本研究跟踪的形态外观,组织,和消失的细胞骨架机械细胞分裂在第四个细胞周期的孤立海胆卵裂球的微管蛋白和肌球蛋白的免疫定位。中粒-中粒(平均分裂)和大粒-小粒(不平均分裂)在它们的星状体(有丝分裂和所谓的间期星状体)、纺锤体和收缩环方面进行了比较。这些结果表明,这些卵裂球的独特的核定位是在间期晚期建立的,中心体排列发生在前期,细胞周期中所有占主导地位的星形构型都属于一个单一的组装-拆卸周期,第二个间期特异性的组装-拆卸周期局限于弥散的细胞质网状结构,收缩环肌球蛋白的集中和分散与卵裂沟的开始和结束精确地一致。
This study traces the morphological appearance, organization, and disappearance of the cytoskeletal machinery for cell division during the fourth cell cycle of isolated sea urchin blastomeres by immunolocalization of tubulin and myosin. Mesomere-mesomeres (which divide equally) and macromere-micromeres (which divide unequally) are compared in terms of their asters (both mitotic and so-called interphase asters), spindle apparatus, and contractile ring. The results suggest that the distinctive nuclear positioning of these blastomeres is established in late interphase, that centrosomal alignment occurs in prophase, that all of the dominant astral configurations in the cell cycle belong to a single cycle of assembly-disassembly, that a second interphase-specific cycle of assembly-disassembly is confined to a diffuse cytoplasmic reticulum, and that contractile ring myosin concentrates and disperses in precise coincidence with the beginning and end of cleavage furrowing.
