Abstract (original English)
We compared two methods of transfection (lipofection and electroporation) with plasmid containing VEGF121 gene in four cultures of mesenchymal stem cells from the human adipose tissue. The efficacy of transfection after 1 day, the dynamics of plasmid elimination after 3, 6, 9 days, and expression of the target gene were evaluated. Transfection by both methods failed in one of 4 cultures. Analysis of the plasmid elimination dynamics showed that the content of plasmids introduced by both methods decreased by 30-69% in all cultures by day 3 and then remained unchanged from day 3 to day 9. The expression of the target gene did not correlate with the content of plasmids in cells and varied by 2-10 times in control cells and cells transfected by both methods. Fluctuation of VEGF121 expression was not related to methylation.
