Abstract

PURPOSE OF REVIEW: To review the role of machine perfusion in advancing the study and clinical application of liver xenotransplantation to liver transplantation. RECENT FINDINGS: Recent multicenter trial has shown the benefits of normothermic machine perfusion (NMP) in the assessment and selection of suitable allografts for liver transplantation, especially marginal liver allografts. Advances in ex-vivo therapeutic intervention with proof-of-concept studies demonstrating successful ex-vivo genetic modification of donor allografts and blockade of gene expression with siRNA. SUMMARY: Xenotransplantation and NMP are two of the most exciting and eagerly anticipated technologies in organ transplantation. Since the emergence of clinical transplantation, clinicians and researchers have attempted to manipulate xenografts for clinical use or to develop devices that could provide physiologic support of donor organs ex vivo. The past decade has seen significant progress in NMP with recent emergence of devices suitable for use in clinical practice. Following discovery of novel gene-editing techniques, xenotransplantation has also developed rapidly with encouraging outcomes in preclinical studies. Xenotransplantation is now currently poised to advance into the clinical realm. NMP can not only assist in the development of other novel technologies by providing a unique environment to safely study organ function and assess organ suitability but may also improve outcomes following hepatic xenotransplantation. In this review, we describe the current use of NMP in xenotransplantation research and also discuss the potential roles for NMP in xenotransplantation research and future clinical practice.
