Objective To investigate the effect of exosomes derived from human placental mesenchymal stem cells (hPMSC-exs) on lipopolysaccharide (LPS)-induced injury of human pulmonary microvascular endothelial cells (HPMECs) and its possible mechanism. Methods hPMSCs were expanded and cultured in vitro and the cell culture supernatant was collected. The hPMSC-exs in the supernatant was separated and purified by ExoQuick exosomes extraction and purification kit. The morphological characteristics of exosomes were observed by transmission electron microscopy, a
