Increased Matrix Metalloproteinase-9 Predicts Poor Wound Healing in Diabetic Foot Ulcers

We thank the authors for their comment (1) on our study (2) and we agree that the pathophysiology of diabetic foot ulcers is complex and not well understood. We recognize that we are not the first to establish a potential role for matrix metalloproteinase-9 (MMP-9) in chronic wound healing. However, we report that its measurement...
