The endothelial glycocalyx promotes homogenous blood flow distribution within the microvasculature.
Many common diseases involve impaired tissue perfusion, and heterogeneous distribution of blood flow in the microvasculature contributes to this pathology. The physiological mechanisms regulating homogeneity/heterogeneity of microvascular perfusion are presently unknown. Using established empirical formulations for blood viscosity modeling in vivo (blood vessels) and in vitro (glass tubes), we ...
متن کاملInfluence of endothelial glycocalyx degradation and surfactants on air embolism adhesion.
BACKGROUND Microbubble adherence to endothelial cells is enhanced after damage to the glycocalyx. The authors tested the hypothesis that exogenous surfactants delivered intravascularly have differential effects on the rate of restoration of blood flow after heparinase-induced degradation of the endothelial glycocalyx. METHODS Air microbubbles were injected into the rat cremaster microcirculat...
متن کاملImplications Enzymatic Degradation of the Endothelial Glycocalyx on the Microvascular Hemodynamics and the Arteriolar Red Cell Free Layer of the Rat Cremaster Muscle
The endothelial glycocalyx is a complex network of glycoproteins, proteoglycans, and glycosaminoglycans; it lines the vascular endothelial cells facing the lumen of blood vessels forming the endothelial glycocalyx layer (EGL). This study aims to investigate the microvascular hemodynamics implications of the EGL by quantifying changes in blood flow hydrodynamics post-enzymatic degradation of the...
متن کاملMicrovascular blood flow resistance: role of endothelial surface layer.
Observations of blood flow in microvascular networks have shown that the resistance to blood flow is about twice that expected from studies using narrow glass tubes. The goal of the present study was to test the hypothesis that a macromolecular layer (glycocalyx) lining the endothelial surface contributes to blood flow resistance. Changes in flow resistance in microvascular networks of the rat ...
متن کاملThe glycocalyx is present as soon as blood flow is initiated and is required for normal vascular development.
The glycocalyx, and the thicker endothelial surface layer (ESL), are necessary both for endothelial barrier function and for sensing mechanical forces in the adult. The goal of this study is to use a combination of imaging techniques to establish when the glycocalyx and endothelial surface layer form during embryonic development and to determine the biological significance of the glycocalyx lay...
