Co-culture of transduced A549 cells and transduced 293T cells induced syncytia formation. A Representative images of cell–cell fusion in co-culture of either S-WT-293T or S-Δ19-293T with hACE2-A549 cells using EVOS FL color image systems. B Representative images of cell–cell fusion events in co-culture of either S-WT-A549 or S-Δ19-A549 with hACE2-293T cells. C Images of cell–cell fusion in co-culture of either S-WT-A549 or S-Δ19-A549 with hACE2-A549 cells. Scale bar equals 400 µm
