Fibrin scaffold

A **fibrin scaffold** is a three-dimensional network formed by the polymerization of fibrin, a protein derived from the cleavage of fibrinogen by thrombin during the clotting cascade. This scaffold functions as a temporary matrix at injury sites, supporting cell adhesion, migration, proliferation, and tissue regeneration. In regenerative medicine, fibrin scaffolds are utilized as biomaterials for tissue engineering due to their biocompatibility and similarity to natural extracellular matrices. The properties of the scaffold—such as porosity, strength, and degradation—can be modified by altering the concentrations of thrombin, fibrinogen, and cross-linking agents (e.g., Factor XIIIa, genipin). Despite their natural suitability, fibrin scaffolds degrade quickly unless chemically stabilized, which can limit their effectiveness in some long-term clinical applications. Fibrin scaffolds are not "targets" in the therapeutic sense; rather, they are products or materials, so "Fibrin scaffold formation" is not a target per established target nomenclature.
