Abstract/Description: The development of novel therapies to treat chronic diabetic ulcers depends upon appropriate animal models for early stage investigation. The NONcNZO10/LtJ mouse is a new polygenic strain developed to more realistically model human metabolic syndrome and obesity-induced Type 2 diabetes; however, detailed wound healing properties have not been reported. In this report we describe a quantitative wound healing study in the NONcNZO10/LtJ mouse using a splinted excisional wound. The rate of wound healing is compared to various controls, and is also quantified in response to topical administration of normal and mutant fibroblast growth factor-1 (FGF-1). Quantitation of re-epithelialization shows that the diabetic condition in the NONcNZO10/LtJ mouse is concomitant with a decreased rate of dermal healing. Furthermore, topical administration of a FGF-1/heparin formulation effectively accelerates re-epithelialization. A similar acceleration can also be achieved by a stabilized mutant form of FGF-1 formulated in the absence of heparin. Such accelerated rates of healing are not associated with any abnormal histology in the healed wounds. The results identify the NONcNZO10/LtJ mouse as a useful model of impaired wound healing in type II diabetes, and further, identify engineered forms of FGF-1 as a potential “second-generation” therapeutic to promote diabetic dermal wound healing.
