Human Placenta Exosomes: Biogenesis, Isolation, Composition, and Prospects for Use in Diagnostics

Area of Science:

• Obstetrics and Gynecology
• Cell Biology
• Nanotechnology

Background:

• Exosomes are nanovesicles involved in intercellular communication, transferring proteins, nucleic acids, and lipids.
• The placenta releases exosomes into maternal circulation, detectable early in pregnancy and increasing towards term.
• These placental exosomes are crucial for normal placental function and fetal development.

Purpose of the Study:

• To review exosome biogenesis, isolation methods, and biochemical composition.
• To explore the role of placental exosome composition in pregnancy complications.
• To assess the potential of placental exosomes for early diagnosis of pregnancy pathologies.

Main Methods:

• Literature review on exosome biology and function during pregnancy.
• Analysis of studies investigating placental exosome composition.
• Examination of diagnostic potential of exosome analysis in pregnancy.

Main Results:

• Placental exosome concentration and composition change during pregnancy.
• Alterations in exosome biochemical makeup are linked to placental dysfunction and pregnancy complications.
• Exosomes carry bioactive molecules influencing target cells.

Conclusions:

• Placental exosomes are vital indicators of pregnancy status.
• Studying the protein, lipid, and nucleic acid content of placental exosomes offers a promising avenue for early detection of pregnancy disorders.
• Further research into exosome analysis can advance diagnostic tools in prenatal care.
