查询词典 cytoplasm

The long-term opening of mitochondria permeability transition pore results in the release of cytochrome C, apoptosis inducing factors, Ca2+ and other apoptosis factors into cytoplasm, which can destruct the whole cell structure and function by activating the main member of apoptosis protein family——caspase, or destroying the intranuclear chromoplasm independently, or affecting other protein relying on Ca2+, and finally lead to the formation of apoptotic body.

线粒体是真核生物能量和代谢的中心，也是细胞凋亡信号传导途径中起关键作用的细胞器，越来越多的研究表明，在凋亡信号的刺激下，线粒体发生膨胀，其外膜膜电位降低，外膜破裂后释放出膜间隙的诸多凋亡效应因子，在细胞凋亡中起着主开关的作用。

Tetraploid embryos could be produced by electrofusion at the stage of two-cell embryos, which could develop to blastocysts followed by fusion of cyto-plasm and nucleus and cleavage in vitro. During the fusion of cytoplasm, the DNA methylation levels of the fused embryos are as high as these of two-cell diploid embryos in vivo Then the embryos are rapidly demethylated when the nucleus begin to fuse, resulting in the lowest DNA methylation levels when the nucleus are fused completely. After that, the DNA methy-lation levels of the fused embryos are gradually increased until the morula stage. However, whereas an asymmetric distribu-tion of DNA methylation is established in vivo-derived blastocysts with a higher methylation level in the inner cell mass than that in the trophectoderm, we can not detect the asymmetric distribution in most in vitro-derived tetraploid blastocysts.

结果表明：利用电融合方法制备的小鼠四倍体胚胎在体外培养体系中经历细胞质融合、细胞核融合及细胞继续分裂发育直到囊胚期的过程，在细胞质融合的时候胚胎卵裂球同体内体外培养二倍体胚胎一样，呈现高度甲基化状态；在细胞核开始融合的时候，甲基化水平急速下降，在细胞核完全融合的时候甲基化水平达到最低点；随着胚胎继续分裂，胚胎甲基化水平逐渐增加，在桑葚胚期甲基化水平最高；但是囊胚期四倍体胚胎内细胞团同滋养层细胞甲基化荧光信号没有差别，这与体内体外培养二倍体囊胚内细胞团细胞甲基化荧光强度高于滋养层细胞甲基化荧光强度不同。

Coenocyte An area of cytoplasm containing many nuclei and enclosed by a cell wall, typically found in many fungi, certain green algaee.g.

多核细胞，多核体：一定区域的细胞质中包含许多细胞核，由细胞壁包围的生物体。

The ultrastructural changes during the development of sieve element companion cell complex (SE/CC complex) in Populus deltoides were investigated using electronic microscopy. The result showed that SE and CC tome from the same secondary phloem mother cell. The development of sieve element went through three stages, i. e. immature, mature, and degenerate stage. In immature stages the sieve element presented radial expansion, cell wall thickening, and production of sieve plastid and P-protein. The cytoplasma selectivly autolysed in mature stage. At the same time, karyoplasm was dispersed, and nuclear envelope was not clear, or karyoplasm was disorgnized, and nuclear envelope was clear. The karyopalsm finally turned into P-protein. In degenerate stage, the cytoplasm completely disappeared, and the function was lost.

利用电镜技术研究美洲黑杨次生韧皮部筛管和伴胞发育过程中细胞超微结构的动态变化，观察到筛管和伴胞由同一个次生韧皮部衍生细胞分裂分化形成筛管约发育历经未成熟期、成熟期和衰退期的变化未成熟期筛管分子表现为细胞的径向扩展、壁的增厚、筛管质体和P-蛋白质的产生；成熟期筛管分子细胞组分发生选择性自溶，细胞核核质弥散状，核膜不清晰，或核膜清晰而核物质降解，最后细胞核完全解体转化为P-蛋白质类的物质；衰退期筛管分子细胞质完全解体消失，失去功能。

During the PCD, condensation of nucleus, marginalization of chromatin, nuclear membrane shrinkage and destruction apparently occurred, and many vesicles appeared in the cytoplasm, which may be related to the degradation of cell substances.

正在凋亡的细胞核染色质固缩、趋边、核膜破裂或皱缩、细胞质囊泡化并将降解的物质运到周围细胞，从而保证了其它细胞正常发育以及生长的细胞对物质和能量的需求。

The histological structure shows the lobule testis in Leptobotia elongate Bleeker, and the spermatogenesis is divided into 6 phases based on the size, nucleolus number, the degree of nucleus and cytoplasm condensation.

组织学结构显示长薄鳅的精巢属于小叶型，根据发育过程中细胞的大小、核仁多少、细胞核和细胞质浓缩的程度将精子发生划分为6个时相。

During spermiogenesis, the most dramatic morphological changes involve formation of the head and the flagellum, condensation of the nucleus, formation of the acrosome, and elimination of excess cytoplasm as the residual body.

成熟精子的顶体位于精子头部，内含有多种水解酶，在精子成熟、获能和受精过程中起着重要作用，因此研究顶体形成为探索控制生育和不育的机理提供了重要线索。

Main ultrastructrual changes included cytoplasm degeneration, want of pinocytotic vesicle and phagosone, decreased organelles and granules, mitochondria swelling, nucleus condensation, etc.

主要包括：中性粒细胞质变性，吞噬泡欠缺，细胞器及细胞颗粒减少，线粒体肿胀，细胞核浓缩等。

A549 cells are more sensitive to CDDP-induced apoptosis(P.01) and less sensitive to THP andβ-Ele-induced apoptosis than A375p(P.01, P.05 respectively). Condensation and crack of nucleus and apoptotic bodies appeared in apoptotic cells of A549 and A375p cell lines in all treated groups and necrocytosis were to be seen in some groups. Fluorescence imaging experiments demonstrated that accumulation of iASPP in cytoplasm but little distribution in nucleus in all groups. untreated groups in two cell lines presented a bright-green colour,followed by CDDP-treated groups,and THP-treated groups is the darkest one in all groups.

免疫荧光显示，未加药物处理的A549和A375p细胞胞质染色均匀呈亮绿色，核区较暗；CDDP及β-Ele处理组细胞为暗绿色，其中可见皱缩的凋亡细胞；THP处理的细胞胞质荧光弱呈灰绿色，由于THP嵌入DNA自发红色荧光与二抗的绿色荧光中和，胞核被染成桔红色，结果提示药物处理后A549和A375p细胞中iASPP的表达有不同程度的下降。
