The rat, due to its size, availability, and rather docile behavior, has been utilized as a research model for many years. The goal of this protocol is to utilize the rat as an ischemic skin wound healing model to provide valuable insight into the pathophysiology of chronic wounds.

Chronic wounds that are resistant to antibiotics are a major threat to the healthcare system. Biofilm infections are stubborn and hostile and can cause deficient functional wound closure. We report a clinically relevant swine model of biofilm-infected full-thickness chronic wounds. This model is powerful for mechanistic studies as well as for testing interventions.

We have developed a minimally invasive technique to create a rabbit ischemic ear wound model by dividing the central artery and nerve and the cranial neurovascular bundle. A subcutaneous tunnel then cuts all subcutaneous tissues. This procedure causes minimal skin disruption and can be safely used in diabetic animals.
FAQs
Damage exposes tissue and releases danger signals that activate innate immune pathways. Chemokines then provide recruitment cues for neutrophils and macrophages, bringing these cells into the injured area. This sequence lets a model examine how early sensing and leukocyte movement connect tissue disruption with microbial control, inflammation, and the beginning of repair.
Neutrophils and macrophages can help control contamination while also coordinating inflammation and tissue repair. The outcome therefore depends on whether the response remains protective or instead delays healing and contributes to chronic infection. Measuring these contrasting outcomes helps investigators evaluate immune-modulating treatments without treating inflammation as uniformly beneficial or harmful.
These systems differ mainly in the biological setting available for observation. Cultured cells, engineered tissues, and living organisms can each reproduce injury while providing controlled conditions for studying host-pathogen interactions. Comparing them helps investigators match the model to questions about damaged barriers, immune responses, microbial effects, or healing outcomes.
Establishing a Wound Model requires an injury system and a defined biological context: cultured cells, engineered tissues, or a living organism. The model is then used to examine how exposed tissue responds to microbes and how immune activity relates to inflammation, repair, re-epithelialization, and resulting repair outcomes.
Wound models are useful when investigators need to compare how antimicrobial strategies affect microbial control and healing, or how immune modulation changes the response to injury. Because the systems can represent cultured cells, engineered tissues, or living organisms, they support controlled examination of host-pathogen interactions alongside inflammation and repair.
Relevant outcomes include microbial control, inflammatory activity, tissue repair, and re-epithelialization, the restoration of the epithelial covering. A model can also reveal whether an intervention supports healing or produces a response associated with delayed repair and chronic infection. These readouts connect immune behavior with practical assessment of treatment effects.
