The article has analyzed the world experience and main trends in the preparation of cadaveric skin for use in the treatment of patients with wounds of various etiologies. The history of the question is described from the first attempts of transplantation of the native skin to the creation of specialized banks of allogenic decellularized tissue grafts. Presented are the modern approaches of donor material conservation, specifically, to the principle and topical question: whether the viability of the cells should be preserved in the graft, or it is more efficient to transplant the skin devoid of cellular elements. The advantages and disadvantages of lyophilized grafts have been described, namely the possibility of longterm storage, but loss of elasticity, after rehydration. The methods of cryoconservation of cutaneous allografts, their properties, and acceptable methods of sterilization have been discussed. A perspective technology of graft decellularization has been assessed and the methodologies of their manufacturing have briefly been presented.

Morphofunctional evaluation of the effect of biological dressing with collagen-1 on healing of 3A degree burn wound in outbred and mutant Hr(hr)/Hr(hr)(hairless) mice was carried out by the histological method and optic radioautography. A pronounced stimulatory effect of the dressing on skin regeneration in mice was demonstrated. According to radioautography data, early dressing of the burn wounds in Hr(hr)/Hr(hr)mice led to active proliferation of epithelial cells in dermal cyst and vascular endotheliocytes. The possible mechanisms of the stimulatory effect of collagen-based dressing on wound healing are discussed.
