Abstract

The intestinal cell types of the pulmonate gastropod Planorbarius corneus were studied using histochemical, immunocytochemical and ultrastructural procedures. Supporting cells, mucous cells and gland cells were observed in the intestine epithelium. The supporting cells seem to be involved in absorption process, showing endocytosis vesicles, evidence of lysosomal activity and storage of reserve materials. The presence of epithelial cells specialized in secretion indicates that digestive enzymes may be produced. Indeed, immunoreactive alpha-amylase molecules have been demonstrated. Some gland cells showed the ultrastructural features of invertebrate and vertebrate enteroendocrine cells and were also positive to vertebrate anti-insulin, anti-gastrin and anti-serotonin antibodies.
