Research Summary:

Dr. Scott’s research program is focused on interrogating the mechanisms that govern tendon and other musculoskeletal tissue development, regeneration and renewal, with the ultimate goal of improving the maintenance and healing capacity of these structures. Recent advances have uncovered critical roles for Mesenchymal Progenitor cells in these processes, a cell population that serves as a musculoskeletal tissue stem cell reserve, but also provides a pro-regenerative microenvironment for other tissue resident stem cells. The fate and function of embryonic, adult and aged Mesenchymal Progenitor cells are examined in health and disease to build a comprehensive understanding of how these cells can be manipulated for therapeutic purposes, including regenerative medicine approaches.
