Investigation of the underlying mechanisms of bone regeneration using in vivo mouse models


We focus on three major areas of bone healing: (1) the underlying cell and molecular regulatory mechanisms involved in skeletal development and fracture repair, (2) the role of the mechanical environment during fracture repair, and (3) stem cell-based tissue engineering strategies to enhance bone regeneration. Assays performed in the lab include, but are not limited to in vivo fracture healing models in mouse, rat and rabbit, bone histomorphometry, genetically modified mouse models, in situ hybridization, microCT analysis, and routine cell and molecular biology techniques. We were recently funded to examine the embryonic origin of skeletal stem cells, and how the embryonic origin affects their regenerative potential. Other studies investigate the effect of Wnt3a, a pro-osteogenic protein, on aged bone grafts. This line of work integrates basic science research in the field of bone regeneration with a relatively new target indication: enhancing the osteogenic potential of aged bone autograft.
