Exosomes in Osteoarthritis: Breakthrough Innovations and Advanced Tissue Engineering for Cartilage Regeneration Since...

Area of Science:

• Extracellular Vesicle Biology
• Regenerative Medicine
• Osteoarthritis Pathophysiology

Background:

• Osteoarthritis (OA) is a degenerative joint disease with no current cartilage-repairing drugs.
• Exosomes, small extracellular vesicles, are increasingly implicated in OA pathogenesis.
• Advanced OA often necessitates joint replacement surgery.

Purpose of the Study:

• To review exosome biology, isolation methods, and their role in OA.
• To explore the clinical therapeutic potential of exosomes for OA.
• To provide insights into exosome-based regenerative strategies.

Main Methods:

• Systematic literature review of studies published since 2020.
• Focus on exosomes in osteoarthritis (OA) research.
• Analysis of biological properties, isolation, pathological roles, and therapeutic applications.

Main Results:

• Exosomes from various sources (synovial fluid, MSCs) modulate OA processes like inflammation and matrix degradation.
• Cell-derived exosomes demonstrate therapeutic promise for cartilage damage.
• Novel delivery methods may enhance exosome-based OA therapies.

Conclusions:

• Exosomes have dual roles in OA pathogenesis and treatment.
• Exosome-based therapies offer a promising cell-free approach for OA.
• Challenges in standardization and delivery require further investigation for personalized medicine.
