Abstract: BACKGROUND: Current decellularization methods inevitably cause damage to decellularized extracellular matrix scaffolds. To better exploit their advantages as tissue engineering scaffolds, it is particularly important to modify decellularized extracellular matrix scaffolds to improve their performance.
OBJECTIVE: To review the application of decellularized extracellular matrix composite scaffolds in tissue regeneration. 
METHODS: Keywords “decellularized extracellular matrix, tissue engineering, crosslinking, electrospun nanofibers, 3D bioprinting technology, tissue regeneration” were searched on PubMed, WanFang and CNKI databases. The language of the literature was limited to Chinese and English, and the retrieval time was from 2009 to 2022.  A total of more than 142 articles were retrieved, and 79 articles were finally included for review.
RESULTS AND CONCLUSION: The process of removing cells from tissues or organs by chemical, physical and biological methods inevitably leads to ultrastructural damage of decellularized extracellular matrix scaffolds, as well as adverse factors such as poor mechanical properties, and uncontrolled degradation. The composite scaffold can be modified by cross-linking, electrospinning, three-dimensional bioprinting, nanoparticles, methoxy polyethylene glycol, and growth factor, which can optimize the performance of decellularized extracellular matrix scaffold. Among them, three-dimensional bioprinting technology can print more stable and precise composite scaffolds from modified decellularized extracellular matrix bioprinks, showing a great potential for personalized and precise tissue regeneration. However, achieving functional and structural tissue regeneration and clinical transformation still needs to be explored and studied.

Key words: decellularized extracellular matrix, tissue engineering, regeneration, crosslinking, electrospun nanofiber, three-dimensional bioprinting technology, review
