title: Electron microscopic demonstration of meshwork structure in human and bovine glomerular basement membranes.
abstract: With the electron microscopic and the negative staining method, the glomerular basement membrane of human and bovine kidneys was shown to have a definite fine meshwork structure. The pores of the meshwork of bovine glomerular basement membrane appeared to be pentagonal or hexagonal in shape. Strands of the meshwork branched three-dimensionally and made up the whole basement membrane. The portion of the sgrand between two neighboring branches was presumed to be a structural unit of the basement membrane. Glomerular basement membrane in man showed a structure similar to that seen in cattle, although the pore size of the meshwork was smaller in man than in cattle.
