In the Laboratory for Musculoskeletal Crosstalk, we leverage interdisciplinary approaches in bioengineering, endocrinology, and physiology to determine molecular mechanisms of tissue crosstalk in osteoarthritis. Our work aims to delineate fat-cartilage signals that contribute to osteoarthritis susceptibility and pain to generate a new class of regenerative medicine-based therapies. We use in vitro and in vivo approaches, induced pluripotent stem cells, CRISPR-Cas9 genome engineering, mouse models, human tissues, and state-of-the-art multi-omic spatial approaches. As pathological fat signaling may play a role in many disease processes, we work to define the mechanisms and create therapies that have implications to aging, obesity, diabetes and other chronic diseases.
