Catabolic Enzymes and Spontaneous Non-Enzymatic Collagen Cross-Linking - Mechanisms of Articular Cartilage Repair

Description

The presentation features Nicolas Groth Merrild from King's London, discussing his research on tissue engineering and mechanotransduction focusing on the integration of articular cartilage donations with host tissues. The project is divided into two phases: the first identifies biological mechanisms of successful cartilage integration, and the second examines if these mechanisms are mechanoregulated. In the initial phase, Merrild presents data from a juvenile pig model analyzing the integration of osteochondral plugs, emphasizing the functional implications of insufficient cartilage integration. He outlines a series of experimental observations, including the lack of significant changes in collagen synthesis or crosslinkers following injury. Through advanced techniques like Functional Noncanonical Amino Acid Tagging (FUNCAT), the research observes new proteins involved in cartilage integration but highlights ongoing questions about the mechanisms behind this process, bringing attention to the possibility of catabolic enzymes playing a role in cartilage remodeling. The presentation concludes with acknowledgments to his research team and a discussion on the influence of specimen age on integration outcomes.
