Skin Rejuvenation Using Autologous Cultured Fibroblast Grafting.
Cureus
December 2024
Plastic and Reconstructive Surgery, St. Marianna University School of Medicine, Kawasaki, JPN.
Background: Recently, autologous cultured fibroblast and platelet-rich plasma (PRP) therapies have been attempted for skin rejuvenation. Unlike PRP, grafted fibroblasts not only produce connective tissue but also influence the surrounding environment through a paracrine effect. Fibroblast-derived cytokines interact with and are modulated by neighboring tissue-constituting cells.

For pediatric patients with full-thickness burns, achieving adequate dermal regeneration is essential to prevent inelastic scars that may hinder growth. Traditional autologous split-thickness skin grafts alone often fail to restore the dermal layer adequately. This study evaluates the long-term effect of using a NovoSorb Biodegradable Temporizing Matrix (BTM) as a dermal scaffold in four pediatric patients, promoting dermal formation before autografting.

Ann Burns Fire Disasters

Division of Plastic and Reconstructive Surgery, Department of Precision and Regenerative Medicine and Jonic Area, University of Bari, Bari, Italy.
Deep intermediate burns of the hand are a challenge for both the functional and aesthetic result. In this study we compare the efficacy of early selective enzymatic escarolysis followed by the application of stromal vascular fraction (SVF) extracted from autologous adipose tissue on a dermal substitute scaffold (DS) versus reconstruction by partial thickness skin grafts (PTSG). We enrolled all patients admitted to our referral Burn Center from September 2020 to January 2022 with deep intermediate burns of the hands: clinical data were collected, then the first group of 4 patients were treated with PTSG surgical reconstruction, and the second group of 7 patients with DS+SVF.

Plast Reconstr Surg Glob Open
December 2024
Medical Affairs Department, AVITA Medical, Valencia, CA.
Hard-to-heal wounds represent a global and growing medical and economic burden. Skin autografting is a useful treatment option but is often limited by donor site morbidity, logistical considerations, and grafting success in compromised wound beds. Combining autologous skin cell suspension (ASCS) technology with minced dermal grafts can allow for dermal elements and epithelial healing as well as closed donor sites.

Front Transplant
December 2024
Department of Surgery, University of Colorado Denver Anschutz Medical Campus, Aurora, CO, United States.
Introduction: As research advances in vascularized composite allotransplantation (VCA), large animal models are essential for translational studies related to immune rejection and graft survival. However, procurement of large flaps can cause significant defects, complicating wound closure and increasing postoperative risks. This study details the surgical techniques and outcomes of autologous vertical rectus abdominis myocutaneous (VRAM) flap transplantation and neck flap isolation with induced ischemia in a swine model.
