Capillary endothelium function
WebTight junctions (TJs) between the endothelium play an important role in the acellular permeability of the endothelial barrier. 5 The TJs in endothelial cells are composed of occludin, claudins and zonula occludens (ZO-1, ZO-2, and ZO-3), 6 which interact to seal the intercellular space and maintain vascular homeostasis. 7 A lot of evidence ...

WebLymphatic capillaries consist of: Endothelial cells, which line the capillary walls. Basement membrane, which supports the endothelial cells. Mini-valves, which let lymph flow into the capillaries but not out of them. Anchoring filaments, which contain elastic fibers and attach the endothelial cells to fibroblast cells in connective tissue. WebMost capillaries are about 3 or 4 micrometers (about the size of a thread in a spider web). They have two layers of cells. The cells on the inside layer of the capillary are endothelial cells. The outside layer has epithelial cells. Providers also call this layer the basement membrane. Fenestrated capillaries have tiny pores in their inner layer.
