Distribution of goblet cells in the rat nasal septum by use of quantitative histological technique.
In this quantitative, histological study, both goblet cell number and distribution of secretory granules in normal septal mucosa of rats were examined by computer-based color image analysis combined with a new, simple whole-mount method. Our new method has proved to be a very useful and highly accurate means of examination. The count and size of the mucous area of goblet cells decreased toward the antero-posterior direction with the exception of the apical region of the septum. The regional difference characteristic of the goblet cell is noteworthy. The results are assumed to be closely related to both flow direction of mucous blanket and distribution of nasal gland orifices. Goblet cells are assumed to be controlled by some regulatory factor of the secretory system and to play an important role in nasal physiological mechanism.
