 In veterinary medicine, gene therapy has become increasingly important as it provides a way to develop more specific drugs for different species. This is particularly useful when dealing with allergies or immune responses to foreign proteins. In this study, researchers created species-specific genetically engineered plasmids containing canine vascular endothelial and fibroblast growth factor genes. These plasmids were then injected into animals to treat skin, muscle, and ligament injuries. In vitro studies showed that the plasmids induced angiogenesis in mesenchymal stem cells, while in vivo studies showed that the plasmids stimulated skin regeneration in both rats and dogs without any adverse effects. Overall, the results suggest that gene therapy could provide a promising new treatment option for veterinary medicine. This article was authored by E. U. Zakharova, A. M. Amoletinov, N. M.
