Dr. Demer helped pioneer the field of research in cardiovascular calcification, studying its mechanisms at the level of cellular, molecular and biomechanical regulation. Her research group overcame dogma in demonstrating that bone and marrow form in human arteries, often in association with atherosclerosis, and that the process is both regulated and related to embryonic bone formation. They developed the first tissue culture model of vascular calcification, isolated and cloned the cells responsible for producing calcium mineral, and identified the regulatory molecules controlling the re-differentiation of vascular cells into osteooblastic cells. Her group is currently addressing the conundrum that coronary calcification is associated with increased risk of cardiovascular events, but it also progresses most rapidly in patients using statin drugs (which are associated with reduced risk), and it is more prevalent in elite endurance athletes.
