There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Title: The regulatory role of macrophage in the cartilage regeneration after acute injury
Abstract: Macrophages have played an important role in regulating regeneration in various tissues, such as heart, muscle, lung, nerve, bone etc. Despite of their involvement in the pathology of arthritis, how they regulate cartilage regeneration after acute injury remains elusive, the microenvironment of which is different from that of arthritis. To understand immune regulation of cartilage regeneration, we propose the exploration of macrophage function in cartilage regeneration by: (1) developing murine osteochondral defect model with selective joint macrophage depletion to investigate the influence of macrophage depletion on autologous regeneration, (2) developing murine osteochondral defect model with macrophage-based therapy to investigate the influence of exogenous macrophage on cartilage regeneration, (3) investigating cartilage stem cells to explore possible interactions with macrophages. Macrophages can regulate cartilage regeneration in a phenotype- and time- dependent manner.
