有丝分裂的

Synchronous and asynchronous chromosome separation was seen, and it was more common that the lagging chromosomes formed anaphase bridges.

有丝分裂过程中染色体的分离同步或不同步，不同步分离中的滞后染色体形成后期桥的现象更为普遍。

We also confirmed in this paper that it is injected somatic cells but not broken cytoplasm formed multi blastomere through mitosis in the reconstructed embryos.

在本实验中还通过用DNA染料（Hoechst-33342）对核移植体进行染色的方法，对融合后成纤维细胞在核移植体内不同时间的运行及发育模式进行了观察，确认了是成纤维细胞经有丝分裂形成多个卵裂球而不是由于细胞质碎裂形成的两个或多个碎块。

In the early stages of megagametophyte development, mitosis proceeds without immediate cell wall formation.

在 megagametophyte 发展的早阶段中，有丝分裂没有立即的细胞壁形成的收入。

It turned out that hematopoietic stem cells be immortalized by constitutive Notch1 and Delta has the function as the mitogenic regulators of hematopoietic stem cells.

研究人员将活化形式Notch受体导入造血干细胞，使其获得了细胞因子依赖性的"永生"；另外，Notch的配体Delta、Jagged具有类有丝分裂因子作用，可保持造血干细胞的自我更新能力，促进其体外增殖。

At normal state, the separase hasn't activity because of its inhibitor securin. But during the transition from metaphase to anaphase, APC is activated and it discomposes the securin. Then the separse what is a protease has activity and it discompose cohesin. So the sister chromatids separate.

通常情况下分离酶受到保全素(securin/PTTG)的抑制而没有活性，当细胞从有丝分裂中期向后期转变时，APC(anaphase-promoting complex，后期促进复合体)被激活并裂解保全素，具有蛋白酶活性的分离酶裂解粘合姐妹染色单体的粘合素，姐妹染色单体分离。

All of the FGFs family are the mitogen,affecting the ectoderm,entoderm and the mesenchymal cells.

全部的FGFs都是广谱的有丝分裂原，作用于外胚层、内胚层和间充质来源的细胞。

Endomitosis and the ring -like chromosome were also observed during mitosis .

比较表型与染色体检测结果发现，原生质体再生植株的表型变异往往来源于其有丝分裂变异造成的染色体数目的变异。

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。

IGF2, which encodes a protein functioning as a fetal growth factor and a cell mitogen, is expressed only from paternally allele in most tissues but from both alleles in adult liver. H1 9, which acts as an RNA, is a gene of unknown function and expressed only from maternally allele.

IGF2编码的胰岛素样生长因子-2是一种胚胎生长因子及细胞有丝分裂原，在人体内大多数组织中特异地表达父系来源的等位基因，而母源等位基因处于印记状态。H19表达一种功能尚不清楚的RNA，其印记状态与IGF2相反，目前发现H19在正常组织内均为母源等位基因表达，父源等位基因印记。

Microtubules play important roles in many essential cell functions including mitosis, intracellular transport, positioning of membrane-bounded organelles, and cell shape.

微管在细胞的许多过程中发挥着重要作用，如有丝分裂、胞内运输、膜围细胞器的定位以及细胞形态保持等等。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。

Designed by French fashion house Herm è s, this elegant uniform was manufactured in our home, Hong Kong, and was the first without a hat.

由著名品牌 Herm è s 设计，这件高贵的制服是香港本土制造，是我们第一套不配帽子的制服。
