Placenta is endocrine organ that regulate biological function of several maternal tissues and fetal organs by specific mechanisms of cell-to-cell cooperation, which is realized via exosomes' secretion. Exosomes delivery some molecules, i.e., active proteins, pro-coagulants, growth factors, lipids, enzymes, micro-RNAs to target cells and induce autocrine / paracrine effects on vasculature and trophoblast. Interestingly, circulating number of exosomes derived from placenta cells in healthy

Moreover, pregnancies at risk of preeclampsia exhibit extremely increased levels of total exosomes and placental cell-derived-exosomes in blood when compared with woman at risk free of preeclampsia. Taking into consideration this fact, measure of circulating number of placental cell-derived-exosomes could be an individual probe for personification of a risk of life-threatening event across pregnancy. The short communication is depicted the role of placental cell-derived-exosomes as biomarker of preeclampsia in asymptomatic pregnancies.
