hACE2 is seen in hACE2+ fetal mouse brains at both time points. (A) Allen brain atlas images of E15.5 and E18.5 fetal brains showing regions imaged for IHC (blue box). (B) hACE2 is detected in imaged regions of both E14.5 and E18.5 hACE2+ fetal brains. (C) Imaging flow cytometry of hACE2 expression in DAPI+ cells of mock-infected and infected fetal brains. (D) Imaging flow cytometry of S protein detection in hACE2+ cells. n = 4. (E) Representative images from imaging flow cytometry.
