The kidney's glomerular filtration barrier consists of two cellsâpodocytes and endothelial cellsâand the glomerular basement membrane (GBM), a specialized extracellular matrix that lies between them.he glomerular basement membrane (GBM) is the extracellular matrix component of the selectively permeable glomerular filtration barrier (GFB) that separates the vasculature from the urinary space.
Cell membranes are primarily composed of a phospholipid bilayer. Amongst these layers there are proteins embedded both on the inner and outer surfaces and through the layer ofâ¦ten acting as channels for other substances.    The outer surface of the membrane contains carbohydrate chains attached to surface proteins.
