Intracellular localization of QD-COOH in undifferentiated Caco-2 cells. Confocal images of undifferentiated Caco-2 cells incubated for 3 days with QD-COOH (45 µg cadmium ml−1). Lysosomes (Lamp1) are depicted in grey. a Orthogonal views (xy, xz and yz) showing the intersection planes at the position of the yellow cross-hair. b Maximum intensity projection of the same z-stack. QDs (magenta), cell membrane (cyan), and nucleus (yellow)
