My research interest focus on the development and diseases in skeletal and connective tissues such as synovial joint, intervertebral discs, growth plate cartilage and bone. Development of novel therapeutic approaches through understanding the biology of skeletal development and pathogenic mechanism of diseases is also another research focus. One example of my research is the identification of Lgr5+ multipotent joint progenitor cells during embryonic synovial joint development. As these cells can differentiate into almost all kind of cells in an adult joint and could be a true type of progenitor cell for treating joint diseases such as osteoarthritis and ligament rupture. On-going projects include understanding the molecular control of these cells through single-cell transcriptome approach and the potential repair capacities of these progenitors in ligament/tendon and cartilage. Another ongoing project collaborating with Prof. Julian Tanner in our School, is using Oligonucleotide aptamer (also known as “chemical antibodies”) to enhance bone forming cells (osteoblasts) activities and differentiation to enhance bone mass and quality in low bone mass disorders such as osteoporosis and genetic disease Osteogenesis Imperfecta (Brittle bone disease).
