Adipose-derived stem cell exosomes: emerging roles and therapeutic application

Area of Science:

• Regenerative Medicine
• Cell Biology
• Biotechnology

Background:

• Stem cell-derived exosomes are emerging as potent therapeutic agents, potentially replacing traditional Mesenchymal stromal cells (MSCs) therapy.
• Adipose-derived stem cells (ADSCs) are favored for exosome production due to accessibility, low immunogenicity, and high proliferation rates.

Purpose of the Study:

• To review current knowledge on ADSC exosomes.
• To summarize their applications in cell-free therapies for diverse medical conditions.

Main Methods:

• Literature review of ADSC exosome research.
• Analysis of exosome functions including tissue regeneration, immunomodulation, and signaling pathway involvement.

Main Results:

• ADSC exosomes facilitate tissue regeneration via signaling pathways (e.g., Wnt/βcatenin, PI3K/Akt).
• They exhibit immunomodulatory, angiogenic, and cell-promoting properties.
• Applications span diabetes, cardiovascular diseases, wound healing, neurodegeneration, skeletal disorders, respiratory diseases, and skin aging.

Conclusions:

• ADSC exosomes represent a significant advancement in stem cell-free regenerative medicine.
• They offer novel therapeutic insights for managing a wide spectrum of diseases and conditions.
