The results of three-year research on the use of allogeneic mesenchymal stem cells of adipose tissue (AMSCs) in the treatment of skin burns of II-III degree are presented. in a complex with wounds dressing of nanofibers chitosan and copolyamide, hyaluronic acid. It was found that with surgical necrectomy, introduction of AMSCs and substitution of defects with natural polymer coatings, the healing time is reduced by 89% (p < 0.05). Isolated administration of MSC reduces the healing period by no more than 5% (p > 0.05). The combined use of wounds dressings of nanofibers chitosan and copolyamide with MSC accelerates the regeneration process by 26% (p < 0.05), with the introduction of AMSCs accelerating the development of granulation tissue by the fifth day of observation by 83% (p < 0.01). Joint use of wound coverings on the basis of hyaluronic acid with AMSCs is accompanied by an increase in the number of vessels of the microcirculatory bed in the defect area by 185% (p < 0.01). Clinical evaluation of the effectiveness of drugs with stem cells - a gel for topical application and a suspension of MSC LC for injection administration demonstrate their ability to optimize regeneration in the burn zone. Application of gel with AMSCs reduces the duration of epithelialization of border (dermal) burns by 2.2-2.4 times, with the final healing period being reduced by 59% (p < 0.01) and the suppuration frequency by 30% (p < 0.05). The introduction of a suspension of AMSCs into the zone of deep burn increases the frequency of engraftment of autografts, stimulates angiogenesis and proliferation of fibroblasts in the superficial and deep layers of the dermis. In the area of MSC administration, the LC perfusion level and the amplitude of blood flow fluctuation are twice as high as the values in the zones without the introduction of cells.
