Various types of biomaterials have been developed and utilized for the repair of damaged tissue and organs and the biocompatibility of these materials is of major concern. Tissue engineered scaffolds should provide adequate mechanical strength during the initial healing state, and the highly porous structure should provide an ideal environment for the migration and proliferation of cells; additionally, during surgical operations, the scaffolds should be able to be handled and sutured. Therefore, many researchers have designed reinforced scaffolds so as to address these issues. The structures described can be applied to the development of artificial ligaments, tendons, skin, bones, cartilage, and trachea.
