Plant-Derived Exosomes in Skin Wound Repair: Biological Properties, Extraction, Characterization, and Therapeutic...

Area of Science:

• Biomaterials Science
• Regenerative Medicine
• Nanotechnology

Background:

• Conventional skin wound repair therapies exhibit limited efficacy and significant side effects.
• Novel bioactive therapeutic strategies are urgently needed for effective skin regeneration.
• Plant-derived exosomes (PDEs) are emerging as a promising nanovesicle formulation for wound treatment.

Purpose of the Study:

• To review the biological properties, extraction, and characterization of plant-derived exosomes (PDEs).
• To elucidate the biological functions and mechanisms of PDEs in skin wound repair.
• To summarize the applications, future potential, and challenges of PDEs in precise wound repair therapy.

Main Methods:

• Literature review of existing studies on plant-derived exosomes in skin wound repair.
• Analysis of mechanisms including anti-inflammatory effects, angiogenesis promotion, and cell proliferation/migration.
• Exploration of extraction and characterization techniques for PDEs.

Main Results:

• Plant-derived exosomes (PDEs) possess low immunogenicity, high biocompatibility, and trans-barrier delivery capabilities.
• PDEs accelerate skin tissue repair via multi-dimensional regulation of inflammatory responses, angiogenesis, and cell activities.
• Current research on PDEs for wound repair mechanisms is limited, underscoring their novelty.

Conclusions:

• Plant-derived exosomes (PDEs) demonstrate significant potential as a novel therapeutic strategy for skin wound repair.
• Further exploration of PDEs' biological functions and mechanisms is crucial for developing precise wound repair therapies.
• PDEs offer a promising avenue for advanced regenerative medicine, overcoming limitations of current treatments.
