Abstract (original English)

Background aims Recombinant adenoviruses have tremendous potential in both gene therapy research and therapeutic applications. Mesenchymal stromal cells have a set of several properties that make them ideally suited for both regenerative medicine and gene and drug delivery. A limitation of adenoviral-mediated gene transfer is indeed the poor transduction rate of cells with low or no levels of the specific adenoviral cell surface receptor coxsackie virus and adenovirus receptor (CAR), such as human mesenchymal stromal cells. In the present work, we tried to increase the adenovirus transduction level and mediated gene delivery of human adipose stem cells with the use of valproic acid (VPA) and determined the proper concentration and duration of treatment alone or in combination with ViraDuctin adenovirus transduction reagent. Methods Green fluorescent protein-expressing recombinant adenovirus was propagated. The effects of various doses and exposure periods of VPA on CAR expression in human adipose stem cells were speculated by quantitative real-time polymerase chain reaction and adenoviral transduction rate by flow cytometry in different doses and time intervals of VPA and in combination with ViraDuctin transduction reagent. Results CAR messenger RNA upregulation through VPA was observed in human adipose stem cells; it was a dependent factor of dose and exposure time. Consequent
