  2. Thrombopoiesis - Wikipedia

    en.wikipedia.org/wiki/Thrombopoiesis

    Thrombopoiesis is the formation of thrombocytes (blood platelets) in the bone marrow. Thrombopoietin is the main regulator of thrombopoiesis. Thrombopoietin affects most aspects of the production of platelets. This includes self-renewal and expansion of hematopoietic stem cells, stimulating the increase of megakaryocyte progenitor cells, and ...

  3. Platelet - Wikipedia

    en.wikipedia.org/wiki/Platelet

    Platelets or thrombocytes (from Ancient Greek θρόμβος (thrómbos) 'clot' and κύτος (kútos) 'cell') are a blood component whose function (along with the coagulation factors) is to react to bleeding from blood vessel injury by clumping, thereby initiating a blood clot. [1] Platelets have no cell nucleus; they are fragments of ...

  4. Thromboregulation - Wikipedia

    en.wikipedia.org/wiki/Thromboregulation

    Thromboregulation is the series of mechanisms in how a primary clot is regulated. These mechanisms include, competitive inhibition or negative feedback. It includes primary hemostasis, which is the process of how blood platelets adhere to the endothelium of an injured blood vessel. [1] [2] Platelet aggregation is fundamental to repair vascular ...

  5. Thrombopoietin - Wikipedia

    en.wikipedia.org/wiki/Thrombopoietin

    Thrombopoietin (THPO) also known as megakaryocyte growth and development factor (MGDF) is a protein that in humans is encoded by the THPO gene. Thrombopoietin is a glycoprotein hormone produced by the liver and kidney which regulates the production of platelets. It stimulates the production and differentiation of megakaryocytes, the bone marrow ...

  6. Coagulation - Wikipedia

    en.wikipedia.org/wiki/Coagulation

    Platelet plug formation: The adhered platelets aggregate and form a temporary plug to stop bleeding. This process is often called "primary hemostasis". [19] Coagulation cascade: It is a series of enzymatic reactions that lead to the formation of a stable blood clot. The endothelial cells release substances like tissue factor, which triggers the ...

  7. Platelet-activating factor - Wikipedia

    en.wikipedia.org/wiki/Platelet-activating_factor

    Platelet-activating factor, also known as PAF, PAF-acether or AGEPC (acetyl-glyceryl-ether-phosphorylcholine), is a potent phospholipid activator and mediator of many leukocyte functions, platelet aggregation and degranulation, inflammation, and anaphylaxis. It is also involved in changes to vascular permeability, the oxidative burst ...

  8. Platelet-derived growth factor - Wikipedia

    en.wikipedia.org/wiki/Platelet-derived_growth_factor

    Platelet-derived growth factor (PDGF) is one among numerous growth factors that regulate cell growth and division.In particular, PDGF plays a significant role in blood vessel formation, the growth of blood vessels from already-existing blood vessel tissue, mitogenesis, i.e. proliferation, of mesenchymal cells such as fibroblasts, osteoblasts, tenocytes, vascular smooth muscle cells and ...

  9. Blood - Wikipedia

    en.wikipedia.org/wiki/Blood

    Blood is composed of blood cells suspended in blood plasma. Plasma, which constitutes 55% of blood fluid, is mostly water (92% by volume), [2] and contains proteins, glucose, mineral ions, and hormones. The blood cells are mainly red blood cells (erythrocytes), white blood cells (leukocytes), and (in mammals) platelets (thrombocytes). [3]
