What is the cell-based model of coagulation?
Our cell-based model of haemostasis replaces the traditional ‘cascade’ hypothesis, and proposes that coagulation takes place on different cell surfaces in three overlapping steps: initiation, amplification, and propagation.
What is cell-based model?
Cell-based models are mathematical models that represent biological cells as a discrete entities. They are used in the field of computational biology for simulating the biomechanics of multicellular structures such as tissues.
What is cell coagulation?
Coagulation is the process of making blood clot. This is an important and complex process that enables the blood to plug and heal a wound. This is how the body stops any unwanted bleeding. Coagulation involves the action of cells and coagulation (clotting) factors.
What is the cascade model of coagulation?
The cascade model of fibrin formation. This model divides the coagulation system into separate redundant pathways (extrinsic and intrinsic) either of which can result in generation of FXa. The common pathway results in generation of thrombin and subsequent cleavage of fibrinogen to fibrin.
Why is cell model important?
Whole-cell modeling naturally leads to data integration because it attempts to incorporate all possible data pertaining to a particular cell type. A major advantage of whole-cell modeling is that these data are linked mechanistically in the model, through the simulated interaction of biological processes in the cell.
What are the limitations of a cell model?
The major limitation of models is that they are ‘idealizations’ or ‘simplification’ of reality and thus cannot possibly replace reality. A number of assumptions are made during modeling and this causes differences between model and reality.
What causes coagulation?
Blood Clot Formation When you cut or injure yourself, your body stops the bleeding by forming a blood clot. Proteins and particles in your blood, called platelets, stick together to form the blood clot. The process of forming a clot is called coagulation.
How do you explain the clotting cascade?
The plasma clotting cascade consists of a series of reactions involving the activation of zymogens (inert precursors of enzymes) via limited proteolysis. The resulting enzymes are catalytically active serine proteases, yet they have low inherent enzymatic activity as isolated proteins.
