Exosomes Function in Pro- and Anti-Angiogenesis

Area of Science:

• Cell Biology
• Nanotechnology
• Biochemistry

Background:

• Exosomes are nanoscale extracellular vesicles mediating intercellular communication.
• Their biogenesis involves multivesicular bodies (MVBs) fusing with the plasma membrane.
• Exosomes contain diverse molecules influencing cell functions like survival, inflammation, and metastasis.

Purpose of the Study:

• To review the dual roles of exosomes from various cell types in endothelial cell functions.
• To highlight the therapeutic potential of exosomes in angiogenesis.
• To focus on exosome-mediated delivery of angiogenic factors into endothelial cells.

Main Methods:

• Literature review of studies on exosome function and therapeutic applications.
• Analysis of exosome content and their impact on endothelial cell proliferation, migration, and tube formation.
• Examination of exosome-based delivery systems for angiogenic factors.

Main Results:

• Exosomes exhibit context-dependent pro- or anti-angiogenic effects on endothelial cells.
• Different cell-derived exosomes (e.g., from stem cells, tumor cells) display varied impacts on endothelial cells.
• Exosomes can be engineered to deliver therapeutic molecules like proteins, mRNAs, and microRNAs.

Conclusions:

• Exosomes are crucial mediators of cell-to-cell communication with significant roles in angiogenesis.
• Their therapeutic potential lies in their ability to act as natural nanoparticles for targeted delivery.
• Further research into exosome engineering could unlock novel therapeutic strategies for vascular diseases.
