The central focus of our research can be divided programmatically into two parts: 1) the study of the contribution of chondrogenesis and chondrocyte differentiation to the process of fracture repair and 2) the study of the behavior of the articular chondrocyte under normal conditions in healthy joints and during pathologic situations such as joint degeneration. The complex interplay between several key signaling mechanisms, including the TGF-beta, Wnt/beta-catenin and PTH/PTHrP pathways, are important for modulating chondrocyte differentiation and physiology and thus have a critical contribution to play during the fracture healing and joint maintenance/disease. Understanding the specific role of each will lead us to a better understanding of these processes in general and will enable us to design strategies for addressing diverse clinical problems spanning from non-union of fractures to osteoarthritis.
