Therefore,people begin to attempt to inhibit nuclear maturation of oocytes,to improve oocyte quality.

因此，近年来人们开始探讨人工控制卵母细胞核成熟，以提高卵胞质成熟度。

According to the size and shape of cells,nuclei and nucleoli,and to the NPand the vitelline accumulation,the oogenesis can be divided into five phases:oogonium phase,small growth phase,large growth phase,pro- maturation phase and ma...

卵子发生根据卵细胞、细胞核及核仁的大小形态、核质比和卵黄积累情况可分为：1。卵原细胞期：2。小生长期；3。大生长期；4。成熟前期和5。成熟期。卵巢发育则根据第一批卵细胞的发育情况、卵巢长度及颜色分为五期，大致可归纳为三个阶段：5～7月为延缓期；8～11月为对数增长期：12～4月为稳定期。

Methods: The effects of Opuntia on proliferation of fibroblast were measured with MTT colorimetric assay, and PCNA productions were examined with immunocytechemistry.

以小鼠成纤维细胞株(NIH3T3)为研究对象，采用四氮唑盐比色法测定仙人掌对成纤维细胞增生的影响，采用免疫细胞化学染色法检测成纤维细胞的增殖细胞核抗原的表达。

The nucleus: information central the eukaryotic cell nucleus is the largest organelle and houses the genetic material on chromosomes.

中坚力量：信息中央 the 真核状态的细胞核是最大的细胞器并且安置在染色体的基因。

The eukaryotic cell nucleus is the largest organelle and houses the geneticmaterial on chromosome.

真核细胞的细胞核是细胞中最大的细胞器，在染色体上储存着遗传物质。

Objective:To explore the relationship between the expression of nuclear factor κB and angiogenesis in osteosarcoma.

目的：探讨细胞核因子κB表达与骨肉瘤血管生成的关系。

On magnification, all tumors have sharp peripheral circumscription and all tumors were confined to the upper dermis,and tumor continuity with the epidermis was noted in some cases.Some basloid aggregations associated with a palisaded alignment of the cells at the periphery of the aggregations can be seen..

镜下可见肿瘤边界清楚，大多位于真皮浅层，部分与表皮相连，可见多数基底样细胞集合，周边细胞核成栅栏样排列，绕以明显的纤维性基质以及纤维母细胞，有时在结缔组织之间可见裂隙。

Although the cloned child will carry the same problem genes as the parent who donates the nucleus, he or she will in all likelihood enjoy the parent's state of health and will be free of the additional risks caused by mixing both parents?genes during sexual reproduction.

尽管被克隆的孩子也会携带捐赠细胞核的父亲的问题基因，但是他们十有八九会享有和父亲一样的健康，并且在有性生殖的时候也会避免因为混合了父母的基因而造成的另外的危险。

Nucleus and cytoplasm can be seen in all the parenchymatous cells and pericycle cells of secondary structure.

4次生构造的薄壁细胞和中柱鞘细胞中可见细胞核和细胞质。

Pekinensis . IAA at concentration of 0.4-1. 0 mg/L in solid MS medium incited many adventitious roots on hypocotyl segments. The earliest anatomic changes were observed on cut surface of hypocotyl segments under optical microscope 24 hours after IAA treatment: cytoplasmic and nuclear density became higher in a few of parenchytmatous cells adjacent to phloem in tissue of pericycle, followed by cell divisions.

在生长素诱导24h后，可借助显微切片观察到下胚轴切面附近明显的解剖学变化：首先是中柱鞘内靠近韧皮部的薄壁细胞的细胞质与细胞核变浓，染色加深，部分细胞分裂；随后是分裂的细胞团增大，逐渐形成根原基并分化出根冠。
