Dr. Louis Terracio is Associate Dean for Research, Professor in the Department of Basic Science and Craniofacial Biology and Professor of Pediatrics at the School of Medicine. Dr. Terracio's research interests center on Cell-Extracellular Matrix (ECM) interaction during development and the application of Cell-ECM interactions to tissue engineering and regenerative medicine. In particular his lab investigates the role of integrins in the formation of normal muscle. An intact ECM-Integrin-Cytoskeletal complex appears to be essential for normal muscle orientation and pattern formation. His lab has demonstrated that thin aligned gels of collagen result in cultured myocytes taking on an elongated rod shape similar to in vivo. This system allowed his lab to investigate the effects of stretch on myocytes in either the long axis of the cell or across the short axis, where the ECM-Integrin-Cytoskeletal complex is most abundant. Data from this model coupled with data from a low shear culture environment on the Space Shuttle has led Dr. Terracio to focus his current research on tissue engineering muscle.

Dr. Terracio's lab is one of the first to tissue engineer a skeletal muscle construct that has structure and function similar to intact muscle. The muscle constructs tetanize and have length tension curves that are nearly identical to in vivo skeletal muscle. The magnitude of the force generated is small due to the small cross sectional area of the constructs. However, his lab has transplanted the constructs into rats with promising results. His lab currently is isolating stem cells (satellite cells) from muscle biopsies from pigs to determine the feasibility of using this system to replace lost skeletal muscle in humans.
