Studysummary In this study, a new cell-tissue technology using a patient's own skin to create a full-thickness skin autograft successfully treated a chronic wound larger than 200 cm², achieving complete functional skin coverage within 12 weeks and maintaining results at a 6-month follow-up. Our plain-language summary of this paper — not a Tressless recommendation.
The study provided clinical proof of concept for using an autologous homologous skin construct (AHSC) to treat chronic wounds unresponsive to traditional methods. AHSC, derived from a patient's own skin cells, was applied to a large non-healing wound, achieving complete epithelial coverage in 8 weeks and full-thickness functional skin by 12 weeks. At a 6-month follow-up, the regenerated skin was similar to native skin in sensation and hair follicle morphology. The patient preferred AHSC over split-thickness skin grafts for reduced pain and improved function and appearance. The study suggested AHSC as a promising treatment for chronic wounds, though further research was needed for patients with comorbidities.
