Mucous non-goblet cells in the small intestine of guinea pigs (Cavia porcellus) : a histological and histochemical study
BACKGROUND: The covering and glandular epithelium of the small intestine in guinea pigs (Cavia porcellus) include some mucus-secreting cells. Goblet cells are specific cells for mucus secretion with a distinctive cup-like appearance due to the accumulation of mucin in the apical pole. The deep crypt secretory (DCS) cells were identified in a limited array of species and only recently were noticed in the large intestine in mice, guinea pigs, humans, monkeys, and pigs. Our study focuses on the microscopical and histochemical features of the DCS cells in the small intestine of guinea pigs.
MATERIALS AND METHODS: The samples from the small intestine were collected from five fully grown guinea pigs that were presented to the Hospital of the Faculty of Veterinary Medicine Cluj-Napoca (Romania) with severe lesions resulted from domestic activities. The collected tissue samples underwent fixation in 10% buffered formalin and were later processed by standard paraffin technique. Mucous substances were detected using the Periodic Acid-Schiff and Alcian-Blue histochemical stain methods.
RESULTS: The intestinal samples of the guinea pigs assessed had a standard microanatomical structure. As regards the mucous-secreting cells from the small intestine, two cell types were identified, i.e. the goblet cells and DCS cells. DCS cells were only detected in the deep parts of the Lieberkühn glands from the jejunum and ileum, and were different morphologically and histochemically from the regular goblet cells.
CONCLUSIONS: Our study managed to describe for the first time in guinea pigs, the existence of DCS cells in the jejunum and ileum of the small intestine, but not in the duodenum.
