The distribution of actin filaments was examined in the seminiferous epithelium of the Habu (Trimeresurus flavoviridis; snake), by transmission electron microscopy and fluorescence histochemistry. By transmission electron microscopy, actin filaments were clearly found only at the site between Sertoli cell and spermatid without a lattice-like structure. Fluorescence histochemistry showed a weak labelling of actin filaments in the seminiferous epithelium, whereas these findings seem to be common among reptiles, they are different from those in mammals. Additionally, the bundles of actin filaments adjacent to the plasma membrane of Sertoli cells, appeared in other reptiles, were not observed in the Habu.
通过透射电子显微镜和荧光组织化学方法，对蝮蛇（Trimeresurus flavoviridis；一种蛇）生精上皮中的肌动蛋白丝分布进行了研究。通过透射电子显微镜观察，仅在支持细胞和精子细胞之间的部位清晰地发现了肌动蛋白丝，且没有晶格状结构。荧光组织化学显示生精上皮中肌动蛋白丝的标记较弱，尽管这些发现似乎在爬行动物中很常见，但它们与哺乳动物中的情况不同。此外，在其他爬行动物中出现的、与支持细胞质膜相邻的肌动蛋白丝束，在蝮蛇中未观察到。
