They may represent what remains of the archegonium in angiosperms and the pollen tube may penetrate a synergid first, but they do not participate in the fertilization process and abort soon afterwards.

它们扮演了残留的被子植物藏卵器的角色。花粉管可首先穿透其中一个助细胞，但助细胞并不参与到受精过程中去，而且随后会消亡。

Results There was no apparent gender difference among 14 patients. 9 patients were younger than 30 years old. Pathological examination showed that bronchial infiltration of eosinophils in 14 patient (100%), thickened basement membrane of the bronchial mucosa in 12 patients (85.7%), proliferation of smooth muscle cells in 11 patients (78.6%), proliferative mucous gland in 9 patients (64.3%), mucous plug in bronchiole in 8 patients (57.1%), and cicatvization of left ventricle in 10 patients (71.4%).

Between parenchymal cells existed an intercellular canaliculus linking perivascular space.

实质细胞间存在与血管周隙相通的细胞间小管。

It plays a key role in the process of cell division, cell movement, pollen tube elongation and so on.

ADF蛋白是一种在真核生物中广泛存在的低分子量的肌动蛋白结合蛋白，在细胞分裂、细胞运动、花粉管伸长等重要的生命活动中发挥着重要的作用。

When the mice pre - sensitized were infected with RSV, the pulmonary inflammation, lymphocyte and eosinophils infiltration and cell - collar peribronchiles were more severe in lung organization and bronchiole than those in the single RSV infection group.

结果病理检查证实小鼠感染RSV后发展为典型的间质性肺炎；致敏小鼠感染RSV后病变更明显，细支气管周围淋巴细胞浸润形成管套增厚，嗜酸细胞增多，炎性细胞浸润的细支气管比例显著增高。

The Cork was consisted of five or six layer long cells. The secondary phloem occupied 46% of the diameter of root, and the parenchymas cell was abundant of the inclusions. The secondary xylem consisted of vessel, xylary radial ,and a little of xylary parenchyma cells. Some segment of hypha, swelled hypha, pelotons and conidiophore were colonied in cork and secondary phloem.

周皮由木栓层，木栓形成层和栓内层组成，其中木栓层由5～6 列长形细胞组成；维管组织中次生韧皮部所占根径的比例达46%，其薄壁细胞中内含物较丰富，次生木质部中分布有导管和木射线及少量木薄壁组织；在格木木栓层和次生韧皮部中分布有菌丝片段、膨大的菌丝和菌丝团及分生孢子。

In the present review, we focus on some of the recent advances and some key developmental events revealed in the fertilization process, including the role of the egg apparatus in guiding pollen tube orientation, sperm cell movement to their targeting cells, interaction between gametes, egg cell activation, and onset of embryogenesis and endosperm development.

本文着重讨论受精作用的若干重要发育事件，包括受精前卵器细胞对花粉管向胚珠定向生长的近距离引导信号，精子的靶向运动，精、卵细胞相互作用和配子融合后卵细胞的激活与中央细胞发育的启动等。

The process of EMT is induced in epithelial cells to lose its cell-to-cell adhesion and transform to mesenchymal-like cells.

同时，近端肾小管的纤维母细胞亦经类似 EMT 之机制而转变成纤维原母细胞，此也是造成肾病变的因素。

In the zygote and endosperm cells, sperm plastids can also be detected by their features.

杜鹃的成熟花粉是二细胞型，精细胞在花粉管中形成。

The series of changes in quantiative and spatial distribution of the three cytoskeleton elements throughout the maturation course of FVA cells was coincided with the process of nucleus eccentricity in position and denucleation, and all of the changes began at the early stage of erythroblast.

一。采用细胞免疫荧光组化方法系统地观察了微丝、微管和中间纤维骨架成分在红系细胞终末分化各阶段的动态变化。

And Pharaoh spoke to Joseph, saying, Your father and your brothers have come to you.

47：5 法老对约瑟说，你父亲和你弟兄们到你这里来了。

Additionally, the approximate flattening of surface strip using lines linking midpoints on perpendicular lines between geodesic curves and the unconditional extreme value method are discussed.

提出了用测地线方程、曲面上两点间短程线来计算膜结构曲面测地线的方法，同时，采用测地线间垂线的中点连线和用无约束极值法进行空间条状曲面近似展开的分析。
