Figure 6.

Characterization of ACE2 expression in the human (Caco-2 and Huh-7) and Vero cell lines, at various time points after infection with MOI 1, by ICC ((A) microscopic images with 100 µm scale bar, including zooms of the red inserts; (B) heat map), Western blot (C), and qRT-PCR (D). In the graphs, data represent means ± SD of three independent experiments, and significant Student’s t-test p-values are indicated (** < 0.01). The ACE2 was placed in the membrane of all the infected cell lines.
