title: Does cell therapy and tissue engineering represent a promising treatment of diabetic foot ulcers?
abstract: Diabetes mellitus is one of the most severe and costly chronic disease of our time. Approximately 2-3% of diabetics have an active foot ulcer, and 15% of all patients with diabetes will develop an ulcer during their lifetime. Treatment of foot complications is one of the main items in the absorption of enormous economic and health resources addressed to the diabetic patients. Advances in basic science, tissue culture techniques and cell therapy promise to improve the treatment of diabetes as well as its complications, i.e. also the ischemic ulcers of the foot. At present, the isolation of any specific type of cells, their in vitro expansion and biological characterization of acquired cell population are possible. For the healing process in ischemic diabetic ulcers, stem cells, endothelial progenitor cells and fibroblasts, both in suspension or placed on an extracellular scaffold are used. This process is focused on stimulating the new blood vessels formation. This is stimulated by the paracrine secretion of multiple growth factors and their receptors. Verified are the vascular endothelial growth factor and its receptor, fibroblast growth factor, interleukin-8 and proangiogenic cytokines (Ref. 62).
