摘 要:We previously demonstrated that gene-modified umbilical cord blood mononuclear cells overexpressing a combination of recombinant neurotrophic factors are a promising therapeutic approach for cell-mediated gene therapy for neurodegenerative diseases,neurotrauma,and *** this study,using a mini pig model of spinal cord injury,we proposed for the first time the use of gene-modified leucoconcentrate prepared from peripheral blood in the plastic blood bag for personalized ex vivo gene *** obtained from mini pig peripheral blood was transduced with a chimeric adenoviral vector(Ad5/35 F)that carried an enhanced green fluorescent protein(EGFP)reporter gene in the plastic blood *** day after blood donation,the mini pigs were subjected to moderate SCI and four hours post-surgery they were intravenously autoinfused with gene-modified leucoconcentrate.A week after gene-modified leucoconcentrate therapy,fluorescent microscopy revealed EGFP-expressing leucocytes in spinal cord at the site of contusion *** the spleen the groups of EGFP-positive cells located in the lymphoid follicles were *** vitro flow cytometry and fluorescent microscopy studies of the gene-modified leucoconcentrate samples also confirmed the production of EGFP by ***,the efficacy of leucocytes transduction in the plastic blood bag and their migratory potential suggest their use for temporary production of recombinant biologically active molecules to correct certain pathological *** paper presents a proof-of-concept of simple,safe and effective approach for personalized ex vivo gene therapy based on gene-modified leucoconcentrate *** animal protocols were approved by the Kazan State Medical University Animal Care and Use Committee(approval No.5)on May 27,2014.
