[Research progress of mesenchymal stem cell-derived extracellular vesicles in liver diseases]

Mesenchymal stem cell-derived extracellular vesicles (MSC-EVs) transport and transmit intercellular information and play an essential role in physiological and pathological processes. MSC-EVs, MSC-EVs-microRNA, and genetically modified MSC-EVs are involved in the onset and progression of different liver diseases and play a role in reducing liver cell damage, promoting liver cell regeneration, inhibiting liver fibrosis, regulating liver immunity, alleviating liver oxidative stress, inhibiting liver cancer occurrence, and others. Hence, it will replace MSCs as a research hotspot for cell-free therapy. This article reviews the research progress of MSC-EVs in liver diseases and provides a new basis for cell-free therapy of clinical liver diseases.
