Wound bed microenvironment modulation

Wound bed microenvironment modulation is a therapeutic approach that aims to actively change the biological, chemical, and physical environment within a wound bed—most commonly by delivering hydrogels, bioactive dressings, cytokines, and growth factors, or by controlling moisture—to accelerate healing, control inflammation, and promote tissue regeneration. This strategy does not refer to a discrete molecular entity but encompasses diverse interventions including engineered biomaterials, protein/cytokine therapies, and advanced wound dressings designed to create favorable conditions for cell survival, migration, angiogenesis, and matrix formation. Modulation mechanisms often leverage selective dampening of pro-inflammatory signals (M1/M2 macrophage polarization, TNF-α reduction), stimulation of re-epithelialization, and guidance of the immune and cellular landscape to promote healing, particularly in chronic or poorly healing wounds.
