Research is exploring the role of extracellular vesicles in pregnancy complications, including gestational diabetes, pre-eclampsia, preterm birth, and fetal growth restriction. Studies are investigating various aspects, such as placenta-derived extracellular vesicles and their potential as biomarkers, as well as their involvement in fetal health and development. The relationship between extracellular vesicles and pregnancy complications is being examined from different angles, including their potential as therapeutic targets and their association with clinical features of pre-eclampsia.
