In 1998, BIMA's director and principal investigator, Dr. Jeffrey Toth, and collaborator Dr. John Brekke formulated and published a definition for tissue engineering in the scientific literature: “Tissue engineering is an art and science by which synthetic compounds are manipulated into anatomically and/or functionally specific architectures and, when required, may be integrated with biologically active agents and/or living cells such that resultant properties of the whole are precisely suited to support the specific cell life prescribed for recipient tissues (Brekke and Toth).” Since that time, the OREC's Biomaterials and Histology Laboratory has been actively researching the use of bone graft substitutes and synthetic biomaterials as delivery vehicles for osteoinductive bone morphogenetic proteins. Bima has applied tissue engineering to back or spine musculoskeletal impairment, which has been reported to represent more than half of the musculoskeletal impairments in the United States. In the 18–84 age group, back or spine impairment is the leading cause of activity limitation and results in more lost productivity than any other medical condition. “For outstanding contributions in the field of Biomaterials and Tissue Engineering for research accomplishments and novel clinical applications to bone graft materials and carriers and spinal implant systems,” Dr. Toth was elected to the College of Fellows of the American Institute for Medical and Biological Engineering (AIMBE) in 2010. Located in Washington, D.C., AIMBE recognizes the top 2% of biomedical engineers in the country with the distinction of fellow.
