(Fig. 1.8b) PAS stained kidney section (X 260), which shows a normal glomerulus cut through the hilus. The branching mesangial stalk is clearly seen (arrow-1). The capillaries are attached to the stalk, forming peripheral capillary loops (arrow-2). Podocyte (epthelial cell) of capillary membrane Bowman's capsule Epitheial cell of Bowman's capsule Glomerular filtrate in urinary space Basement membrane Mesangial cell Endothelial cell of capillary membrane Plasma in capillary (Fig. 1.8c) Diagrammatic representation of the cell types of the renal glomerulus
(Fig. 1.8d) Electron micrograph (X 18,000). Part of a glomerular capillary wall under higher magnification. Endothelial pores are visible in places. The basement membrane shows three layers: Lamina rara interna (LRI), lamina densa (LD), and Lamina rara externa (LRE). L= Capillary lumen, U= urinary space. 3. Mesangium is composed of special cells and matrix. It is located mainly at the hilum of the glomerulus, and extends between capillary loops. Its main function is to support the capillary tuft, also, it may have a phagocytic function and contractile function. Phagocytic property of the mesangium helps in clearing the glomerulus from any circulating immune complexes or antigens. The contractile function may help in modulating the renal blood flow and the capillary wall filtration surface. Juxta-glomerular apparatus: Juxta-glomerular apparatus is a specialized structure which is present at the hilum (vascular pole) of the glomerulus (Figure 1.7&1.8). It is composed of four groups of cells which contain granules in their cytoplasm (most probably renin). These cells are: 1. The macula densa cells which are modified cells in distal convoluted tubules.
