Crystalline arrays of coated parallel tubules (CPT) were observed by electron microscopy within dilated cisternae of the rough endoplasmic reticulum of pleomorphic mononuclear cells in a human osteosarcoma. The wall of the peculiar intracisternal tubules consisted of an electron-dense thin membrane-like envelope which appeared to be composed of granular subunits. The electron-lucent tubular core together with the limiting envelope was approximately 15 nm in diameter. A coat of fuzzy material, approximately 10 nm thick, tightly surrounded the membrane-like wall of the tubules. Cross sections of accumulations of CPT showed the tubules to be arranged in a hexagonal crystalline array. The nature and significance of the intracisternal CPT are unknown.
在人骨肉瘤的多形单核细胞糙面内质网扩张的潴泡内，通过电子显微镜观察到了包被平行小管（CPT）的晶体阵列。这些特殊的潴泡内小管的壁由电子致密的薄膜样包膜组成，该包膜似乎由颗粒亚基构成。电子透亮的管状核心与界限包膜的直径约为15纳米。一层约10纳米厚的模糊物质紧密围绕着小管的膜样壁。CPT聚集体的横截面显示小管呈六边形晶体阵列排列。潴泡内CPT的性质和意义尚不清楚。
