  • Title: Follicular and reticular arrangements of medullary cells in the adrenal gland of Göttingen Miniature pigs.
    Author: Unsicker K.
    Journal: Z Mikrosk Anat Forsch; 1976; 90(5):852-60. PubMed ID: 1031518.
    Abstract:
    In the adrenal gland of Göttingen miniature pigs adrenaline- and noradrenaline-storing cells showed follicular and reticular arrangements, which were not observed in the domesticated form (German land race) of Sus scrofa. Chromaffin cells could contain vacuoles, which were sometimes connected with follicles and filled with a material indistinguishable from that in follicles. Coated and smooth vesicles with contents of various electron densities were particularly abundant around vacuoles and Golgi areas, which were often found to be closely associated. Chromaffin cells were unconspicious with respect to other ultrastructural details. A comparison was made between this mode of arrangement and that seen after intense stimulation of the adrenal medulla using insulin, reserpine, or vinblastine. The possible significance of this particular pattern of arrangement of chromaffin cells is discussed.
