Figure 5From: Paclitaxel and etoposide co-loaded polymeric nanoparticles for the effective combination therapy against human osteosarcoma Cellular uptake analysis. (A) Flow cytometry analysis of in vitro cellular uptake of PLGA NP in a time dependent manner. The PLGA nanoparticle was loaded with Rhodamine B as a fluorescent dye. (B) Confocal microscopy images of MG63 cells. Cells were treated with PTX-ETP/PLGA NP and incubated for 1Â h. Nuclei were stained with DAPI and Rho B fluorescence was observed in the cytoplasm.Back to article page
