A recent article, “The TallyHo Polygenic Mouse Model of Diabetes: Implications in Wound Healing” (Plast Reconstr Surg. 2011;128:427e–437e),1 described the use of the TallyHo/JnJ mouse as a diabetic mouse model. The article does not specify the sex of the TallyHo mice. This is an important distinction because male TallyHo mice are diabetic, whereas female TallyHo mice are not. In our laboratory at New York University Institute of Reconstructive Plastic Surgery, we worked extensively with female TallyHo mice in our wound healing and obesity research specifically because they provide an excellent model of obese mice that are not diabetic—a rare find. Female TallyHo mice provide an ideal mouse model for studying obesity without diabetes. In our laboratory, we have measured average blood glucose levels of 92 ± 23 mg/dl in female TallyHo mice. Interestingly, although blood glucose levels above 200 to 300 mg/dl are generally accepted to define diabetes in a mouse, we have not found literature that specifically defines the blood glucose level required for this diagnosis.
