Cationic liposome interaction with HeLa cells. (a) Graphic illustration of the intracellular cycle of cationic liposomes in HeLa cells. (b) Confocal microscopy image of HeLa cells exposed to DiI-labelled cationic liposomes (red channel, in boxes). (c) TEM image of the as-prepared cationic liposomes. (d) HeLa cell viability after cationic liposome exposure. (e) Phase contrast image of HeLa cells exposed to the cationic liposomes for 72 h. (f) Comparative study of the cell cycle between HeLa cells with CLP by flow cytometry.
