Caption

(A) en-face view of ACE2 protein signal in human nasal respiratory, nasopharynx transitional, and oral squamous epitheliums. Scale bars, 50 μm. (B) Cross-sectional view of human nasal epithelium showing robust ACE2 protein in acetylated-?-tubulin+ ciliated epithelium (yellow arrowheads). Box region of upper panel is highlighted in lower panels. Scale bars, 50 μm. Profile analysis of relative ACE2 signal intensity along the white line. Note that ACE2 protein is higher in apical side than basal side, while it is not present at motile cilia.
