  2. Hemostasis - Wikipedia

    en.wikipedia.org/wiki/Hemostasis

    The endothelial cells of intact vessels prevent blood clotting with a heparin-like molecule and thrombomodulin, and prevent platelet aggregation with nitric oxide and prostacyclin. When endothelium of a blood vessel is damaged, the endothelial cells stop secretion of coagulation and aggregation inhibitors and instead secrete von Willebrand ...

  3. Endothelial activation - Wikipedia

    en.wikipedia.org/wiki/Endothelial_activation

    Endothelial activation is a proinflammatory and procoagulant state of the endothelial cells lining the lumen of blood vessels. [1] It is most characterized by an increase in interactions with white blood cells (leukocytes), and it is associated with the early states of atherosclerosis and sepsis , among others. [ 2 ]

  4. Coagulation - Wikipedia

    en.wikipedia.org/wiki/Coagulation

    The division of coagulation in two pathways is arbitrary, originating from laboratory tests in which clotting times were measured either after the clotting was initiated by glass, the intrinsic pathway; or clotting was initiated by thromboplastin (a mix of tissue factor and phospholipids), the extrinsic pathway.

  5. Endothelium - Wikipedia

    en.wikipedia.org/wiki/Endothelium

    The endothelium (pl.: endothelia) is a single layer of squamous endothelial cells that line the interior surface of blood vessels and lymphatic vessels. [1] The endothelium forms an interface between circulating blood or lymph in the lumen and the rest of the vessel wall.

  6. Wound healing - Wikipedia

    en.wikipedia.org/wiki/Wound_healing

    Vascular sprouting: With the breakdown of endothelial basement membrane, detached endothelial cells from pre-existing capillaries and post-capillary venules can divide and migrate chemotactically towards the wound, laying down new vessels in the process. Vascular sprouting can be aided by ambient hypoxia and acidosis in the wound environment ...

  7. Leukocyte extravasation - Wikipedia

    en.wikipedia.org/wiki/Leukocyte_extravasation

    Neutrophils extravasate from blood vessels to the site of tissue injury or infection during the innate immune response.. In immunology, leukocyte extravasation (also commonly known as leukocyte adhesion cascade or diapedesis – the passage of cells through the intact vessel wall) is the movement of leukocytes (white blood cells) out of the circulatory system (extravasation) and towards the ...

  8. Endothelial dysfunction - Wikipedia

    en.wikipedia.org/wiki/Endothelial_dysfunction

    Nitric oxide (NO) suppresses platelet aggregation, inflammation, oxidative stress, vascular smooth muscle cell migration and proliferation, and leukocyte adhesion. [6] A feature of endothelial dysfunction is the inability of arteries and arterioles to dilate fully in response to an appropriate stimulus, such as exogenous nitroglycerine , [ 5 ...

  9. Tissue factor - Wikipedia

    en.wikipedia.org/wiki/Tissue_factor

    The F3 gene encodes tissue factor also known as coagulation factor III, which is a cell surface glycoprotein. This factor enables cells to initiate the blood coagulation cascades, and it functions as the high-affinity receptor for the coagulation factor VII. The resulting complex provides a catalytic event that is responsible for initiation of ...
