Regeneration of Bone and Cartilage. Stem Cells.
Dr. Reddi was the first recipient of the Marshall Urist Award for Excellence in Tissue Regeneration Research. Established in 1996 by the Orthopaedic Research Society, the award honors a society member whose research excellence in tissue regeneration mirrors the accomplishments of Marshall Urist, a pioneer in the field of tissue engineering. Dr. Reddi's research played an indispensable role in the identification of bone morphogenetic proteins (BMPs) that cause new bone to grow. His research interests are the regeneration and repair of bone, cartilage and meniscus. Current projects are bone morphogenetic proteins and cartilage repair. He also has research interests in the cellular and molecular basis of cartilage repair and osteoarthritis; the cellular and developmental biology of bone and osteoporosis; the tissue engineering of bone and cartilage based on biomaterials and biotechnology; the role of extracellular matrix and growth factors in cell differentiation and morphogenesis of bone and cartilage; and hormonal regulation of cartilage, bone and bone marrow development.
