This image depicts human HEK293 cells, which express the SARS-CoV-2 protein ORF7A and which have been tagged with green fluorescent protein (GFP). This tag allows us to visualize where the protein is in a given cell and allows us to assess which cells produce the protein. DAPI was used to stain nuclei blue to contrast the green viral protein. These cells were part of an experiment designed to understand how SARS-CoV-2 impacts epigenetic regulation.
