Autologous Skin Cell Suspension Grafting: A Fundamentally Different Approach to Skin Restoration
Summary: This editorial in Wounds journal addresses autologous skin cell suspension (ASCS) technology as a meaningfully distinct advance beyond conventional split-thickness skin grafting (STSG). Traditional STSG — long the gold standard for coverage of burns and complex wounds — requires large donor sites, creates significant donor site morbidity, and is associated with delayed healing, hypertrophic scarring, and prolonged hospital stays. ASCS, prepared at the point of care using devices such as the RECELL® System, produces a spray suspension of keratinocytes, fibroblasts, and melanocytes from a small biopsy specimen, achieving an 80:1 expansion ratio that dramatically reduces donor skin requirements. Clinical evidence supports its use in partial- and full-thickness burns, nonthermal traumatic wounds, necrotizing infections, and chronic nonhealing wounds. The editorial contextualizes the growing body of evidence — including RCTs and real-world cohort studies — demonstrating ASCS achieves wound closure rates comparable or superior to STSG while reducing donor site burden, shortening length of stay, and lowering hypertrophic scarring rates.
Key Highlights:
- ASCS produces 80:1 expansion from minimal donor skin vs. traditional meshed STSG
- Point-of-care preparation with no specialist lab infrastructure required
- Demonstrated efficacy in burns, traumatic full-thickness wounds, and chronic nonhealing wounds
- Reduces donor site morbidity, operative time, and hypertrophic scarring incidence
- Relevance: Reframes ASCS not as an adjunct but as a fundamentally different wound closure strategy
