Nose, Olfactory Epithelium - Hyperplasia, Basal Cell - Gallery

Image of hyperplasia, basal cell in the nose, olfactory epithelium from a male F344/N rat in a subchronic study
Nose, Olfactory epithelium - Hyperplasia, Basal cell in a male F344/N rat from a subchronic study. Proliferation of basal cells is present just above the basement membrane of the olfactory mucosa (arrow).
