Abstract

The tubular basement membrane (TBM) (i.e. tubular basal lamina) of rat kidney was shown to be a fine meshwork by electron microscopy after negative staining. Strands of the meshwork formed a regular three dimensional lattice work. The pores of the meshwork were polygonal. There were two main pore sizes: one approximately 30 A in diameter, the other 42--60 A. In view of our previous observation that glomerular and alveolar basement membranes were made up fine meshwork, it is quite possible that the basement membranes of other organs are also made up such fine meshwork.

摘要

经负染色后，通过电子显微镜观察发现，大鼠肾脏的肾小管基底膜（即肾小管基膜）呈精细的网状结构。该网状结构的丝形成规则的三维晶格结构。网状结构的孔隙呈多边形。有两种主要的孔径大小：一种直径约为30埃，另一种为42 - 60埃。鉴于我们之前观察到肾小球和肺泡基底膜由精细的网状结构组成，其他器官的基底膜很可能也由这种精细的网状结构组成。
