Extracellular vesicles: Roles in oocytes and emerging therapeutic opportunities.

Area of Science:

• Reproductive Biology
• Cellular and Molecular Biology
• Nanotechnology in Medicine

Background:

• Oocyte quality is essential for successful reproduction and is dependent on complex intercellular communication.
• Extracellular vesicles (EVs), nanoparticles involved in molecular transfer, are increasingly recognized for their role in reproductive processes.
• Understanding EV involvement in oocyte biology is critical for advancing female reproductive health diagnostics and therapeutics.

Purpose of the Study:

• To comprehensively review the influence of extracellular vesicles (EVs) on oocyte development and function.
• To discuss the role of EVs in normal female reproductive physiology and under pathological conditions.
• To summarize the therapeutic potential of EVs in enhancing oocyte quality and managing ovarian diseases.

Main Methods:

• Literature review of studies investigating extracellular vesicles (EVs) and their impact on oocytes.
• Analysis of research on EV cargo composition in both physiological and pathological states.
• Synthesis of findings on the application of therapeutic EVs in reproductive medicine.

Main Results:

• Extracellular vesicles (EVs) are integral to intercellular communication, significantly influencing oocyte maturation and quality.
• EV cargo composition changes under pathological conditions, offering insights into ovarian dysfunction.
• Therapeutic administration of EVs demonstrates potential for improving oocyte quality and treating ovarian diseases.

Conclusions:

• Extracellular vesicles (EVs) are key mediators in maintaining oocyte health and reproductive function.
• EVs represent promising biomarkers for diagnosing reproductive disorders and novel therapeutic agents for fertility treatments.
• Further research into EV biology will unlock new strategies for enhancing female reproductive outcomes.
