Abstract (original English)

Systemic and local radiation injuries caused by nuclear power reactor accidents, therapeutic irradiation, or nuclear terrorism should be prevented or properly treated in order to improve wound management and save lives. Currently, regenerative surgical modalities should be attempted with temporal artificial dermis impregnated and sprayed with a local angiogenic factor such as basic fibroblast growth factor, and secondary reconstruction can be a candidate for demarcation and saving the donor morbidity. Human mesenchymal stem cells and adipose-derived stem cells, together with angiogenic and mitogenic factor of basic fibroblast growth factor and an artificial dermis, were applied over the excised irradiated skin defect and were tested for differentiation and local stimulation effects in the radiation-exposed wounds. The perforator flap and artificial dermal template with growth factor were successful for reconstruction in patients who were suffering from complex underlying disease. Patients were uneventfully treated with minimal morbidities. In the experiments, the hMSCs are strongly proliferative even after 20 Gy irradiation in vitro. In vivo, 4 Gy rat whole body irradiation demonstrated that sustained marrow stromal (mesenchymal stem) cells survived in the bone marrow. Immediate artificial dermis application impregnated with cells and the cytokine over the 20 Gy irradiated skin
