Kidney Glomerular Basement Membrane Histology. The network of capillaries the mesangium and the podocytes form the glomerular tuft. This tuft is contained in the bowman s capsule.
It is a fused basement membrane of the endothelial cells and podocytes and also offers some support to the glomerular capillaries. The collagen iv content of the lamina densa stabilizes the structures and sustains the blood pressure within the capillaries. The network of capillaries the mesangium and the podocytes form the glomerular tuft.
See scheme of the glomerulus link.
The glomerular basement membrane consists of lamina rara interna lamina densa and lamina rara externa. The membranous transformation seen in primary or secondary membranous gn is the reaction of the gbm to subepithelial deposits between gbm and the visceral epithelial cell. This is formed by a basement membrane and a flat epithelium. This tuft is contained in the bowman s capsule.
