Scanning micrographs showing intact (A) and damaged (B) mesothelium. Bars = 10 μm. Damage of the mesothelium results in exposure of the basement membrane.

Adherence of endometrial fragments to peritoneum. (A), Scanning micrograph showing an endometrial fragment adherent to a damaged area of the peritoneum (Bar = 10 μm). (B), Light micrograph of 1-μm cross-sections of epon-embedded peritoneum of the mesothelium and underlying layers with adhering endometrial fragments, stained with toluine blue. Transmission micrographs of this area show that adhesion to the peritoneum occurs only at locations where the mesothelial lining was impaired (C) (Bar = 5 μm). EF = endometrial fragment; M = mesothelial cells/mesothelium; ECM = extracellular matrix.
