Micrographs showing immunostained capillaries from patients with idiopathic menorrhagia at ×40 magnification. (A) Angiopoietin-1 positive vessel, with a brim of diaminobenzidine tetrahydrochloride staining on the luminal side of the vessel. Background staining was performed with hematoxylin. (B) Angiopoietin-2 positive vessel with diaminobenzidine tetrahydrochloride stain in endothelial cells as well as in adjacent, abluminal cells. The arrow points at the vessel. (C) Tie-2 staining, similarly located as in B. (D) Double staining and imaging with confocal microscopy. The section was stained with antibodies to CD34 (in red) and to smooth muscle actin-α (in green). This overlay shows the green pericytes with typical projections on the abluminal side of the endothelial cells, but with some overlap (yellow). The arrow points at a gap, not stained for CD34. (E–G) Double staining and imaging with confocal microscopy. The section was stained with antibodies to tie-2 (in green, E) and to CD34 (in red, F), and the overlay (G) shows that the green stain partly covers areas abluminal of the endothelial cells. The arrow points at a gap, not stained for CD34.
