Extended Data Figure 2. Haemotoxylin and eosin (H&E) staining and immunohistochemistry on SARS-CoV-2 challenged hamster tissues.

Extended Data Figure 2.

a, Hyperplasia of the pneumocytes detected on 7 dpi. b, Detection of CD3 positive cells (using rabbit anti-human CD3 polyclonal antibody) in the lungs on 5 dpi. c, Detection of SARS-CoV-2 N protein (red staining, using monoclonal antibody 4D11) and olfactory neurons (brown staining, using monoclonal antibody TuJ1) from the nasal turbinate on 5 dpi. d, Detection of olfactory neurons (using monoclonal antibody TuJ1) from the nasal turbinate of a mock infected hamster (N=1). e, Nasal epithelial cells from the nasal turbinate of a mock infected hamster (N=1) showed negative staining for TuJ1. f, Detection of olfactory neurons from nasal turbinate on 2 dpi. g, Detection of olfactory neurons from nasal turbinate on 7 dpi. h. Detection of olfactory neurons from nasal turbinate on 14 dpi. i, H&E staining of the brain tissue on 5 dpi. j, H&E staining of the heart on 5 dpi. k, H&E staining of the liver on 5 dpi. l, H&E staining of the kidney on 5 dpi. Hamsters were intra-nasally inoculated with PBS (mock infection, N=1) or with 8 × 104 TCID50 of SARS-CoV-2 (N=9) and the tissues were collected on 2 (N=3), 5 (N=3), 7 (N=3) dpi. H&E and immunohistochemistry with tissues from three animals showed similar results and the representative results were shown.
