    Notes: Summary The periphery of splenic lymphoid follicles, an area rich in reticulum fibers, contains presumptive interdigitating cells characterized by low electron density, scantiness of cytoplasmic organelles, abundant surface foldings and, sometimes, electrondense granules of unknown significance.

    Notes: Summary This study describes the postnatal development of the nonlymphoid cells with special reference to the fibroblastic reticulum cells (FRCs) and interdigitating cells (IDCs). The first lymphocytes of the neonatal lymph nodes are located in the developing deep cortex units (DCUs) identified by the Gomori's technique for reticulin fibres. Ultrastructural studies demonstrate that FRCs form the stroma of the DCUs. By light and electron microscopy, it is demonstrated that FRCs occupy the outer cortex in the following stages of development of the lymph nodes. Thus, FRCs form the stroma of the primary follicles and, later, are transformed in follicular dendritic cells (FDCs) of the germinal centres. Immature or pro-IDCs appear as migrating elements in the deep cortex of lymph nodes of the neonatal rats. The ultrastructure of the pro-IDCs resembles that of the mature IDCs but not that of the phagocytic cells. Pro-IDCs are transformed into mature IDCs whose cytoplasmic expansions contact lymphocytes via tight junctions. Some of these lymphocytes are likely apposed to FRCs of the DCUs. No cells containing Birbeck granules were found in the parenchyma of the lymph nodes during the postnatal development. The role of these nonlymphoid cells is discussed with respect to the immunologic function of mammalian lymph nodes.

    Ultrastructural study of interdigitating cells in the thymus of the spotless starling, Sturnus unicolor (1982)

    Notes: Summary Interdigitating cells (IDC) in the thymus of the spotless starling, Sturnus unicolor, were examined by electron microscopy. They occur principally in the thymic medulla and corticomedullary border. They possess an irregular nucleus and a perinuclear area of cytoplasm, containing most of the membranous organelles, surrounded by a peripheral electron-lucent zone. Clusters of smooth Golgi vesicles and complicated labyrinthine membrane-membrane contacts are the most characteristic cytological features. Birbeck granules are absent. Lymphocytes, plasma cells and even myoid cells can be found embedded in the cytoplasm. Immature elements, intermediate between epithelial-reticular cells and interdigitating cells, are tentatively identified as prointerdigitating cells. The functional significance of IDCs, and their phylogenetic significance in the vertebrate immune system, is discussed.
