Abstract: BACKGROUND: Mesenchymal stem cells are used in flap ischemia-reperfusion injury due to their antioxidant and inflammatory inhibition, and angiogenesis induction.
OBJECTIVE: To review the mechanism and latest treatment progress of mesenchymal stem cells in the treatment of flap ischemia-reperfusion injury, and to provide a basis for further theoretical research and clinical rational application.
METHODS: We searched the relevant articles indexed in CNKI, WanFang and PubMed databases. Chinese and English search terms were “mesenchymal stem cells; flap ischemia reperfusion injury; conditioned medium; exosomes; oxidative stress; inflammatory reactions; angiogenesis”. Relevant literature since 2010 was searched, and 74 articles were finally included after excluding the literature that had little to do with the topic of the article, poor quality and outdated content.  
RESULTS AND CONCLUSION: (1) Mesenchymal stem cells play significant roles in antioxidation, inhibition of inflammation and induction of angiogenesis and have great potential in the treatment of flap ischemia-reperfusion injury. (2) However, the defects of mesenchymal stem cells themselves and the decline of therapeutic effect in recent years have put the development and application of mesenchymal stem cells into a bottleneck period, and the research on the plasticity of mesenchymal stem cells conditioned medium and its exosomes and mesenchymal stem cells came into being, and the therapeutic effect was significantly better than the use of mesenchymal stem cells alone. (3) Therefore, a more comprehensive understanding of the mechanism of action and the latest treatment progress of mesenchymal stem cells in the treatment of flap ischemia-reperfusion injury is of great significance for the research of mesenchymal stem cells and the treatment of flap ischemia-reperfusion injury. 

Key words: mesenchymal stem cell, flap ischemia-reperfusion injury, conditioned medium, exosome, oxidative stress, inflammatory reaction, angiogenesis
