The role of extracellular vesicles from placenta and endometrium in pregnancy: Insights from tumor biology

Area of Science:

• * Cell biology
• * Reproductive biology
• * Oncology

Background:

• * Extracellular vesicles (EVs) are crucial for intercellular communication, mediating physiological and pathological processes.
• * Tumor-derived EVs significantly influence the tumor microenvironment (TME), impacting tumor generation, progression, and metastasis.
• * Successful pregnancy, like tumor development, relies on complex intercellular communication.

Purpose of the Study:

• * To review the impact of tumor-derived EVs on tumor cells and the TME.
• * To draw parallels between tumor biology and pregnancy, focusing on shared EV-mediated processes.
• * To highlight the role of EVs in reproductive biology, including implantation and maternal-fetal interactions.

Main Methods:

• * Literature review and synthesis of existing research on extracellular vesicles.
• * Comparative analysis of EV functions in tumor biology and pregnancy.
• * Discussion of challenges and future directions in EVs research.

Main Results:

• * Tumor-derived EVs modulate the TME and influence tumor progression.
• * Shared biological processes like immune response, invasion, migration, and angiogenesis are mediated by EVs in both tumors and pregnancy.
• * Placenta- and endometrium-derived EVs play vital roles in establishing and maintaining pregnancy.

Conclusions:

• * EVs are critical mediators in both tumor progression and successful pregnancy.
• * Understanding EV communication in reproduction can provide insights into both normal physiology and disease states.
• * Standardization of EV isolation and analysis methods is crucial for diagnostic and therapeutic applications in reproductive health and oncology.
