Osteoarthritis (OA) is the most common degenerative disease in the musculoskeletal system. While it can affect any joint, hip, and knee, OA carries an enormous burden of pain and reduced mobility. Despite decades of research, there are currently no clinically effective treatments that can repair damaged cartilage or halt the progression of this disease. However, recent advances in tissue regeneration show that stem cell therapy has the potential to repair damaged cartilage. In addition, ultrasound (US) stimulation has also shown encouraging results in treating OA symptoms. This is because cartilage is a mechanotransductive tissue that responds anabolic to biomechanical stimuli. Therefore, we hypothesize that the combined use of stem cells and US will have a synergistic response in treating OA. This hypothesis will be tested in three specific aims. In the first aim, we compare the chondrogenic differentiation of two different stem cell sources, mesenchymal and adipose, using in vitro 3D culture and US exposure time period. In the second aim, we will implant the optimal US-enhanced chondrogenic cells from Aim 1 in human articular cartilage defects, ex vivo, and compare pulsed to continuous ultrasound. Finally, in the third aim, we will test the optimized US-enhanced chondrogenic hyaluronic hydrogel encapsulated cell in vivo using an OA rat model. These studies will allow us to develop a new ultrasound-induced chondrogenic stem cell therapy that can repair cartilage tissue, regress the OA progression, and reduce osteoarthritic pain significantly.

Public Health Relevance Statement:
Narrative Osteoarthritis is a debilitating disease that affects an enormous number of people. No treatments other than arthroplasty have been developed to stop its progression, reduce pain, and increase range of motion. This proposal seeks to combine the use of hydrogel ,stem cells, and ultrasound therapy to develop a new treatment for osteoarthritis. These approaches have shown some promise alone and their combination will pave the way for a new therapy to reduce OA-associated pain and improve mobility. Importantly, these experiments have been designed to facilitate a rapid proof-of-concept to pave the way for future clinical studies.
