Research Progress of Skin Tissue Engineering Scaffolds and Their Materials in Wound Repair

In recent years, skin tissue engineering technology has provided new treatment ideas for large-area wound repair. Skin tissue regeneration is mainly based on the use of appropriate tissue scaffolds. There are several types of scaffolds, such as porous, fibrous, microsphere, hydrogel, and acellular scaffolds. Scaffold materials include natural materials and synthetic materials, but either type of single material has its own limitations. At present, most scaffolds are composed of two or more materials to form composites. Therefore an important direction of skin tissue engineering research in the future involves deeply understanding the properties, advantages and disadvantages of the various biomaterials and scaffolds currently used and exploring the construction of biomaterials and scaffolds with better performance. This article reviews the research progress and application value of different tissue scaffolds and scaffold materials in skin tissue engineering, in order to provide reference for clinical application and research and development in the field of wound repair.
