Liver transplantation is currently the only effective treatment for patients with end-stage liver disease; however, donor liver scarcity is a notable concern. As a result, extensive endeavors have been made to diversify the source of donor livers. For example, the use of a decellularized scaffold in liver engineering has gained considerable attention in recent years. The decellularized scaffold preserves the original orchestral structure and bioactive chemicals of the liver, and has the potential to create a liver that is fit for transplantation after recellularization. The structure of the liver and hepatic extracellular matrix, decellularization, recellularization, and recent developments are discussed in this review. Additionally, the criteria for assessment and major obstacles in using a decellularized scaffold are covered in detail.
肝移植是目前治疗终末期肝病患者的唯一有效方法;然而,供肝短缺是一个值得关注的问题。因此,人们已做出广泛努力以使供肝来源多样化。例如,近年来在肝脏工程中使用去细胞支架受到了相当大的关注。去细胞支架保留了肝脏的原始组织结构和生物活性化学物质,并且有可能在重新细胞化后制造出适合移植的肝脏。本文综述了肝脏和肝细胞外基质的结构、去细胞化、重新细胞化以及最新进展。此外,还详细介绍了使用去细胞支架的评估标准和主要障碍。
