The results indicated that inhibition of free radical processes by injections of α-tocopherol in normal pregnancy led to disorders in the feto-maternal circulation, which was proven by morphological changes in the placenta. The disorders in the uteroplacental circulation manifested in the development of small-for-date fetuses and erythrocytosis.We studied the effect of transfection of PC-3 prostate cancer cells with a plasmid encoding shRNA complimentary to a fragment of integrin β4 (ITGB4). The results attest to considerable changes in the transcriptome of transfected cells. For instance, compensatory changes in the expression of integrin family genes were found.The possibility of pregnancy and labor was evaluated and tissue changes after injection of autologous bone marrow multipotent mesenchymal stromal cells with transfected GFP gene were studied in rats with experimental hydrometra. Injection of stromal cells to the uterine cicatrix increased the number of vessels (vascular walls or their elements) formed de novo with participation of injected cells. The animals produced progeny 2 estrous cycles earlier, the percentage of "puerperal" rats in this group was higher, their progeny was more numerous and they had the maximum numbers of little rats. The maternal mortality was lower after injection of stromal cells. Injection of stromal cells led to development of a trend to more rapid reparative processes in the uterus in animals with cicatricial stenosis of its lumen.We compared the structure and mechanical properties of scaffolds based on pure collagen, pure chitosan, and a mixture of these polymers. The role of the composition and structure of scaffolds in the maintenance of cell functions (proliferation, differentiation, and migration) was demonstra
