Description of research and/or clinical interests: Dr. Diekman’s lab seeks to combine studies on the basic biology of aging with tools from the field of regenerative medicine to develop novel therapeutic approaches for osteoarthritis (OA). One goal of the lab is to use genome editing of primary human chondrocytes to understand the mechanisms by which particular genetic changes lead to a higher risk of OA. Other projects use rodent models to understand the contribution of “cellular senescence” to age-related OA. Senescence increases with aging and developing strategies to specifically eliminate these dysfunctional cells before they compromise the surrounding cartilage tissue may be one effective strategy for OA therapy.
