Rapidly constructed tissue-engineered skin to repair hard-to-heal wounds

Rapid Construction of Tissue-engineered Skin for Repairing Difficult-to-heal Wounds: A Multicenter Real-world Study

Not applicable Interventional First Affiliated Hospital, Sun Yat-Sen University · NCT07562230

This trial tries a fast, personalized skin graft made from your own epidermal stem cells to see if it heals hard-to-heal wounds faster and with fewer complications than a standard graft.

What this trial studies

This is a multicenter, randomized real-world study comparing a rapidly constructed epidermal stem cell (EpiSC)-loaded scaffold combined with split-thickness skin graft (one-step or two-step) versus an acellular scaffold combined with split-thickness skin graft. Eligible patients with single-area wounds of 10–100 cm² (acute burns, traumatic defects, post-scar resection, diabetic foot ulcers, pressure injuries, or vascular ulcers) whose wound beds are prepared and infection-controlled will be randomized. The primary outcome is complete wound healing at 4 weeks post-surgery, with secondary outcomes including wound recurrence, scar quality (VSS/POSAS), functional recovery (sweat test), mortality, amputation rate, and safety. Safety monitoring will include adverse events related to the scaffold, infection, and organ/systemic complications.

Who should consider this trial

Good fit: Ideal candidates are patients of any age with a single 10–100 cm² acute or chronic wound requiring surgical repair whose wound bed is clean and infection-controlled and who can consent to the procedure and long-term follow-up.

Not a fit: Patients with severe immunosuppression, uncontrolled systemic infection, organ failure, malignant disease, allergy to scaffold or collagen materials, pregnant or lactating women, or those unable to comply with treatment or follow-up are unlikely to benefit.

Why it matters

Potential benefit: If successful, this approach could speed complete wound closure, reduce scarring, and lower rates of infection, amputation, or death for patients with difficult-to-heal wounds.

How similar studies have performed: Related tissue-engineered skin approaches using cultured autologous epidermal cells have shown promise in small studies, but rapid intraoperative construction with EpiSC-loaded scaffolds is a newer technique with limited large-scale evidence.
