Quantifying extracellular vesicles (EVs) in maternal blood offers non-invasive insights into placental health. Variations in EVs signal potential pregnancy complications and adverse outcomes.
Area of Science:
- Obstetrics and Gynecology
- Cell Biology
- Biochemistry
Background:
- Extracellular vesicles (EVs) are cell-released particles containing proteins, lipids, and nucleic acids, influencing recipient cell function.
- Placental and fetal-derived EVs are found in maternal circulation, with levels increasing during pregnancy.
- Altered EV levels are linked to pregnancy complications like gestational diabetes and preeclampsia.
Purpose of the Study:
- To review the clinical utility of quantifying maternal and placental extracellular vesicles (EVs).
- To synthesize current knowledge on EVs as non-invasive biomarkers for placental dysfunction and adverse pregnancy outcomes.
Main Methods:
- Systematic analysis of peer-reviewed journal articles from online databases.
- Focus on studies quantifying pregnancy-related EVs, particularly placental EVs.
Main Results:
- Circulating maternal and fetal EVs can indicate pregnancy complications and adverse outcomes.
- EVs serve as liquid biopsies, providing insights into feto-placental unit status.
- EV detection in maternal blood from the first trimester aids early assessment.
Conclusions:
- Quantification of EVs shows promise as a non-invasive method to detect placental dysfunction.
- Pregnancy-related EVs are valuable biomarkers for predicting adverse pregnancy outcomes.
- Further research is needed to fully understand the role of EVs in pregnancy adaptations and clinical applications.

Exocytosis
Exocytosis is the opposite of endocytosis, which brings molecules inside the cell. Sometimes, the released materials are signaling molecules. For example, neurons typically use exocytosis to release neurotransmitters. Cells also use exocytosis to insert proteins such as ion channels into their cell membranes, secrete proteins for use in the extracellular matrix, or...
