[Cell therapy and wound repair].

Cell therapy includes living cell-based therapy and cell-derivative therapy that is based on extracellular vesicles and bioactive molecules. As a research hotspot in recent years, cell therapy is a potential strategy to solve the clinical problem of refractory wound repair. The rapid development of material science and cell biology has opened a new prelude to cell therapy, and at the same time, puts forward a new proposition on how to further optimize and apply cell therapy to wound repair. This article reviewed the cell types used for wound treatment, summarized the application and exploration of cell therapy-based new technologies, sorted out the difficulties in the clinical application of existing cell therapies, and looked into the future development trend of cell therapy for wound repair, in order to promote the development of innovative cell therapy system and further improve the clinical wound treatment effect.
