    Hemocytes and granular cell fragments of Tipula paludosa larvae (1987)

    Notizen: Five morphological categories of hemocyte (prohemocyte, ameboid plasmatocyte, spindle-shaped plasmatocyte, oenocytoid, and granular cell) were observed by light and electron microscopy of hemolymph from Tipula paludosa larvae. In addition, vast numbers of membrane-bounded granule-containing fragments were present, and were also found in the larval hemolymph of four other Tipula spp. The fragments appear to be derived from the granular cells, which readily fragment. Granules in the granular cells and the fragments appear to have similar substructure. Melanization and coagulation of the hemolymph occur rapidly on exposure to air; the granular cell fragments may be concerned with one or both of these processes.

    The juxtaglomerular apparatus in fetal and newborn mice (1967)
    New York, NY [u.a.] : Wiley-Blackwell

    Notizen: Kidneys of timed fetal and newborn mice of the C57BL stock were sectioned and stained with a modified Bowie technique. The juxtaglomerular cells, indentifiable by their granularity and position, were recognized rather late in fetal life  -  three or four days before birth. By the eighth day postpartum, the granular cells of the JGA had reached a peak of differentiation and closely resembled the adult JGA in their number, size, granularity, and position. The mesangial cell was often but not always granulated. The granular cell indices (G.C.I.) of fetal, newborn, and adult mice are compared. The high G.C.I. in fetal kidneys in our studies should account for the high renin titre found by others in fetal kidney extracts.
