Others of the endothelial cells show a great tendency to form muscle fibres.
There is further a great tendency for the endothelial cells to form muscles, and this is especially pronounced in the small arm-sinus, where a conspicuous muscle is built up. The mantle-sinuses which form the chief spaces in the mantle are diverticula of the main coelomic cavity.
Melanine particles formed in the spleen in malaria, which pass along with the blood through the liver, are appropriated by the endothelial cells of the hepatic capillaries, and are found embedded within their substance.
Heidenhain, on the other hand, rejected entirely the filtration view of lymph-formation, believing that the passage of lymph across the capillary wall is a true secretion brought about by the secretory function of the endothelial plates.
Heidenhain recognizes two classes, first, such substances as peptone, leech extract and crayfish extract; and, secondly, crystalloids such as sugar, salt, &c. Starling sees no reason to believe that members of either class act otherwise than by increasing the pressure in the capillaries or by injuring the endothelial wall.
the labial tentacles and walls of the gut - very fine vessels with endothelial cell-lining are found.
The arteries and veins have proper endothelial walls; they pass abruptly into the sinuses and in some cases communication is effected by orifices in the walls of the vessels, as for example in the vena cava of Nautilus.
Heart and blood-vessels are entirely absent; the blood is contained in sinuses which have no distinct walls or endothelial lining, and the principal of which are the perianal, the pedal, the visceral and the pallial.
This enzyme catalyzes the conversion of angiotensin I to angiotensin II in blood plasma and in vascular endothelial tissues and degrades bradykinin.
catechin levels did not correlate with changes in endothelial function, plasma markers of oxidative stress, or C-reactive protein.
TSP is also found in monocytes and endothelial cells and it binds to heparin, fibronectin and collagen (Lawler, 1986 ).
The potent angiogenic cytokine vascular endothelial growth factor (VEGF) appears to play a role in this process (Ref.
Recent studies have shown that passive smoking may be associated with vascular endothelial dysfunction.
Abstract Objective To clarify the role played by endothelial cell production of fibrinolytic factors in normal pregnancy and pre- eclampsia.
The tunica intima has an endothelium of flattened endothelial cells.
We have previously shown that cigarette smoking is associated with endothelial dysfunction and impaired endogenous fibrinolysis.
Genes regulated by hypoxia are being studied in a range of endothelial and other cell types.
intercellular junctions with endothelial cells.
thymidine phosphorylase (platelet-derived endothelial cell growth factor) is one such factor.
Figure 1 Sequence alignment of human platelet-derived endothelial cell growth factor (PD-ECGF) and E. coli thymidine phosphorylase (TP ).
sprouting endothelial buds: hence the association with a favorable outcome.
An enzyme in endothelial cells called JNK is involved in causing increased stickiness by some inflammatory agents.
These are called high endothelial venules (HEVs) (see the picture below ).
Some of the endothelial cells lining the coelom are ciliated, the cilia keeping the corpusculated fluid contents in movement.
The members of the first class influence the endothelial plates of the capillaries injuriously, inducing thereby increased permeability; those of the second class (sugar, &c.), on injection into the blood, attract water from the tissues and cause a condition of hydraemic plethora with increased capillary pressure.
The granules were of course the sprouting endothelial buds: hence the association with a favorable outcome.
Changes in the pattern of distribution of von Willebrand factor in rat aortic endothelial cells following thrombin generation in vivo.
For example, VEGF promotes endothelial cell migration and tubule formation.
B. Venous valves are folds of tissue formed from the endothelial lining of the tunica intima.
These are called high endothelial venules (HEVs) (see the picture below).
Damage also occurs to the endothelial cells that line the blood vessels.
Hypoxia, blood clots, and endothelial damage lead, in turn, to the release of inflammatory mediators.
Endothelial cells-The cells lining the inner walls of a body cavity or the cardiovascular system.
