Low-level transgene efficiency is one of the main obstacles in ex vivo nonviral vector-mediated gene transfer into primary human skeletal myoblasts (hSkMs). We optimized the cholesterol:N-[1-(2, 3-dioleoyloxy)propyl]-N, N, N-trimethylammonium methylsulfate liposome (CD liposome) and 22-kDa polyethylenimine (PEI22)- and 25-kDa polyethylenimine (PEI25)-mediated transfection of primary hSkMs for angiogenic gene delivery. We found that transfection efficiency and cell viability of three nonviral vectors were cell passage dependent: early cell passages of hSkMs had higher transfection efficiencies with poor cell viabilities, whereas later cell passages of hSkMs had lower transfection efficiencies with better cell viabilities. Trypsinization improved the transfection efficiency by 20% to 60% compared with adherent hSkMs. Optimum gene transfection efficiency was found with passage 6 trypsinized hSkMs: transfection efficiency with CD lipoplexes was 6.99 +/- 0.13%, PEI22 polyplexes was 18.58 +/- 1.57%, and PEI25 polyplexes was 13.32 +/- 0.88%. When pEGFP (a plasmid encoding the enhanced green fluorescent protein) was replaced with a vector containing human vascular endothelial growth factor 165 (phVEGF(165)), the optimized gene transfection conditions resulted in hVEGF(165) expression up to Day 18 with a peak level at Day 2 after transfection. This study demonstrated that therapeutic angiogenic gene transfer through CD or PEI is feasible and safe after optimization. It could be a potential strategy for treatment of.
