Key Issues and Novel Strategies of Stem Cell Intervention and Decellularized Scaffold Liver Tissue Engineer for End-Stage Liver Disease

Abstract

: End-stage liver disease (ESLD) is ultimation of all kinds of chronic liver diseases. It is highly morbidity and mortality disease and currently no effective treatment is available. Liver transplantation (LTx) is the only way for the treatment. However, the organ source limitation interferes with clinical application of LTx. For the goal of crossing liver source shortage barrier, researches attempt to explore techniques or methods like stem cells and tissue engineering, and recent years sounds developed rapidly and bright prospects, for example, artificial liver, tissue-engineered liver and xenotransplantation etc., in particular adult stem cells like bone marrow-derived mesenchymal stem cells ( BM MSCs) and decellularized liver scaffold for large scale liver tissue engineer seems more eye-catching, and such decellularization / recellularization technology used has become the first strategy to build complex organs. We have previously discussed some points in the about optimizing bioscaffold materials that probably will be benificial for tissue engineer. In the present review, we would like to discuss some new developments based on research status and provide a little new thoughts, hopefully those can help people in this field in order to treat ESLD in the near future.
