle cells and endothelial cells. Immunostaining and co localization of the AT1 and ETB receptors to alpha-SMC and endothelin in resistance arteries of control patients. Antibodies to AT1 (green, A1, arrow) and smooth muscle actin (red, A2 arrow), A3 (merged A1 and A2). Antibodies to ETB (green, B1, arrow) and smooth muscle actin (red, B2, arrow), B3 (merged B1 and B2). Antibodies to AT1 (green, C1, arrow) and CD-31 (red, C2,arrow), C3 (merged C1+C2). Antibodies to ETB (green, D1, arrow) and CD-31 (red, D2, arrow), D3 (merged D1 and D2). Magnification × 400 for all photomicrographs.
