Summary We performed transcriptomic profiling of cells derived from human pluripotent stem cells (PSCs) using our previously described distal lung directed differentiation protocol to generate alveolar type II epithelial-like cells (iAT2s). We used the SPC2 human iPSC line containing a SFTPC-tdTomato knock-in reporter. SFTPC-tdTomato+ iAT2s were sorted on day 41 and again on day 69 of differentiation. iAT2s were single-cell passaged in self-renewing 3D alveolosphere culture approximately every 2 weeks through day 194 of differentiation. On day 208, iAT2s were single-cell passaged onto Transwell inserts. Apical media was removed on day 210 to initiate air-liquid interface culture. On day 218, 6 replicate wells of iAT2s were exposed to SARS-CoV-2 in an apical inoculum and 3 replicate wells were exposed to mock. On day 219, three mock and three post-infection samples (1 dpi) were collected. Three additional post-infection samples (4 dpi) were collected on day 222. We find that SARS-CoV-2 infected iAT2s express a rapid global transcriptomic change characterized by a shift to an inflammatory phenotype, time-dependent epithelial interferon responses, and rapid loss of the mature lung alveolar epithelial program.
