查询词典 epithelial cells

We got the result: Bufo Raddei Strauch Tadpole (1) Bufo Raddei Strauch Tadpole was capable of lens regeneration, which originated from the epithelial cells at iris dorsal margin by dipigmentation.(2) Dipigmentation of Bufo Raddei Strauch by two methods: one was licked up by amoebocyte, the other one was flowed from the pigment cells.(3) In the lens regeneration cells of Bufo Raddei Strauch profiles of the mitochondria became complicated ribosome manifold, and the endoplasmic reticulum was cisternal dilation. During the process of deferentiation of lens fiber the cell nucleolus became little and chromatin shrinked.(4)The crystalline electrophoresis of Bufo Raddei Strauch Tadpole lens regeneration showed that during lens regeneration P-crystalline was expressed earliest then was γ-crystalline and α-crystallin, this result is consistent with newt.

结果表明：花背蟾蜍蝌蚪(1)具有晶状体再生的能力，其晶状体的再生来源于虹膜背缘的上皮细胞；(2)虹膜背缘去色素是转分化的前提，主要有两种方式：一种也是最主要的方式是在晶状体被摘除后虹膜外侧产生巨噬细胞，巨噬细胞吞噬虹膜色素上皮细胞中的色素颗粒；另一种方式是虹膜色素上皮细胞自身释放色素颗粒；(3)电镜观察发现虹膜色素上皮细胞转分化过程中线粒体有明显变化，核糖体增多，粗面内质网增多，晶状体纤维分化过程中细胞核逐渐凝聚；(4)SDS-PAGE电泳发现，花背蟾蜍蝌蚪晶状体再生中相关蛋白表达顺序与有尾类蝾螈相似，蛋白表达顺序依次是β-晶状体蛋白、γ-晶状体蛋白和α-晶状体蛋白，并且后两种蛋白几乎同时表达。

Objective: To investigate, 1 whether the body fluid of Ascaris lumbricoides could induce apoptosis of human alveolar epithelial cells (A549 cells) in vitro, and if there would be a possible relationship of ABF concentration or inducing time with the extent of apoptosis; 2 if the expression of bcl-2/bax would involve in and how it changes during the inducement of the apoptosis of A549 cells.

目的：用人蛔虫体腔液(Ascaris body fluid，简称ABF)体外诱导人肺上皮细胞株(A549)，观察其是否能够诱导靶细胞凋亡及凋亡与ABF浓度和作用时间的相互关系；运用RT-PCR方法检测靶细胞诱导过程中bcl-2／bax基因的表达变化，探讨其凋亡与基因表达的相互关系。

There was no significant difference in epithelial destruction, intra-luminal obstruction and BO formation between allografts from HO-1 transgenic pigs or non-transgenic pigs. However, in day 28 and 56 allografts, we did see some of the grafts still showed bronchiole structure with normal epithelial cells which hasn'tbeen found before.

The liver oval cell line WB-F344 derives from adult normal Fisher 344 male rats. It's a kind of liver infantine epithelial cells and has characteristics of liver stem cells. Many studies in vitro and in vivo imply that it has the role as precursor cells of hepatocacinoma, which indicates its function in hepatocarcinogenesis.

肝卵圆细胞株WB-F344来自正常成年同基因Fisher344雄性大鼠，是一种肝脏幼稚上皮细胞，具有肝脏干细胞的性质，体内、外的许多研究表明，它与肝癌的发生有一定的关系，具有肝癌前体细胞的作用。

Two new studies, one published inScience, showed how adult human epithelial cells could bereprogrammed, through the virally mediated introduction of justfour genes, to behave like pluripotent cells; that is, able to actas embryonic stem cells do, to produce every descendent cell type.

这几天头条连续推荐的是"号外：日本人的新里程碑梦没了"，徐荣祥声称他的声明让《自然》和《科学》杂志评出了2007年度十大科学进展，没有将日本的iPS细胞（即日美科学家将体细胞转变成了干细胞）列入。

Ransforming growth factor beta TGF-β is a potent growth suppressor of normal epithelial cells. However, many types of invasive cancer cells (e.g. breast cancer frequently overproduce TGF-β to enhance their growth and metastasis. Quite frequently, these cells do not possess a functional type II TGF-β receptor, indicating an aberrant TGF-β signaling is responsible for promoting cell growth.

Transforming growth factor beta 对於正常的上皮细胞是一个很强的生长抑制因子，然而，许多种具有蔓延侵犯性的癌细胞常常是表现大量的 TGF-β来促进细胞生长与转移，这些癌细胞通常不表现具有功能性的第二型 TGF-β receptor，显示有另类的 TGF-β讯息传递可以促进细胞生长。

The epithelial openings were observed on and among epithelial cells facing the subarachnoid space.The subepithelial connective tissue penetrated the pineal body forming interlobular septum,and separated the pineal body to parenchymal lobules.
