Staining of cardiac cells with 7. Cardiac cells treated with cytosine arabinoside (10 μM) one day after plating for 72 h and then stained with the fluorescent dendrimer derivative 7 (10 pM) for 20 min at room temperature. For counterstaining we used Hoechst 33342 (10 uM), which stains the nuclei of the cells. The cells were washed 3–4 times with PBS and photographed using a confocal microscope microscope at 405/450 nm for Hoechst and 488/520 nm for 7. A. Hoechst 33342 stain, B. AlexaFluor fluorescence, C. Phase contrast.
