Fenestrated Capillaries in the Human Parietal Peritoneum and Rabbit Diaphragmatic Peritoneum
Fenestrated capillaries account for 1.7% microvessels examined under electron microscopy in only one of 20 human peritoneal samples examined. The fenestrae were closed by diaphragms 70 Å thick. In New Zealand white rabbits fenestrae were seen in 3.2% of observed capillaries, with diaphragms 60 Å to 90 Å thick. The glycocalix covering the fenestrae diaphragms may limit the passage of anionic blood components, particularly proteins, as has been demonstrated in other studies.
