FIG 3.

Imaging of NiV-B replication in human lung grafts from nonreconstituted mice. Shown is H&E (left) and NiV-B nucleoprotein antigen (brown signal) (right) staining of human lung graft sections from nonreconstituted mice at day 3 (a and e) and day 5 (b and f) postinfection. Similar staining was performed on mock-infected lung graft sections from nonreconstituted mice at day 3 (c and g) and day 5 (d and h) postinfection. Images are representative of virus spread across lung grafts from nonreconstituted mice (a, b, e, and f). Original magnification, ×5. Bars, 200 μm.
