Here we describe a novel diabetic murine model utilizing hairless mice for real-time, non-invasive, monitoring of biofilm wound infections of bioluminescent Pseudomonas aeruginosa. This method can be adapted to evaluate infection of other bacterial species and genetically modified microorganisms, including multi-species biofilms, and test the efficacy of antibiofilm strategies.

FAQs
Persistent inflammation can keep repair from progressing normally by disrupting coordination among healing stages. In a Chronic Wound Model, this feature provides a way to examine how prolonged inflammatory activity relates to impaired re-epithelialization, altered extracellular-matrix remodeling, and inadequate vascular recovery. Studying these linked changes helps researchers investigate failure of tissue repair rather than isolated cellular behavior.
Extracellular-matrix remodeling helps organize the tissue environment during repair, so altered remodeling can contribute to prolonged nonhealing behavior. Chronic Wound Models allow researchers to examine this process alongside inflammation and re-epithelialization rather than as a separate event. That integrated view is useful for identifying how disrupted tissue structure contributes to failed healing and for evaluating strategies intended to improve repair.
Re-epithelialization reflects restoration of the tissue surface, while vascular recovery reflects restoration of adequate blood-vessel support. When either process is impaired, coordinated healing can fail; when both are disrupted, the model captures multiple biological features of chronic wounds. Measuring these outcomes helps researchers connect cellular and tissue-level changes with the overall success or persistence of repair.
The research question should determine whether investigators use cultured cells, engineered tissues, or animal injury systems. Cultured cells can represent selected cellular behaviors, while engineered tissues and animal systems offer other experimental settings for examining wound biology. Choosing among them allows studies to focus on a specific mechanism, evaluate tissue-level responses, or compare healing outcomes in a broader biological context.
A study should first identify the repair failure or biological process it aims to investigate, then select a model system that represents that question. Researchers can examine sustained inflammation, re-epithelialization, extracellular-matrix remodeling, or vascular recovery, and compare resulting healing outcomes. This approach keeps the model aligned with the mechanism under study and the type of evidence required.
These models provide experimental settings for testing whether biomaterials or therapeutics influence the biological features associated with prolonged nonhealing. Researchers can examine changes in inflammation, surface restoration, matrix remodeling, vascular recovery, and overall healing outcomes. Such comparisons help connect an intervention's effects on wound biology with its potential to support improved tissue repair.
