8. Principal Investigator: MTF Investigator Grant: Local Dexamethasone Delivery for Osteochondral Grafting, TC: $300,000, 2/1/15-1/31/18.  This application aims to improve osteochondral repair of full thickness cartilage defects by intra-articular delivery of the steroid dexamethasone from engineered osteochondral plugs placed in the graft donor sites as part of an autologous osteochondral transfer procedure.  The team includes collaborators from Columbia (Ateshian),  the University of Pittsburgh (Marra) and University of Missouri (Cook, Kuroki).  (paperwork pending)

Research Summary

Dr.Hung has been pursuing in-depth multidisciplinary collaborations with faculties and students from the Departments of Biological Sciences, Mechanical Engineering, Chemical Engineering and Orthopaedic Surgery using with state-of-the-art biological and engineering tools to perform research aimed atthe study of physical effects (e.g., cell deformation, fluid flow effects,hydrostatic pressure) on cells and tissues, and the incorporation of these forces in strategies to develop functional tissue substitutes of clinical relevance. An understanding of the effects of physical forces on cells isimportant in the development of effective tissue replacements which mimic orrestore normal tissue structure-function in orthopaedic and other load-bearing tissues of the body. Such studies are aim at alleviating the most prevalent and chronic problems afflicting the musculoskeletal system such as arthritis, and problems related to sports and occupational injuries.
