The main research interest in Lin lab is to understand the etiology and pathogenesis of osteoarthritis, and develop the treating methods accordingly.
1. A human cell derived, three-dimensional (3D), multi-component microphysiological joint chip (microJoint) has been developed, in which osteochondral complexes, synovium and adipose tissues are integrated. This robust in vitro system is being used to study the tissue crosstalk in the onset and progression of osteoarthritis, as well as screen the disease modifying drugs.
2. Aging relevant changes in cartilage/chondrocyte are investigated, with special attention to autophagy. Our final goal is to understand the mechanism underneath the association between aging and osteoarthritis.
3. Stem cell and its biologics-based therapy are also tested for the treatment of musculoskeletal injuries such as focal cartilage defect, which is one of the major reasons leading to the development of osteoarthritis.
