Figure 5

Light (left images in each pair) and fluorescent (right images in each pair) microscopy of BT-20 cells incubated with Rh-PE-labeled PEG-PE/ST/paclitaxel micelles and PEG-PE/ST/LL/paclitaxel micelles for 0.5, 2, and 4 h. Arrows on fluorescent microscopy images show: fluorescent endosomes in cells incubated with PEG-PEG-PE/ST/LL/paclitaxel micelles for 0.5 h and with PEG-PE/ST/paclitaxel micelles for 2 h; partially degraded endosomes in cells incubated with PEG-PE/ST/LL/paclitaxel micelles for 2 h; fused late endosomes in cells incubated with PEG-PE/ST/paclitaxel micelles for 4 h; small fluorescent structures in cells incubated with PEG-PE/ST/LL/paclitaxel micelles for 4 h.
