Abstract (original English)

Gene therapy is one of the most promising approaches in regenerative medicine for the restoration of extensive bone defects in dentistry and maxillofacial surgery. Matrices obtained using three-dimensional printing from bioresorbable polymers, impregnated with adenoviral constructs with genes for osteoinductive factors, can ensure safe and effective formation of bone tissue. To study the properties of three-dimensional matrices based on polylactic-co-glycolic acid and adenoviral constructs with the GFP gene in vitro. The matrices were obtained by antisolvent three-dimensional printing. Transduction efficiency was assessed by fluorescence microscopy and flow cytometry. The cytocompatibility of the matrices was assessed by the MTT test and by staining cells with fluorescent dyes. Matrices based on polylactic-co-glycolic acid have high cytocompatibility on adipose tissue-derived mesenchymal stem cells. Impregnation of adenoviral vectors with the green fluorescent protein gene in 3D matrices ensures the release of viral particles within a week, maintaining their high transducing ability. The developed method for obtaining gene-activated matrices can serve as the basis for the creation of effective osteoplastic materials for bone regeneration. Генная терапия является одним из наиболее многообещающих подходов регенеративной медицины для лечения обширных костных дефектов в стоматологи
