The vascular endothelium, a monolayer of endothelial cells (EC), constitutes the inner cellular lining of arteries, veins and capillaries and therefore is in direct contact with the components and cells of blood.

Endothelial cells of developing arteries and veins express different cell-surface proteins, which may control the way in which they link up to create a capillary bed. A homeostatic mechanism ensures that blood vessels permeate every region of the body.

Oct 5, 2022 · Artery differentiation is coupled to cell cycle arrest, and new arteries expand during development by recruiting endothelial cells from capillaries and veins.

Vascular endothelial cells (ECs) form the inner lining of all blood vessels from the largest artery and veins, viz., the aorta and venae cavae, respectively, to the capillaries that connect the arterial and venous systems.

Endothelial cells in arteries and veins appear more continuous and thicker than those in capillaries which are fenestrated and thinner to allow for exchange of metabolites and gases . In addition, endothelial cells can display heterogeneous responses to stimulation in different vascular beds, and even in different sections of the same vascular ...

Sep 5, 2024 · It discusses the diverse functions of endothelial cells throughout the vasculature’s life cycle and advocates for understanding the vasculature as a dynamic and interactive organ system, with implications for preventive regenerative health interventions.

Jan 28, 2025 · During development, endothelial cells (ECs) undergo an extraordinary specialization by which generic capillary microcirculatory networks spanning from arteries to veins transform into patterned ...

Sep 7, 2019 · The vascular endothelium, a monolayer of endothelial cells (EC), constitutes the inner cellular lining of arteries, veins and capillaries and therefore is in direct contact with the components and cells of blood.

Oct 23, 2019 · Endothelial cells exposed to inflammatory stimuli from the circulation or the microenvironment exhibit impaired vascular tone, increased permeability, elevated procoagulant activity, and dysregulated vascular formation, collectively contributing to the development of vascular diseases.

May 31, 2012 · For more than a decade, a prevailing hypothesis in research related to arterial disease has been that circulating endothelial progenitor cells (EPCs) provide protection by their innate ability to replace dysfunctional or damaged endothelium.
