Abstract

Background: This study focuses on developing a model of a non-healing wound that recapitulates the pathogenesis of the corresponding human pathology. Methods: A non-healing wound was modeled in mice with streptozotocin-induced diabetes. The following parameters were assessed: re-epithelialization, epidermal hypertrophy, wound contraction, relief index, angiogenesis, and granulation tissue maturation. These parameters were compared between diabetic mice and healthy controls. Results: The proposed model demonstrated a significant delay in regenerative processes compared to healthy animals. Conclusions: These findings support the relevance of this model to human pathology and indicate that it may be applicable for preclinical studies of drugs aimed at promoting wound regeneration.
