Figure 5. PEG-PLGA nanoparticles are internalized and can be localized in the lysosomes, mitochondria, and endoplasmic reticulum.
Confocal microscopy images of ARPE-19 cells treated with Rhodamine 6G-loaded PEG-PLGA NPs and stained with different organelle stains. (A-C) Rhodamine 6G-loaded PEG-PLGA NPs can be observed at all z-planes inside the cells. These NPs can also be co-localized in the lysosomes (D-F), mitochondria (G-I), and endoplasmic reticulum (J- L), as seen in the merged signal with their respective trackers.
