Journal of Cell Science

|October 1, 1976

Summary

Background:

Filiform papillae on the dorsal tongue exhibit complex cellular arrangements.
Previous models suggest a structure of dominant and minor cell columns within papillae.

Purpose of the Study:

To investigate the cellular organization of mouse dorsal tongue papillae.
To analyze basal cell labeling patterns in relation to proposed cellular columns.

Main Methods:

Examination of 1-mum and 5-mum sections of mouse dorsal tongue.
Scanning electron microscopy (SEM) observations.
Analysis of basal cell labeling patterns.

Main Results:

High degree of cellular organization observed in papillae.
Labeling patterns of basal cells were investigated.
Findings relate to the proposed dominant and minor cell column model.

Conclusions:

The study provides insights into the cellular architecture of filiform papillae.
Basal cell labeling supports or refutes the proposed columnar organization.
Further understanding of tongue tissue development and function.
