Potentials of Polyphenols in Bone-Implant Devices

Knowledge of bioactive plant-derived polyphenols is growing to such an extent that science interest is looking at development of different applications in regenerative medicine through new and state-of-the-art tissue engineering technologies. Due to their well-established and demonstrated antioxidant and anti-inflammatory beneficial properties, polyphenols have been extensively investigated to the extent that they provide benefits to different pathological conditions, including cardiovascular and bone diseases, neurodegenerative disorders, and cancer. By taking into account the main molecular pathways of polyphenols’ action, we want to focus this chapter on applications of polyphenols in bone-implant devices. In particular, results of polyphenols’ effects on bone cells and tissues following local delivery from innovative biomaterials will be discussed, together with preliminary in vivo tests. Purpose of the dissertation is to provide the reader new insights into knowledge of polyphenols not only regarding the different molecular mechanisms involved in their action but also the biological responses deriving from local applications
