Endothelial cells resemble those in lymphatic capillaries in that they show microvillus-like processes or folds projecting into the lumen and also have extremely attenuated and fenestrated cytoplasm except in the nuclear region. Numerous pinocytotic vesicles, bundles of filaments and many electrondense ...
9.1). The resulting tubular, single-cell-thick, “cobblestone” arrangement of endothelial cells comprises the arterioles, venules, and capillaries of the CNS. These cells house the proteins that maintain a physical and biochemical barrier between blood and brain. Paracellular transit of polar ...
Discontinuous endothelium is found in the sinusoids of the liver, spleen, and bone marrow [3]. Other morphologic differences are seen in the size and thickness of ECs. Aortic ECs are 1 µm thick compared to the cells of capillaries, which are 0.1 µm thick, and veinous ECs are 0.1...
Capillaries are the gateway through which all circulating energy substrates and hormones must pass to support the metabolic functions of the surrounding “end-user” parenchymal cells. The junctions between adjacent ECs in continuous capillaries restrict the movement of large molecules between plasma and ...

It also allows for smooth vessel regulation, inflammation control, and initiation of immune response to pathogens. Where are your endothelial cells? The endothelial cells are located in the lining of the cardiovascular system (arteries, veins, and capillaries) and in the vessels of the lymphatic ...

Pulmonary endothelial progenitor cells (EPCs) are critical for neonatal lung angiogenesis and represent a subset of general capillary cells (gCAPs). Molecular mechanisms through which EPCs stimulate lung angiogenesis are unknown. Herein, we used single-c
Early in the disease process, typical vascular symptoms, e.g., Raynaud’s phenomenon precede tissue fibrosis suggesting that microvascular injuries and dysfunctions involving the vascular endothelial cells (VECs) and capillaries are the initial event [9]. This clinical observation led to the conclusion...
