SARS-CoV-2 replicates efficiently and infects both ciliated and secretory cells in HAE cultures. In this study, we compared the characteristics of the replication dynamics, cell tropism, and morphogenesis of SARS-CoV-2 and HCoV-NL63 in HAE cells, which express the shared receptor, to better understand the pathogenesis and transmission of SARS-CoV-2. As shown in Fig. 1a , HAE cells were highly susceptible to SARS-CoV-2 infection with peak virus production from apical wash at 48-72 h post infection (h pi) and remained at a high level from 3 to 6 days. As shown in Fig. 1c , virus particles were found on the apical surface of both ciliated cells and secretory cells; inclusion bodies formed by viral components were observed in the cytoplasm, which confirmed the infection of both cell types. ./cache/cord-343455-v1648kng.txt ./txt/cord-343455-v1648kng.txt
