Intranuclear microtubules appear in chick embryo fibroblasts upon infection with Frog Virus 3 (FV 3). Both the diameter and the annular shape of the microtubule profiles, established from electron microscopic observations using a goniometer, suggest that they are identical to naturally occurring cytoplasmic microtubules. Furthermore, the use of vinblastine allowed demonstration of the tubulin composition of the intranuclear microtubules.
感染青蛙病毒3（FV 3）后，鸡胚成纤维细胞中会出现核内微管。通过使用测角仪进行电子显微镜观察所确定的微管轮廓的直径和环形形状，表明它们与天然存在的细胞质微管相同。此外，使用长春花碱能够证明核内微管的微管蛋白组成。
