Article Title: The role of small extracellular vesicle-miRNAs in endometriosis
doi: 10.1093/humrep/dead216
Figure Lengend Snippet: Retrograde menstruation is only one part of the endometriosis pathophysiology. (1) Retrograde menstruation brings endometrial cells into the peritoneal cavity. (2) sEVs are produced by all cells (endometrial cells, red blood cells, pMφ, andPMCs) in the peritoneal cavity. (3) sEVs containing miRNAs are taken up by endometrial cells, red blood cells, pMφ, and PMC, causing changes to recipient cells. (4) Uptake of sEVs and internalisation of miRNAs promotes proliferation, migration, and invasion of endometrial cells and of existing ectopic lesions, immunomodulation of macrophages, and potentially EMT changes of PMCs, although none of the studies in this review investigated the impact of sEV-miRNA on PMCs. PF-derived sEVs are likely to originate from a variety of cell types including endometrial cells, red blood cells, immune cells, ectopic lesions, and PMCs. This figure was created with BioRender.com. sEV, small extracellular vesicle; miRNA, microRNA; pMφ, peritoneal macrophage; PMC, peritoneal mesothelial cell; EMT, epithelial-to-mesenchymal transition; PF, peritoneal fluid; sEV-miRNA, small extracellular vesicle-microRNA.
