Actin-containing filaments have been visualized inside the Xenopus oocyte nuclei due to combination of fluorescence and transmission electron microscopy. It has been shown that these filaments contact with nucleoli, spherical bodies and nuclear pore complexes. The incubation of oocytes with actin-depolymerizing latrunculin causes membrane vesiculation in the cytoplasm, and disruption of the nucleoplasm and nuclear envelope integrity. We suppose that actin-containing filaments belong to crucial cell components which are involved in coordination of nuclear-cytoplasmic interactions as well as distribution and transport of intranuclear components in growing Xenopus oocytes.
由于荧光显微镜和透射电子显微镜的联合使用，在非洲爪蟾卵母细胞核内已观察到含肌动蛋白的细丝。研究表明，这些细丝与核仁、球体和核孔复合体接触。用肌动蛋白解聚剂拉春库林处理卵母细胞会导致细胞质中出现膜泡化，并破坏核质和核膜的完整性。我们推测，含肌动蛋白的细丝属于关键的细胞成分，参与非洲爪蟾生长中的卵母细胞核质相互作用的协调以及核内成分的分布和运输。
