2017
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.

There is an update associated with this article. Please click here to see the update. Chronic wounds are developed from acute wounds on a diabetic mouse model by inducing high levels of oxidative stress after a full-thickness cutaneous wound. The wound is treated with inhibitors for catalase and glutathione peroxidase, resulting in impaired healing and biofilm development by bacteria present in the skin microbiome.

An example of adenoviral gene therapy in the human diabetic organ-cultured corneas is presented towards the normalization of delayed wound healing and markedly reduced epithelial stem cell marker expression in these corneas. It also describes the optimization of this process in stem cell-enriched limbal epithelial cultures.

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.

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.
FAQs
Persistent hyperglycemia can damage blood-vessel function, limiting tissue oxygenation where repair is needed. It can also disrupt immune responses and prolong inflammation, preventing the wound from progressing efficiently through repair. Diabetic wound research therefore examines vascular function, oxygen availability, immune activity, and inflammatory persistence as connected mechanisms that may identify targets for improved ulcer treatment.
Neuropathy can prevent a person from noticing an injury promptly, allowing it to remain untreated or worsen through repeated pressure. This makes sensory loss an important factor in diabetic wound progression, separate from the biological effects of hyperglycemia. Research findings can support better risk assessment and wound-care strategies aimed at identifying vulnerable injuries earlier.
Key targets include re-epithelialization, angiogenesis, infection control, and tissue regeneration. Re-epithelialization concerns restoration of the wound surface, while angiogenesis refers to formation of new blood vessels. Examining these processes helps researchers determine whether a therapy addresses closure, tissue oxygenation, infection, or broader regeneration, rather than relying on wound appearance alone.
Disrupted immune responses may weaken the wound’s ability to manage biological challenges, while prolonged inflammation can delay progression toward closure. Together, these abnormalities help explain why diabetic wounds may become chronic and vulnerable to complications. Studying both processes allows investigators to evaluate treatments designed to improve infection control and restore more effective tissue repair.
Investigators combine clinical studies with cellular models, biomaterials, and animal models to examine wound repair and test therapeutic strategies. These approaches provide complementary evidence about biological responses, material-based interventions, and treatment performance before findings support improved care. The overall research process connects controlled experimentation with clinically relevant questions about diabetic ulcers and healing.
Cellular models allow researchers to examine wound-repair behavior under controlled experimental conditions, while biomaterials provide a way to investigate material-based strategies for supporting healing. Used alongside other research approaches, they help evaluate effects on processes such as re-epithelialization, angiogenesis, infection control, and tissue regeneration. Their findings can guide development of targeted treatments.
Findings from this field support improved risk assessment, wound-care strategies, and development of targeted treatments for diabetic ulcers. Clinical studies connect research observations to patient care, while laboratory and animal models help investigate mechanisms and candidate interventions. This combined evidence is relevant to preventing infection, chronic ulcer progression, and limb-threatening complications in people with diabetes.
