Figure EV3. Expression of IFITM1, IFITM2, and IFITM3 in SARS‐CoV‐2‐infected syncytia.

SARS‐CoV‐2‐induced syncytia in U2OS cells are IFITM1 dim or negative, but IFITM2/3 positive. Left: Non‐infected U2OS‐ACE2 cells. Middle and right: Cells infected with SARS‐CoV‐2 at the indicated MOI. The GFP area is delimited in white. With IFITM1, the fused GFP area does not overlap with the red IFITM1 area. For IFITM2 and IFITM3, an overlap with the GFP is visible. Scale bars: 100 µm. Quantifications are presented Fig 2C.
