dc.description.abstractCollagen is regarded as one of the most useful biomaterials. The excellent biocompatibility and safety due to its biological characteristics, such as biodegradability and weak antigenecity, made collagen the primary source in biomedical application. Collagen has been widely used in the crosslinked form to extend the durability of collagen. The chemical treatment influences the structural integrity of collagen molecule resulting in the loss of triple helical characteristic. The structural characteristic of collagen is importantly related to its biological function for the interaction with cell. In this study, structural stability of collagen was enhanced thought EGCG treatment, resulting in high resistance against degradation by bacterial collagenase and MMP-1, which is confirmed by collagen zymography. The triple helical structure of EGCG-treated collagen could be maintained at 37degreesC in comparison with collagen, which confirmed by CD spectra analysis, and EGCG-treated collagen showed high free-radical scavenging activity. Also, with fibroblasts culture on EGCG-treated collagen, the structural stability of EGCG-treated collagen provided a favorable support for cell function in cell adhesion and actin filament expression. These observations underscore the need for native, triple helical collagen conformation as a prerequisite for integrin-mediated cell adhesion and functions. According to this experiment, EGCG-treated collagen assumes to provide a practical benefit to resist the degradation by collagenase retaining its structural characteristic, and can be a suitable biomaterial for biomedical application.
