RESEARCH OUTREACH - Wound healing is highly regulated, but oxidative stress (OS) can disturb this healing process in chronic wounds. To better understand the process of initiating chronicity, Dr Manuela Martins-Green and her colleagues at the University of California investigated the impact of increased OS levels on wound healing by stimulating chronic wound development in a diabetic mouse model. The team provides insight into new ways we can approach the treatment of chronic wounds, especially in patients with diabetes.
