Dermal fibroblast-mediated extracellular matrix and growth factor secretion

Dermal fibroblasts are the major cellular mediators of wound healing in skin. Upon injury, they become activated by cytokines and growth factors released from immune and stromal cells. They migrate, proliferate, and differentiate (especially into myofibroblasts), secreting extracellular matrix proteins (mainly collagens and fibronectin) and releasing growth factors and cytokines (such as PDGF, TGF-β, VEGF, FGF). These activities promote angiogenesis, re-epithelialization, and matrix deposition, essential for closure and repair of wounds. Overactivation can lead to excessive scarring and fibrosis, while insufficient activity impairs healing. Fibroblasts also interact with immune cells, amplifying inflammatory responses and defending against infection[1][2][4][5][6]. The described "target" is not suitable for listing as a canonical molecule or receptor; instead, it encompasses a class of biological activities and mediators central to tissue repair and skin regeneration. For drug development purposes, it is advisable to specify either the particular extracellular matrix protein, growth factor receptor, or fibroblast subpopulation being targeted[1][2][4][5][6].
