Eduardo Abreu, M.D., D.Eng., has been an assistant professor at the UMKC School of Nursing and Health Studies since 2010. The main focus of his research is the musculoskeletal system, more specifically tendons. Reflecting his interdisciplinary background in physics, medicine and biomedical engineering, Dr. Abreu is particularly interested in tenocyte (i.e., the tendon cell) biology, tendon biomechanics, mechanobiology and how tendons communicate with other tissues. Historically, tenocytes have been studied to a lesser extent than other cells of the musculoskeletal system because initially tendons were once seen as mere connectors between bones and muscles. One motivation for the study of tendons is their low healing capacity. As we improve our knowledge about tendons and tenocytes, we will be in a better position to develop improved strategies for the prevention of tendon diseases, faster healing and more efficient tissue engineering approaches. Dr. Abreu is also interested in aging and fall prevention, being an active member of the Consortium for Aging in Community, an interdisciplinary group aimed at fostering aging education, and research at UMKC. Beyond his research work, Dr. Abreu has a deep commitment to education, teaching and serving as co-director of Anatomy and Physiology at SoNHS, one of the largest undergraduate courses at UMKC with over 300 students per semester.
- Calcium cellular metabolism in tenocytes. Using intracellular calcium measurements we have shown the existence of store-operated calcium entry in tenocytes, how calcium oscillations change with aging (figures 1), and how the oscillations can be synchronized among connected tenocytes (figure 2)
- Gene expression changes in tenocytes due to aging
- Role of biomarkers in fall prevention in older adults
