Sepsis is a fatal disease with high rate of morbidity and mortality, during which acute lung injury the earliest most serious complication. Injury pulmonary microvascular endothelial cells (PMVECs) induced by excessive inflammation plays an important role in sepsis injury. This study meant to explore protective effect mechanism ADSCs exosomes on PMVECs injury.We successfully isolated exosomes, characteristic were confirmed. reduced inflammatory response ROS accumulation cell PMVECs.
