Time‒lapse microscopy of syncytial cell formation. (a) Early stages of syncytium formation in two parental Fcwf-4 cells transfected with the FCoV S-GFP vector. The initiation of fusion and syncytium formation are indicated by arrows. Images were presented at 30-min intervals. Scale bar: 100 μm. (b) Detachment of the syncytium. The syncytium shown in panel A detached from the culture well within 10 min (indicated by arrows in Panels 5 h 00 m to 5 h 10 m). Images were presented at 5-min intervals. Scale bar: 100 μm.
