Cell-based delivery system is a promising strategy to protect therapeutic agents from the immune system and provide targeted delivery. Mesenchymal stem cells (MSCs) have recently been introduced as an encouraging vehicle in cell-based gene therapy due to their unique features
Poly-(amidoamine) (PAMAM) and poly-(propylenimine) (PPI) are the two most widely investigated dendrimers for drug and gene delivery. In order to enhance DNA transfection activity of these dendrimers, generation 3 and 4 PAMAM and generation 4 and 5 PPI were modified

Branched polyethylenimine (PEI) is extensively used as a polycationic non-viral vector for gene delivery. Polyplexes formed with PEI are believed to be released from endocytotic vesicles by the osmotic burst mechanism in the rate-limiting step in transfection. Increasing the buffering
