Fig. 5 |

a, Immunofluorescence images of human enterocytes stained for EPCAM (red), DAPI (blue) and either ACE2 (green in a, c) or SARS-CoV-2 N (green in b, d) in intestinal biopsies taken 92 d after onset of COVID-19 symptoms in participant CGI-088, in the terminal ileum (a, b) or duodenum (c, d). Regions in white boxes in the right panels of a, c are shown expanded in b, d, respectively. Arrows indicate enterocytes with detectable SARS-CoV-2 antigen. Scale bars, 100 μm. The experiments were repeated independently at least twice with similar results.
