We therefore establish a human lung-on-chip model for SARS-CoV-2 infections, and probe the viral growth kinetics, cellular localization and responses to a low dose infection using qRT-PCR, ELISA, RNAscope, immunofluorescence and confocal imaging (Fig. 1J) . Nevertheless, total RNA extracted from the apical and vascular channels of an infected LoC without macrophages at 1 dpi revealed >10 4 genomes in both epithelial and endothelial cells (Fig. 2C ) and genome copy numbers exceeded those for cellular housekeeping gene RNAseP (Fig. 2D ). Human iPSC-derived alveolar and airway epithelial cells can be cultured at air-liquid interface and express SARS-CoV-2 host factors ./cache/cord-336938-03366q9t.txt ./txt/cord-336938-03366q9t.txt
