- Abstract
Granular ducts in the mandibular gland in rats present various types of cells. The secretion mechanism of these cells is different, thus we aimed to assess the secretory mechanisms present in cells lining the granular ducts in the mandibular glands in albino Wistar rat. The study was approved by the Bioethics Committee of University of Agricultural Sciences and Veterinary Medicine in Cluj-Napoca. We utilized 5 adult male albino Wistar rats, harvested the mandibular glands and processed them for histological examination. Upon examining the slides, we observed that most of the cells presented merocrine secretory mechanism, but some presented bulges in the apical pole with a tendency to strangle and detach as vesicles, signs of apocrine secretory mechanism. We also identified cells with discontinuities in the apical pole, with a tendency to eliminate all the cytoplasmic components. The aspect suggested the fact that these cells eliminate their secretion in a holocrine fashion. The morphological aspects suggest that the cells lining the granular ducts in albino Wistar rat mandibular gland present merocrine and apocrine secretory mechanisms. Besides, they also present holocrine secretory mechanism, the first time reported in this species.
