Summary: | This review focuses on fibrin, starting from biological mechanisms (its production from fibrinogen and its enzymatic degradation), through its use as a medical device and as a biomaterial, and finally discussing the techniques used to add biological functions and/or improve its mechanical performance through its molecular engineering. Fibrin is a material of biological (human, and even patient's own) origin, injectable, adhesive, and remodellable by cells; further, it is nature's most common choice for an in situ forming, provisional matrix. Its widespread use in the clinic and in research is therefore completely unsurprising. There are, however, areas where its biomedical performance can be improved, namely achieving a better control over mechanical properties (and possibly higher modulus), slowing down degradation or incorporating cell‐instructive functions (e.g., controlled delivery of growth factors). The authors here specifically review the efforts made in the last 20 years to achieve these aims via biomimetic reactions or self‐assembly, as much via formation of hybrid materials.
Fibrin is the “glue” responsible for the formation of blood clots, but also a provisional extracellular matrix component that instructs tissue remodeling, and an injectable medical device. Starting from the biophysical basics of fibrin formation and degradation, here its current clinical uses and the (macro)molecular level strategies adopted to engineer it are reviewed. |
