The ordered columnar structure of mouse filiform papillae.

Examination of carefully oriented 1-mum and 5-mum sections of mouse dorsal tongue together with scanning electron microscope observations indicates a high degree of cellular organization in the papillae. It has been suggested that each filiform papilla consists of 2 dominant and 2 minor columns of cells. Labelling patterns of the basal cells have been investigated in relation to these columns.
