Figure 1. Human lens epithelial cells were transfected successfully with polyamidoamine(PAMAM) and liposome. At 48 h after transfection, green (transfected) cells could be seen in the PAMAM group (A), liposome group (B) and negative control group (C) under fluorescent microscope (10×20), while there was almost no green cell in the empty control group (D).The transfection rate of the PAMAM group and liposome group at 24, 48, and 72 h after transfection were compared (E).
