Cytochalasin B (CB) exerts an inhibiting effect on the formation, migration and anchoring in the cortex of the meiotic spindle in maturing Xenopus laevis oocytes. Regional sensitivity to CB (CB-sensitive zones) has been found in the oocytes which varies with reference to the stage of oocyte maturation at which CB is applied. Light and electron microscopy has shown that in these CB-sensitive zones the yolk and pigment granules, unlike the cortical ones, are displaced into the cytoplasm centripetally under the influence of CB.
细胞松弛素B(CB)对非洲爪蟾成熟卵母细胞减数分裂纺锤体在皮质中的形成、迁移和锚定具有抑制作用。在卵母细胞中发现了对CB的区域敏感性(CB敏感区),其随施加CB时卵母细胞成熟阶段的不同而变化。光学显微镜和电子显微镜显示,在这些CB敏感区,卵黄和色素颗粒与皮质颗粒不同,在CB的影响下向心移位到细胞质中。
