Nonviral Gene Delivery to Mesenchymal Stem Cells Using Cationic Liposomes for Gene and Cell Therapy

Figure 1

Differences between the percentage of GFP positive cells assessed by flow cytometry analysis (white bars) and intracellular plasmid copy number determined by RT-PCR (grey ⋄). MSCs were transfected with three different Lipofectamine/pDNA (L/D) ratios: 1, 1.25, and 2. Results are the mean of four independent experiments with standard deviation.
