Figure 6From: Co-delivery of docetaxel and endostatin by a biodegradable nanoparticle for the synergistic treatment of cervical cancerConfocal laser scanning microscopy of HeLa cells. This is after incubation with loaded-coumarin-6-TPGS-b-(PCL-ran-PGA)/PEI-pDSRED NPs at 37°C. The cells were stained by DAPI (blue), and the plasmids pDsRED-loaded-TPGS-b-(PCL-ran-PGA)/PEI NPs are red. The cellular uptake was visualized by overlaying images obtained.
