Platelet-rich fibrin is an autologous blood concentrate investigated as a biomaterial within the field of regenerative medicine. This academic concept encompasses the study of its preparation methods and biological composition, characterized by a dense fibrin matrix embedding concentrated platelets, leukocytes, and growth factors. Research focuses on elucidating the mechanisms by which it promotes tissue healing and regeneration through the sustained release of signaling molecules, exploring its diverse clinical applications, and assessing its significance as a versatile and biologically potent therapeutic strategy.
