Skin tissue repair pathway

The skin tissue repair pathway (wound healing) is a multi-phase biological process involving hemostasis, inflammation, proliferation, and tissue remodeling. Key cell types include keratinocytes, fibroblasts, endothelial cells, macrophages, and myofibroblasts. Cellular activities span migration, proliferation, differentiation, and extracellular matrix deposition and degradation. Critical molecular drivers include growth factors (PDGF, FGF, EGF, TGF-β), cytokines (IL-24), integrins, metalloproteinases (MMPs), and transcription factors (e.g., HIF1a, STAT3)[1][2][3][4][5][6][7]. The pathway’s efficiency determines scar formation, strength of healed skin, and risk of chronic wounds or fibrosis. Because “Skin tissue repair pathway” refers to a process and not a specific molecule, it is not considered a direct therapeutic target. In drug discovery, individual molecular components of this pathway (such as PDGF receptor, FGFR, EGFR, IL-24, or MMPs) are designated as true molecular targets[3][6]. This entry is therefore marked as incorrect for standardized target nomenclature needs.
