Background:

• Tissue repair involves complex immune cell interactions, with M2 macrophages playing a vital role.
• M2 macrophage-derived exosomes (M2-Exos) mediate intercellular communication via microRNAs (miRNAs), influencing tissue regeneration.
• Understanding these mechanisms is crucial for developing regenerative therapies.

Purpose of the Study:

• To review exosome biogenesis, miRNA synthesis and function, and exosome extraction methods.
• To summarize the diverse functions and mechanisms of M2-Exos miRNAs in tissue repair across various biological systems.
• To explore the potential applications of M2-Exos in disease prevention, diagnosis, and clinical practice.

Main Methods:

• Literature review of exosome biology and miRNA functions.
• Analysis of studies on M2-Exos in different tissue repair models.
• Synthesis of current research on therapeutic applications and challenges.

Main Results:

• M2-Exos deliver specific miRNAs that modulate cellular processes essential for tissue repair.
• These exosomes have demonstrated efficacy in promoting healing in various injury models.
• Identified key miRNAs and their targets involved in M2-Exo-mediated repair.

Conclusions:

• M2-Exos represent a promising cell-free therapeutic strategy for tissue injury repair.
• Further research is needed to optimize exosome extraction and clinical application efficiency and safety.
• The therapeutic potential of M2-Exos in regenerative medicine is significant but requires further validation.
