Abstract

The disease diabetes depictures a heterogeneous group of metabolic disorders that arise as a result of hyperglycemia due to the deficit of secretion and/or insulin action. How it promotes systemic alterations, short and long-term complications have high impact for de health system of countries. Among its long-term complications, foot ulcer is the one that generates more hospital admissions. These wounds often become chronic due to a series of molecular and cellular aberrations of the healing process, being the main mechanisms the following: high concentrations of matrix metalloproteinases (MMPs), neuropathy, high probability of infection and non-physiological inflammatory response, oxidative stress, excessive formation of AGEs (advanced glycoxidation end-products), deficient neoangiogenesis, imbalance between metabolism and nutrient delivery, inadequate concentrations of growth factors and gene expression regulators, and cellular abnormalities. With better scientific understanding of these events and physiological healing, new approaches to disease can provide more satisfactory results to the treatment.
