Figure 2.
The intracellular localization of the silk particles by CLSM. SKBR3 cells were incubated with spheres at 37 °C for 4 h, followed by staining with LysoTracker Green for the endo-/lysosome visualization. Red, silk spheres labeled with ATTO647N; green, endo-/lysosomes stained with LysoTracker Green; blue, nuclei stained with DAPI. Scale bar: 10 μm.
