    Postnatal differentiation of ventricular myocardial cells of the opossum (Didelphis virginiana Kerr) and T-tubule formation (1980)

    Notes: Summary Cardiac muscle cells in the right ventricle of the postnatal opposum were studied ultrastructurally, with particular attention to the developmental stage of T-tubule formation. Animals ranging from 5.5cm (day 29 of postnatal life) to 41 cm (young adult) in body length were used. Typical T-tubules were first recognized in a few myocardial cells of the 7.5cm (day 43) opossum. T-tubules increased in number as cardiac muscle cells continued to differentiate until 22cm in body length (about 105 days after birth). At this stage of development most of the T-tubules were completely established. The general mode of differentiation and development of cardiac muscle cells appeared essentially the same as in other mammals.

    An immunohistochemical survey of endocrine cells and nerves in the proximal small intestine of the platypus, Ornithorhynchus anatinus (1983)
    Springer
    Cell & tissue research 234 (1983), S. 153-164 
    Details
    ISSN: 1432-0878
    Keywords: Immunohistochemistry ; Gastrointestinal endocrine cells ; Brain-gut peptides ; Small intestine ; Platypus

    Topics: Biology , Medicine
    Notes: Summary The relative frequencies of endocrine cells and peptidergic nerve elements in the proximal small intestine of the adult platypus were studied by immunohistochemistry. Six kinds of endocrine cells — serotonin (5-HT)-, somatostatin-, gastrin-, motilin-, cholecystokinin (CCK) and bovine pancreatic polypeptide (BPP)-immunoreactive cells — were identified in this study. These endocrine cells were found most frequently in the intestinal glands, in moderate numbers in the tubular ducts and were infrequent in the surface folds. 5-HT-immunoreactive cells were most numerous, somatostatin-, gastrin-, motilin and BPP-immunoreactive cells were moderately numerous, whereas CCK-immunoreactive cells were rare. Five kinds of neuropeptides: substance P, vasoactive intestinal polypeptide (VIP), gastrin releasing peptide (GRP), somatostatin and leuenkephalin, were detected in the intramural nerve elements. Substance P-, VIP and GRP-immunoreactive nerve fibers were found most frequently in the lamina propria mucosae of the surface folds. The relationships between the possible functions of the peptides and amine detected in this study as well as the characteristic structure of the digestive tract of the adult platypus are discussed.
