Creating an Extremely Long-lasting Neuroischemic Wound Model.

In wound study and dressing development, a lack of a suitable animal model that can recapitulate the complex pathophysiology of human chronic wounds has been a major hurdle. Chronic wounds are defined as wounds that heal with a significant delay, usually over a period >2-3 months, but no current animal wound model has such a longischemia. After a longexploration, our group has developed an animal wound model with ischemia and nerve damage lasting for at least 6 months. This model can be easily combined with other conditions such as diabetes and aging for wound mechanistic study and critical testing of dressings. This report presents the method that has significant utility in evaluating therapies that could become the future standard for screening all new wound dressings.
