The therapeutic potential of mesenchymal stem cells (MSCs) has garnered great attention in the expansive diversity of biomedical research. Despite this broad interest in stemcells, limited incorporation and poor viability are major disadvantages for accomplishing therapeutic success in the field of hMSC-based cell therapy, and an optimal approach for hMSC-based cell therapy using non-viral vectors has not been established. Hence, we examined the possibility of performing gene therapy using the biodegradable polymeric non-viral vector Arginine-grafted poly (cystaminebisacrylamide-diaminohexane) (ABP)-conjugated poly (amidoamine) (PAMAM) dendrimer (PAM-ABP) in hMSCs. PAM-ABP formed compact nanosized polyplexes and showed low cytotoxicity compared to bPEI 25k and Lipofectamine (R) 2000 in hMSCs. Although the cellular uptake was similar, the transfection efficiency and VEGF expression of PAM-ABP using gWiz-Luc and p beta-VEGF were higher than those of the control groups. Although hMSCs were transfected, their stem cell characteristics were retained. Our results suggest that PAM-ABP has the ability to deliver a therapeutic gene in hMSCs. (C) 2015 Elsevier B.V.
