Abstract (original English)

Hepatic ischemia-reperfusion injury (HIRI) severely threatens the success rates of liver surgery and transplantation. Its complex pathological process involves multiple factors such as oxidative stress, inflammatory responses, and ferroptosis, creating an urgent need for new therapeutic strategies. Exosomes derived from mesenchymal stem cells (MSCs) are emerging as a next-generation acellular therapeutic approach. With their outstanding immune-regulatory capabilities, significant reparative functions, and good biocompatibility, they are leading innovations in the field of HIRI treatment. This article provides a systematic comparison of the therapeutic characteristics of MSC-derived exosomes(MSC-EXOs) from four different sources: adipose tissue, bone marrow, umbilical cord, and induced pluripotent stem cells. Although the clinical translation of MSC-EXOs still faces challenges such as variations in isolation methods, large-scale production, and safety assessments, their remarkable therapeutic effects and vast application potential signal the arrival of a new era of precision treatment for HIRI. This review not only provides a comprehensive theoretical foundation to promote the clinical application of MSC-EXOs but also opens up innovative research directions in the field of regenerative medicine.
