[Ultrastructural changes of vascular endothelium in patients with chronic ischemia of the extremities after conduction of multipotent stromal cells from adipose tissue transplantation].
Taking into account the impossibility of performance in some situations of reconstructive operative interventions on arteries, it is necessary to look for new methods of indirect revascularization for the extremities ischemia. Adipose tissue constitutes an accessible and sufficient source of multipotent stromal cells (MSC). Experimental investigations were made in a frame of preclinical trial on laboratory animals with the extremity ischemia simulation, and there was proved the essential stimulation of angiogenesis processes after transplantation performance of stromal-vascular fraction of adipose tissue. The work objective was to study the influence of own adipose tissue MSC transplantation on vascular endothelium changes in patients, suffering chronic ischemia of the extremities. Using electron microscopy method there was proved on microstructural level, that in clinical environment the patients, suffering chronic ischemia of the extremities of various etiology, gain undoubted effect of MSC autotransplantation performed with the objective to stimulate the processes of angiogenesis in the ischemic affection region.
