(CIT): The topics to be covered will encompass the use of components of the body, such as genes, proteins, and cells, to either foster tissue regeneration and remodeling in vivo for the purpose of repairing, replacing, maintaining, or enhancing organ function, or to engineer functional tissues in vitro for implantation in vivo as a biological substitute for damaged or diseased tissues and organs. The NIH BECON symposium seeks to achieve a better understanding of this exciting field, communicate new developments, and explore future research possibilities to ensure that the NIH is poised to facilitate biomedical research incorporating reparative medicine concepts and tools.
