From: Human ACE2 protein is a molecular switch controlling the mode of SARS-CoV-2 transmission
Progenies of SARS-CoV-2 are packaged in hACE2-containing vesicles. Super-resolution immunofluorescence images of mock control (a) and SARS-CoV-2-infected hACE2-A549 cells (MOI = 0.2, 24 hpi, b). Scale bar, 20 μm (a and b). c CLEM image from SARS-CoV-2-infected hACE2-A549 cells (MOI = 0.2, 24 hpi), which combined the immunofluorescence images and TEM images from the same sample. Arrowhead, single membrane; arrow, VLSs; scale bar, 500 nm
