A Striated Intercellular Material in Rat Brain

Nature volume 198, pages 701–703 (1963)Cite this article

Abstract

A UNIQUE intercellular material has been found beneath the subcommissural organ of brains of young adult albino rats of both sexes and of two strains. In general, the spaces around cerebral arterioles and venules are bounded by typical basement membrane and contain occasional fibrocytes, small bundles of collagen and macrophages. However, at the vascular poles of the cells of the subcommissural organ, a remarkable striated material frequently occupies the perivascular space and may also be seen intercellularly as much as 4–5µ from a vessel. The space around cerebral capillaries is ordinarily occupied solely by basement membrane, but in this very localized area the space may become widened. The basement membrane then splits into endothelial and parenchymal laminæ which contain between them the striated intercellular material.
