Fig. 8From: Effects of the surface charge of polyamidoamine dendrimers on cellular exocytosis and the exocytosis mechanism in multidrug-resistant breast cancer cellsCellular uptake confocal images of the distribution of PAMAM dendrimers in MCF-7/ADR cells. PAMAM dendrimers are green while the nuclei are stained blue using Hoechst 33258. The scale bar is 50 μmBack to article page
