New Technologies and Tissue Repair and Regeneration (1): Stem Cells, Tissue Engineering, and 3D Technology

Since its inception, tissue engineering technology has made significant progress in many fields such as biomedicine, such as the separation of new cell sources and seed cells, the design and synthesis of high biomimetic biomaterial scaffolds, the invention of new drugs and delivery systems, and the development of flux bio-manufacturing technology. Such results have led to the rapid development of some innovative clinical treatment strategies; especially, the repair and regeneration of tissue and organ damage have achieved satisfactory clinical results. At present, tissue engineering and regenerative medicine strategies can be broadly classified into three categories: cell-based therapeutic strategies; stent-therapeutic strategies with acellular scaffolds or seeded cells; and cell-loaded structures or matrix complexes.
