Abstract
Wound healing is a complex process under precise regulation, including multiple stages such as inflammation, anti-inflammatory, and regeneration. Macrophages play an important regulatory role in the differentiated process of wound healing due to their obvious plasticity. If macrophages fail to express specific functions in a timely manner, it will affect the healing function of tissues and lead to pathological tissue healing. Therefore, it is of great significance to understand the different functions of different types of macrophages and to regulate them specifically in different stages of wound healing to promote the healing and regeneration of wound tissue. In this paper, we illustrate the different functions of macrophages in the wound and their basic mechanisms, according to the basic process of wound healing, and emphasize the strategies of macrophage regulation that may be applied to clinical treatment in the future.
