Figure Lengend Snippet: Vital imaging can define areas of neuronal OE regeneration after lesioning (A) Whole mount staining of the nasal cavity from a methimazole/dichlobenil lesioned mouse using PGP 9.5/TUBB4 identifies areas on both the lateral wall and septum where respiratory metaplasia (arrowheads) in previous neuronal OE. D = dorsal, V = ventral, A = anterior, p = posterior, OB = olfactory bulb. Scale bars = 2 mm. (B) A coronal section of the nasal cavity from a methimazole/dichlobenil lesioned mouse demonstrates respiratory metaplasia in the dorsal area of OE (arrows). The arrowhead indicates intracavitary excrescences from the injured OE. Scale bar = 1 mm. (C) Regenerated ventral OE from the boxed area labeled “C” in Figure 5 B contains a thick layer of TUJ1 labeled OSNs without TUBB4+ cells. Scale bar = 25 μm. (D) A dorsal region of OE from the boxed area labeled “D” in Figure 5 B is without neurons and is labeled for respiratory cells with TUBB4 antibodies. Scale bar = 25 μm.
