Placental exosomes as biomarkers for maternal diseases: current advances in isolation, characterization, and detection

Serving as the interface between fetal and maternal circulation, the placenta plays a critical role in fetal growth and development. Placental exosomes are small membrane-bound extracellular vesicles released by the placenta during pregnancy. They contain a variety of biomolecules, including lipids, proteins, and nucleic acids, which can potentially be biomarkers of maternal diseases. An increasing number of studies have demonstrated the utility of placental exosomes for the diagnosis and monitoring of pathological conditions such as pre-eclampsia and gestational diabetes. This suggests that placental exosomes may serve as new biomarkers in liquid biopsy analysis. Griffith University researchers provide an overview of the current understanding of the biological function of placental exosomes and their potential as biomarkers of maternal diseases. Additionally, they highlight current barriers and the way forward for standardization and validation of known techniques for exosome isolation, characterization, and detection. Finally, the researchers discuss microfluidic devices for exosome research.
