My research interests are to understand the relationship between aging and osteoarthritis (OA), develop disease modifying drugs for OA treatment, and regenerate articular cartilage through tissue engineering strategy.
- We have pioneered the development a human microphysiological osteochondral tissue to investigate the effect of different risk factors on the initiation and progression of OA. We were recently funded by NIH to engineer a microJoint tissue chip, which is composed with cartilage, bone, fat pad and synovial membrane, to further model joint pathologies and screen candidate treating drugs.
- We are engineering articular cartilage in vitro using mesenchymal stem cells and Induced pluripotent stem cells (iPSCs), by modulating key pathways, such as WNT/β-Catenin.
- We have for the first time applied a visible light based stereolithographic method (VL-PSL,3D printing) to fabricate live cell-laden hydrogel scaffolds with customized geometry and internal architecture for tissue/organ regeneration. We have also developed an innovative visible light-based photo-crosslinking method to quickly fabricate hydrogel scaffolds in situ, with natural or synthesized biomaterials. Currently, we are testing its application for cartilage repair in rabbits and goats.
- We are also working on the characterization of chondrocyte aging and investigating its contribution to OA onset and progress. In particular, we are using RNASeq technology to analyze the difference of transcriptome in young, old and OA cells.
