  • Title: [Endocrine cell of the cow colonic mucosa].
    Author: Kostiukevich SV.
    Journal: Morfologiia; 2003; 123(2):72-6. PubMed ID: 12891785.
    Abstract:
    The epithelium of colon mucosa of the adult cow was studied using the methods of light and electron microscopy to demonstrate the endocrine cells. Individual fluctuations of the endocrine cell content was noted as well as an increase in the total number of endocrine cells in the rectal epithelium, that was more pronounced tan in other vertebrates. Four types of endocrine cells were demonstrated: EC, L, D, D1. The variability of dimensions and shape of granules in EC-cells was found to be less tan in other vertebrate species. In some D1-cells the mucous granules were observed along with endocrine ones, thus indicating the presence of "mixed" exo-endocrine cells. Undifferentiated endocrine cells were also detected that were found at the bottom of the crypts. The features indicated above are the specific peculiarities of endocrine apparatus of the mucosal epithelium of cow colon.
