Rapid Construction of Tissue-engineered Skin for Repairing Difficult-to-heal Wounds: A Multicenter Real-world Study
Обзор
This multicenter real-world study evaluates the efficacy and safety of a novel technique for rapid intraoperative construction of tissue-engineered skin using autologous epidermal stem cells (EpiSCs) for repairing difficult-to-heal wounds. Eligible patients are randomized to receive either: (1) the experimental intervention (rapidly constructed EpiSCs-loaded scaffold combined with split-thickness skin graft via one-step or two-step procedure), or (2) control intervention (acellular scaffold combined with split-thickness skin graft). The primary outcome is the complete wound healing rate at 4 weeks post-surgery. Secondary outcomes include wound recurrence, scar quality (VSS/POSAS), functional recovery (sweat test), mortality, amputation rate, and safety profile.
Вмешательства
- Процедура Rapid Tissue-Engineered Skin
Autologous split-thickness skin (0.15-0.2 mm) is harvested from the donor site at a donor-to-wound area ratio of 1:20-30. The harvested skin is processed using a specialized cell sorter to isolate autologous epidermal stem cells (EpiSCs) with \>93% viability within 30 minutes. The cell suspension is adjusted to a concentration of ≥1×10⁶ cells/mL and loaded onto a tissue-engineered scaffold via spraying or immersion (3-5 minutes). The cell-seeded scaffold is then applied to the wound bed. Dependi - Процедура Traditional Composite Skin Graft
The same tissue-engineered scaffold (without cell loading) is used. Autologous split-thickness skin graft (0.15-0.2 mm thickness) is harvested. The acellular scaffold is applied to the debrided wound bed followed by coverage with the split-thickness skin graft. The surgical procedure, postoperative wound care, negative pressure wound therapy (-100 to -125 mmHg when indicated), and follow-up protocol are identical to those in the experimental arm. This comparator represents the current standard o
