Identification of nanoATV within Kupffer cells.

<p>Confocal microscopy images of cryo-sectioned liver collected 12 h after intraperitoneal injection of nanoATV. Immunofluorescence images are as follows: <b>(A)</b> Cell nuclei stained with DAPI (blue); <b>(B)</b> Macrophages (Kupffer cells) stained with F4/80 and Alexa Fluor 488 (green); <b>(C)</b> NanoATV labeled with CF633 (pink); <b>(D)</b> Overlay of F4/80-labeled macrophages and CF633-labeled nanoATV. Images were acquired with a LSM 710 confocal microscope at 40x. (scale bars = 10 μm).</p>
