Fig. 7From: In vitro and in vivo uptake studies of PAMAM G4.5 dendrimers in breast cancerCellular uptake of PAMAM G4.5-piperazinyl-FITC by 4T1 cells at 24 h incubation. a FITC stain (green), b DAPI counterstain (sky blue) and c merge. As it can be seen from the image, PAMAM G4.5-piperazinyl-FITC dendrimers were uptake by the cells. Magnification: 80×. Scale bar 20 μmBack to article page
