(A, B) Growth curves for SARS-CoV-2 replication in 2D fetal intestinal monolayer model and 3D enteroid model, respectively. Viral RNA was measured by RT-qPCR analysis of the E gene in the culture medium collected at different time points. (C) Immunofluorescent staining of SARS-CoV-2 infected monolayer 24 hours postinfection. SARS-CoV-2 (yellow) infects enterocytes (purple, stained for villin). Scale bars, 100 μm. Data information: In (A, B), data are presented as geometric mean ± SEM.
