[Research progress on bioartificial liver]

Liver failure is severe liver damage caused by multiple factors, with a very high mortality rate. Artificial liver support systems have become a core strategy for alternative or bridging therapy in the context of the rapid progression of liver failure and high mortality rates with comprehensive internal medicine therapy. Non-bioartificial livers mainly serve as partial substitutes for liver function improvement through procedures such as perfusion, dialysis, and filtration methods. Bioartificial livers provide liver support therapy for patients by integrating detoxification, synthesis, and metabolic functions to simulate hepatic biosynthesis, filling the gap that non-bioartificial livers cannot perform and addressing the difficulties of non-bioartificial livers' heavy reliance on blood products. This paper focuses on reviewing the basic and clinical research progress of bioartificial livers, providing a multidimensional perspective to accelerate their clinical translation.
