Representative images of K562 cells transduced with S-WT-EGFP, S-Δ19-EGFP and hACE2-mCherry vectors. Expression of S-WT-EGFP (A), S Δ19-EGFP (B), or hACE2-mCherry (C) in K562 cells by high resolution confocal microscopy. Top row represents DIC images. Bottom row represents merged confocal image (DAPI, blue; S-WT-EGFP or S-Δ19-EGFP, green; hACE2-mCherry, red). D, E Images of cell–cell fusion in co-culture of either S-WT-K562 or S-Δ19-K562 with hACE2-K562 cells. Scale bar equals 40 µm
