Spike protein mediates cell fusion in transduced K562 and A549 cells. A, B Immunofluorescent images of hybrid or syncytial formation when co-culture S-WT-K562 or S-Δ19-K562 with hACE2-A549 cells were obtained by confocal microscope. C, D Immunofluorescent images of cell fusion when co-culture S-WT-A549 or S-Δ19-A549 with hACE2-K562 cells. Scale bar equals 40 µm
