Placental exosomes viewed from an ‘omics’ perspective: implications for gestational diabetes biomarkers identification

Abstract

Exosomes are defined as extracellular vesicles that are released from cells upon fusion of an intermediate endocytic compartment – the multivesicular body – with the plasma membrane. Recently, placenta-derived exosomes have gained special attention, since they play a crucial role in the communication between the mother and fetus. It is known that the concentration of placenta-derived exosomes in the maternal bloodstream is higher in patients with preeclampsia or gestational diabetes mellitus. However, their composition in terms of the content of proteins, nucleic acids or lipids is uncertain. In this work, we reviewed the recent advances in placental exosomes characterization through omics-based methods, and their potential to predict gestational diabetes mellitus.
