Fig. 3. Characterization of concentrated niosome formulations. (A and B) TEM images of non-concentrated (A) and concentrated (B) formulations based on niosome 1 at 10 000× magnification. Scale bars: 500.0 nm. (C) Transfection efficiency 48 h post-exposure of mMSCs to nioplexes based on concentrated and non-concentrated niosome 1 at 2/1 cationic lipid/DNA mass ratio (w/w). *p < 0.05 for transfection efficiency between niosome formulations, #p < 0.05 for transfection efficiency of all niosome formulations relative to the positive control.
