Skin Grafting Techniques in Wound Healing
Summary
Skin grafting remains a cornerstone of reconstructive surgery for burns, chronic ulcers and extensive wounds. Techniques range from conventional split-thickness and full-thickness autografts to advanced cell-based and engineered constructs. Split-thickness grafts, harvested with dermatomes, offer rapid re-epithelialisation but can leave a mosaic pattern and carry donor-site morbidity. Full-thickness grafts deliver superior cosmetic results yet are limited by donor availability and risk of graft failure. To overcome these challenges, recent innovations include minced autologous cell suspensions, micro-column harvesting, and auxetic scaffold designs that amplify coverage and foster vascular ingrowth. Integration of synthetic dermal substitutes, extracellular matrix coatings and growth-factor delivery systems has improved graft take, reduced scarring and accelerated functional recovery. Collectively, these advances are establishing new paradigms in personalised wound care with the prospect of reducing donor-site burden, enhancing cosmetic outcomes and extending treatment to patients with limited skin reserves.

Skin Grafting Techniques in Wound Healing publication trend
The graph below shows the total number of articles in skin grafting techniques in wound healing across all publications each year (not limited to Nature Index journals).
Technical terms
Autologous: Tissue or cells derived from the same individual, eliminating immune rejection risk.
Split-thickness skin graft (STSG): A graft comprising epidermis and part of the dermis, offering rapid wound coverage but potential mosaic patterning.
Dermal substitute: A scaffold material, often collagen-based, applied beneath or over grafts to promote neovascularisation and dermal regeneration.
Auxetic structure: A design that expands laterally under tension, enhancing graft coverage without increasing donor-site size.
Epidermal stem cell (EpSC): A keratinocyte sub-population with high regenerative capacity, crucial for long-term graft stability and wound re-epithelialisation.

About these summaries
This Nature Research Intelligence Topic summary is created with the cited references and a large language model. We take care to ground generated text with facts, and have systems in place to gain human feedback on the overall quality of the process in line with our AI principles. We strive to create accurate and useful summaries for people unfamiliar with the research topic and that supports this goal. These pages are a beta release and will be updated as we learn how best to help people gain value from a research topic summary.
