ABSTRACT
Human hypertrophic scars are the result of imperfect healing of skin, which is particularly evident from the scars developing after severe burns. In contrast, mouse and rat full-thickness skin wounds heal normally without forming visible scar tissue, which reduces the suitability of rodent models for the study of skin scarring. We here provide a simple procedure to splint the edges of full-thickness rodent skin with a sutured plastic frame that prevents wound closure by granulation tissue contraction. The resulting mechanical tension in the wound bed and the lack of neo-epithelium amplify myofibroblast formation and generate hypertrophic features, not unlike those of human skin. In addition to producing scar tissue, the splint provides a reservoir that can be used for the delivery of cellular and acellular wound treatment regimen. Despite being simple and almost historical, wound splinting is a robust and reliable model to study myofibroblast biology.
