Basement Membrane Regeneration for Wound Repair

Sponsor: First Affiliated Hospital, Sun Yat-Sen University

Summary

This study is a prospective, multicenter, real-world observational study. It aims to evaluate the effectiveness and safety of autologous basement membrane regeneration technology (epidermal basal cell suspension prepared using a cell sorting system) for wound repair in patients undergoing skin grafting, flap surgery, or primary suture. A total of 500 patients receiving the cell suspension therapy combined with standard surgical procedures will be enrolled from multiple hospitals across China. Their outcomes will be compared with 500 matched patients receiving standard surgical procedures alone (e.g., skin grafting, flap surgery, or suture without cell suspension). The primary outcomes include complete wound healing rate at 4 weeks (for grafted wounds) and time to complete wound closure (for sutured or flap-repaired wounds). Secondary outcomes include wound area reduction rate, recurrence rate, scar assessment (Vancouver Scar Scale), pain score (ASA), sweat function test, basement membrane integrity (histopathology with collagen IV and VII staining if clinically indicated), and safety. Patients will be followed for up to 6 months.
