WebJan 17, 2012 · The renal filtration barrier, located within the glomerulus of the nephron, consists of three layers that must be traversed to enter the urinary space. These three layers are the glomerular endothelial fenestrations (≈100 nm) ( 14 ), the glomerular basement membrane (GBM), a 300-nm-thick connective tissue membrane rich in heparan sulfate ( …
The glomerular capillary endothelium has many perforations called fenestrae,which are pores about 70nm in diameter. These pores actually do not restrict the movement of water and proteins or large molecules but instead prevent the filtration of blood cells (e.g. RBCs). Surrounding the luminal surface of the … See more The basement membrane surrounds the capillary endothelium and is mostly made up of type IV collagen, heparan sulfate proteoglycans and laminin. In particular, heparan sulfate proteoglycans help restrict the movement of … See more Podocytesare specialised epithelial cells of Bowman’s capsule which form the visceral layer of the capsule.
