    InvivoGen ace2 over expressing a549 cells
    Comparative fitness of EG.5.1 and XBB.1.9.1 (A) Beta-galactosidase staining on differentiated nasal organoid monolayers from a younger adult (28 years old) and an older adult (68 years old). Upper panel: light microscopy; Lower panel: Nuclei were counterstained with DAPI (blue). Scale bar, 100 μm (left), 50 μm (right). (B) Viral replication in <t>VeroE6/TMPRSS2</t> cell line, <t>A549/TMPRSS2/ACE2</t> cell line or nasal organoids derived from the younger adult or the older adult. The viral load was determined using RT-qPCR. Data represent mean, and error bar represents one standard deviation. The viral load at each time point was compared using Student’s t test. ∗, p < 0.05. (C) Competition assay between EG.5.1 and XBB.1.9.1. Human nasal organoid derived from the young adult was infected with EG.5.1 and XBB.1.9.1 at a EG.5.1:XBB.1.9.1 TCID 50 ratio of 1:1. Next generation sequencing was performed on the cell culture supernatants that were collected at 24, 48 and 72 hpi. The percentage of reads corresponding to the EG.5.1 was determined using the spike amino acid residues 52 and 456. The data at 0 h time point represents the sequencing result of the 1:1 mixture. Data represent mean, and error bar represents one standard deviation.
