条纹膜结构是200±20 A厚的膜。它们在正常和病理肾小球中都很常见，因为在340例肾活检中发现了221例。它们的外观根据截面的平面而变化：在横截面上，它们类似于一堆板或双纵向带。切线切面上呈网状。纹状膜结构位于基底膜、系膜基质或细胞外病理沉积，如淀粉样蛋白或“免疫”沉积。这些膜可能是双层的，来源不明。它们可能源于基底膜样物质或细胞外沉积物中细胞成分的局部或全部裂解。
Striated membranous structures are membranes 200 plus or minus 20 A thick. They are very common in both normal and pathologic human glomeruli, since they were found in 221 of 340 renal biopsies studied. Their appearance varies according to the plane of the section: on cross-section they resemble a pile of plates or double longitudinal bands. On tangential section they have an areolar appearance. Striated membranous structures are located in the basement membrane, mesangial matrix, or extracellular pathologic deposits such as amyloid or "immune" deposits. These membranes, probably double layered, are of unknown origin. They might derive from the focal or total lysis of cellular elements included within basement membrane-like material or extracellular deposits.
