Fusion of SARS-CoV-2 infected host cells. Infected cells form submillimeter clusters of multiple fused cells at 24Â h post-infection. HeIM highlights the continuity of their membranes, while fluorescence microscopy shows the presence of multiple DAPI stained fluorescent nuclei (blue in M) in clusters of cells imaged with phase-contrast microscopy (PC).
