Abstract:Sepsis is an important problem faced by critically ill patients in critical care for a long time. It is one of the main causes threatening life of critically ill patients, and the prevalence rate is increasing. However, there is no effective treatment. In recent years, mesenchymal stem cells (MSCs) have been used in preclinical studies for the treatment of sepsis due to their properties, including immunomodulatory, antibacterial, regulating organ failure, anti-apoptosis, and anti-inflammasome which are more related to the pathogenesis of sepsis. This article describes the relevant knowledge of MSCs in the treatment of sepsis and the current research on the treatment of sepsis in vitro and in vivo in order to explore new ideas and future efforts of MSCs in the treatment of sepsis.
