Future in regenerative surgical discipline: construction engineered liver with optimized strategy of decellularized and recellularized technology

End-stage liver disease (ESLD) is a serious threat to human health, and liver transplantation is the only effective treatment. However, most of the patients died in the process of waiting for transplantation due to the shortage of liver source. With the rapid development of biological tissue enginee-ring technology, researchers have established the strategy of ‘decellularized and recellularized technology’, which has deve-loped into the first choice for construction of important organs such as the liver and opened up new ideas for the treatment of ESLD. At present, scientists are working on the optimization of this technology, in order to construction a functional ‘new liver’for transplantation. The authors review the feasibility and challenges of the application of this technology and its optimization stra-tegy in the field of regenerative surgery.
