Extracellular matrix scaffold (for wound healing) (ECM scaffold)

Extracellular matrix scaffolds for wound healing are acellular biomaterials, typically derived from decellularized tissues such as dermis, small intestine submucosa, or amniotic membrane, designed to mimic the natural ECM’s three-dimensional structure and bioactivity. Upon implantation, these scaffolds provide a supportive environment for host cell infiltration, migration, and proliferation, facilitate angiogenesis and granulation tissue formation, and modulate immune responses by promoting anti-inflammatory and pro-regenerative macrophage phenotypes. ECM scaffolds are widely used for chronic wound management, burn repair, and tissue engineering but are not molecular drug targets; rather, they serve as advanced wound dressings and tissue engineering materials.

Provides a structural substrate for cell ingrowth, migration, and attachment. Releases bioactive molecules after degradation. Modulates local immune response (promotes M2 macrophage phenotype, Th2 response). Acts as a reservoir for growth factors and bioactive proteins.
