Fig. 2. Screening of niosome formulations. (A) Size. (B) Zeta potential. (C) Transfection efficiency 48 h post-exposure of mMSCs to nioplexes based on niosomes 1, 2 and 3 at cationic lipid/DNA mass ratios (w/w) 2/1, 15/1 and 18/1, respectively. Positive (Lipofectamine 2000™ at a cationic lipid/DNA mass ratio of 2/1) and negative (no DNA) controls are shown for reference. *p < 0.05 for transfection efficiency between niosome formulations, #p < 0.05 for transfection efficiency of all niosome formulations relative to the positive control.
