Experimental models of a transfer of stem cells for therapeutic purposes Abstract Stem cell therapy currently represents a standard procedure of treating a wide variety of hereditary diseases and serious injuries. Development of the most suitable way of transfer of stem cells into the patient body remains very important question concerning this type of therapy. In our experiments we used nanofiber scaffolds for stem cell cultivation and their subsequent transfer. These nanofibers were prepared by the original needleless electrospun NanospiderTM technology. Allogeneic cornea or skin graft were transplanted from B6 mice to BALB/c mice. The grafts were covered by a nanofibrous scaffold with cultivated stem cells. Stem cells were stained by an imunofluorescent dye to enable us to monitore their migration from nanofibers into tissues and consequent distribution in the body and characterize changes of this distribution in the time. The methods of ELISA and PCR were used to confirm that mesenchymal stem cells support the production of antiinflammatory cytokines IL-4 and IL-10 and contribute to inhibition of production of proinflammatory cytokines IL-1, IFNγ and inducible nitric oxide synthase. We confirmed an important beneficial role of nanofiber scaffolds in transplantation of mesenchymal stem cells. Nanofiber...
