细胞分裂

As a matter of fact, tumor is a disease that is caused by being out of control of cell cycle.

肿瘤的生成实质上是细胞无限制地生长和分裂，是细胞周期调节的失控。

Objective To explore the relation between the biochemical stimulus and big deformation during cytokinesis in eukaryotes.

目的 探究真核细胞在有丝分裂过程中，生化刺激与细胞大变形行为之间的关系。

In meiosis of one hybrid between hexaploidⅢand O.violaceus, no chromosomepairing was found at diakinesis.

随后这些染色体随机的分向两极，但是细胞质并不分裂，导致双核细胞的形成，双核细胞停止了进一步的发育。

At diakinesis, 0.2 tetravalents, 0.05 hexavalents and 0.05 octovalents per pollen mother cell were detected, which was absent in cultivated cucumber. In 30% PMCs, crossed chromosomes occurred at diakinesis.

在减数分裂终变期，平均每个花粉母细胞有0.2个四价体、0.05个六价体和0.05个八价体，约30%的花粉母细胞中存在拉十字的染色体。

In Peiai 64S, the microtubules showed abnormal patterns of distribution from pre_meiotic interphase to metaphase Ⅰ. For example the broad band of perinuclear microtubules seen at diakinesis in IR36 was much disorganized and loosened in Peiai 64S.

(1)在偶线期具极性分布的微管分布不存在；(2 )在小孢子母细胞减数分裂期间的细胞内出现许多特别粗的微管束；(3)在终变期围绕核的微管宽带结构松散及内含微管密度低。

According to the number and behavior of B genomechromosomes, all hybrid plants were classified into three types. All somatic cells of TypesⅠplants contained 16 B genome chromosomes which formed 8Ⅱat diakinesis and shown8:8 segregation at anaphase; TypesⅡcontained 14 B genome chromosomes whichformed 6Ⅱ+2Ⅰat diakinesis and showed 6:8 or 7:7 segregation at anaphase. TypesⅢcontained above two chromosomes number and behavior.

同时根据B基因组DNA为探针的GISH结果，以细胞中B基因组染色体的数目及减数分裂时的配对及分离的方式，将所有杂种植株分为三大类：Ⅰ类具有16条B基因组染色体，以8Ⅱ的方式配对，以8：8分离，共32株；Ⅱ类具有14条B基因组染色体，以6Ⅱ+2Ⅰ方式配对，以7：7或者6：8的方式分离，共4株：Ⅲ类植株包含有上述两种细胞类型类型，共1株。

ResultsAll dividing stages （leptotene, zygotene, pachytene, diplotene stages and diakinesis） were observed in low power lens and those divi- ding stages increased greatly compared with the routine method.

结果 低倍镜下可见细线期、偶线期、粗线期、双线期、终变期细胞，各期细胞染色体分裂相较常规制片明显增加。

Although the oocytes collected from ovaries before IVM are usually arrested at the diplotene stage, they are different in developmental competence.

用于IVM的卵母细胞虽然都停滞在第一次减数分裂的双线期，但质量是不同的，造成卵母细胞体外成熟结果有很大差异。

The enteropathy shown here has loss of crypts, increased mitotic activity, loss of brush border, and infiltration with lymphocytes and plasma cells (B-cells sensitized to gliaden ).

肠下垂显示肠壁变薄，核分裂像增多，刷状缘减少，淋巴细胞和浆细胞浸润增多（ B 细胞对麸质较为敏感）。

The erasion of the mark likely was crucial in the process of the genome epigenetic reprogramming.

总之，TBP在有丝分裂中期染色体上的残留可能是分化细胞特有的细胞记忆标记；这一标记在核质重组胚的核重序过程中被去除。
