MTS assay using hADMSCs analyzing the cytotoxicity of PEI/pDNA complexes at N/P ratios of 5 and 10 and at 1 μg and 5 μg of pDNA. Significant differences between the treatments and untreated cells were assessed by one way ANOVA followed by Tukey’s post-test (**p<0.01). Values are expressed as mean ± SEM.
