4. Biology and argumentation of fracture, cartilage and tendon repair.
Our team has long-term research interests in fracture repair biology and argumentation. We have successfully developed mouse and rat fracture repair model and identified the factors that affect the fracture repair outcome such as mechanical factors, inflammation, growth factors as well as genes and microRNAs. We have also tested novel methods for promoting fracture healing such as using stem cells, growth factors, Sclerostin antibody etc. We also developed animal models for cartilage and tendon repair; and we have recently reported novel involvement of non-coding long chain RNAs in tendon stem cell differentiation and cartilage repair. We have found that Smad7 plays an important role in bone development and osteoporosis. We will continue to explore the novel biological mechanisms and applications for musculoskeletal tissue repair and regeneration.
