Research progress of exosomal miRNA in skin wound healing and regeneration / 中国临床药理学与治疗学

ABSTRACT

Skin is the largest organ of the human body, and maintaining the integrity of the skin is very important to maintain the normal function of the body. Repair and regeneration after skin trauma is a complex dynamic process, which involves biological processes such as cell proliferation and migration, extracellular matrix synthesis and deposition, angiogenesis and remodeling. Recently, exocrine miRNA is increasingly considered as a potential therapy for the treatment of skin trauma. Exosomes, as intercellular messengers, can affect the function of target cells through fusion, endocytosis and receptor-ligand interaction. MiRNA, the main component of exosomes, plays an important role in all stages of wound repair. Therefore, understanding the specific role of exocrine miRNA in skin wound repair and regeneration may provide a powerful basis for the development of new treatments for skin trauma in the future. In this review, we summarized the role of exocrine miRNA in the three stages of inflammation, proliferation and remodeling of skin wound repair and regeneration, and expounded its mechanism. In addition, we also discussed the current limitations and future prospects of the study of exocrine miRNA in skin wound repair and regeneration, in order to provide ideas for follow-up research.
