Advanced Wound Care for Chronic Ulcer Management
Summary
Chronic ulcers, including diabetic foot and venous leg ulcers, represent a pervasive global health challenge marked by prolonged inflammation, impaired tissue regeneration and high risk of infection. Advanced wound care aims to shift non-healing wounds towards resolution by integrating novel biomaterials, growth factors and engineered scaffolds with established modalities such as moist dressings and negative-pressure therapy. Cutting-edge approaches employ decellularised extracellular matrix grafts, living cell-based allografts and growth-factor-loaded hydrogels to recreate a reparative microenvironment. These interventions stimulate angiogenesis, modulate the inflammatory response and promote granulation tissue formation. Concurrently, innovations in telemedicine and point-of-care diagnostics enable personalised treatment regimens and timely debridement. Economic analyses underscore both the cost burden of chronic wounds and the potential savings associated with reduced healing time. The convergence of tissue engineering, biomaterials science and digital health is redefining standards of care and delivering more predictable outcomes for patients worldwide.

Advanced Wound Care for Chronic Ulcer Management publication trend
The graph below shows the total number of articles in advanced wound care for chronic ulcer management across all publications each year (not limited to Nature Index journals).
Technical terms
Extracellular matrix (ECM): A network of proteins and polysaccharides providing structural support and biochemical cues essential for tissue repair.
Angiogenesis: Formation of new blood vessels from existing vasculature, crucial for oxygenation and nutrient delivery in healing tissue.
Decellularisation: Process of removing cellular components from donor tissue to yield an acellular scaffold retaining native ECM architecture.
Bioengineered scaffold: Three-dimensional construct designed to support cell attachment, proliferation and differentiation during regeneration.
Negative-pressure wound therapy: Application of subatmospheric pressure to a wound bed to remove exudate, reduce oedema and stimulate granulation tissue.
