Current situation and future of tissue engineering applied in wound repair

Tissue engineering technology has been applied in the field of wound repair for decades, and different types of tissue engineering skin substitutes have been developed successively. With the development of 3D bioprinting technology, it provides an ideal method for the development of tissue engineered skin products. At present, although a lot of progress has been made, at the same time, there are also many opportunities for development. This paper reviews and analyses the key elements of tissue engineering in wound repair, including cell therapy, scaffold material and growth factor regulation, and puts forward the significance, difficulties, hotspots and future development strategies and directions of tissue engineering in wound repair. Key words: Tissue engineering; Mesenchymal stem cells; Imaging, three-dimensional; Wound repair; Scaffold material
