Wound microenvironment

The **wound microenvironment** refers to the dynamic local milieu surrounding a wound site. It comprises various cell types (e.g., fibroblasts, immune cells), extracellular matrix components like collagen and elastin, signaling molecules such as cytokines and growth factors, and structural features including blood vessels. This environment orchestrates key processes in wound healing by regulating cellular behaviors—migration, proliferation, differentiation—and mediating immune responses. The composition and properties of the wound microenvironment determine whether healing proceeds normally or results in pathological outcomes like chronic wounds or excessive fibrosis/scarring. Modulating this environment is an emerging strategy for improving tissue regeneration and managing fibrotic diseases; however, it is not itself a discrete therapeutic target but rather a complex system influencing multiple potential targets within it.[1][2][3][8]
