Because the signaling molecules RAS and ERK1/2 (extracellular signal–regulated kinases 1 and 2) are activated by an LH surge in granulosa cells of preovulatory follicles, we disrupted Erk1/2 in mouse granulosa cells and provide in vivo evidence that these kinases are necessary for LH-induced oocyte resumption of meiosis, ovulation, and luteinization.

研究人员仍然在试图解析接着发生的那些导致排卵（或在某些情况下没有排卵）的分子信号级联反应。研究人员现在证明，激酶ERK1和ERK2是该激素信号的至关重要的下游标靶。在那些颗粒细胞中缺乏这些酶的雌性小鼠中，其卵母细胞不会成熟，因而不会从它们的滤泡中释放出来。

RESULTS: There were many vacuoles and cracks in the cells, with heterochromatin margination, nuclear pycnosis and nuclear fragmentation. The high intensity pulsed electric fields caused damage in K562 cells, and the apoptotic percentage went up with the increase in frequency and intensity of PEF.

结果：经过高电压脉冲电场处理后的K562细胞，胞内出现大量空泡及裂隙，核内染色质向核周边聚集形成凋亡小体，呈典型细胞凋亡形态学改变；K562癌细胞的凋亡比例随着脉冲个数和电场强度的增加而增加。

In light and electronic microscopy, they appeared cell shrinkage, cell density increasing and eosinophilic, aggregation of cytoplasmic organelles, nucleolus fragmentation, and chromatin margination, condensation, and fragmentation. Those changes could be detected by TUNEL method.

在光镜和电镜下癌细胞凋亡表现为细胞体积缩小，胞浆浓缩嗜酸性，胞浆出泡、细胞器缩小或减少，核仁松解，染色质聚集、靠边、浓聚、断裂，在TUNEL法检测凋亡癌细胞时也可观察到相应的形态特点。

A network of stacked membranous vesicles present in most living cells that functions in the formation of secretions within the cell.

堆叠的膜泡网络，在大多数活细胞中存在，用以形成细胞内的各种分泌液。

MethodsBorneol contained serum was prepared and using Matin-Darby canine kidney epithelium cell line as the in vitro BBB model to observe the effects of borneol on intercellular tight junction and pinocytosis vesicles of BBB model.

方法制备含冰片的家兔血清，应用马丁达比狗肾上皮细胞系作为血脑屏障的体外模型，观察冰片对血脑屏障细胞间紧密连接、细胞吞饮囊泡的影响。

The nuclei were of low to intermediate nuclear grade with minimal nuclear pleomorphism. Thirteen of 17 cases (76%) were associated with conventional high-grade invasive urothelial carcinoma and 9 cases showed very focal intracytoplasmic vacuoles mimicking signet ring cells.

瘤细胞核的核级为低到中级，伴轻微的多形性。17例中有13例（76%）与常见的高度侵袭性的尿路上皮癌相关；有9例含灶性胞浆内空泡的瘤细胞，类似印戒细胞。

The morphology and number of lamellar bodies, perirhabdomal vacuole and pigment granule in the retinula changed with the day-night rhythm.

另外，在小网膜细胞中的板膜体、膜下储泡囊、色素颗粒等细胞器的形态和数量也随光周期呈现出规律性的变化。

The distribution of Na(superscript +) in intracellular and extracellular spaces in leaves of arrowleaf saltbush subjected to salt stresses was investigated by using a scanning electron microscope facilitated with an Auger electron spectrometer. The role of salt bladders in salt resistance of A. triangularis was analysed in terms of salt accumulation and secretion.

用扫描电镜和能谱仪测定不同浓度NaCl胁迫2 wk后的三角滨藜幼叶和成熟叶中Na在细胞外和细胞内的分布情况，并利用原子吸收分光光度计测定叶片中Na的积累量，同时还观测了盐囊泡及其与盐的积累、分泌之间的关系。

The distribution of Na^＋ in iutracellular and extracellular spaces in leaves of arrowleaf saltbush subjected to salt stresses was investigated by using a scanning electron microscope facilitated with an Auger electron spectrometer. The role of salt bladders in salt resistance ofA. triangularis was analysed in terms of salt accumulation and secretion.

The short intercalated duct and the long secretory duct have been found in the parotid gland,the long intercalated duct and secretory duct in submaxillary ...

腺泡的发育先于导管，粘液性腺细胞的发育先于浆液性腺细胞。并与大熊猫的唾液腺的组织结构进行了比较研究。
