We conclude that UCMSCs, with a newly demonstrated endodermic differentiation potential, might be an alternative source for liver-directed cell therapies.

UCMSCs新近被证实具有内胚层分化的潜能，可作为肝细胞基因治疗的一个可供选择的来源。

The cytogenetic toxic effects of different concentration of As2O3 within different time on the cell of Vicia Faba root tip were studied.

本文以蚕豆根尖为材料，研究不同浓度As2O3在不同的处理时间内对蚕豆胚根根尖的细胞遗传学毒性效应。

This pushing-in of cells marks the start of gastrulation.

细胞的这种向里推进标志着原肠胚形成的开始。

RT-PCR results showed that GDF8/11 gene was expressed in new fertilized cell, early gastrulation and knife-shaped embryo, which was different from that in mammals.

RT-PCR结果表明GDF8/11基因在新受精的细胞、早原肠胚和刀形胚胎中表达，这与哺乳动物中的情况不同。

Up to the stage called gastrulation, the cell aggregate may be divided artificially in two, and each remaining half will develop into a well-shaped individual.

直到原肠胚形成的阶段，细胞集合体也许人工地被划分成二个，并且各剩下的一半将显现出完整形状的个体。

Using chicken eggs and a state-of-the-art imaging device which can reveal how cells move in three dimensions, the researchers demonstrated a key difference in the way gastrulation occurs between higher vertebrate species and less evolutionarily advanced animals.

利用鸡卵和能反应细胞三维移动的最新成像设备，科学家证明了高等脊椎动物和低等动物之间原肠胚形成的差异。

This site provides image materials on fish development, including time-lapse recordings illustrate the morphogenesis of zebrafish embryos, from early cleavage to organ rudiment formation, fish epidermal cell movies, 3-D films of zebrafish gastrulation, and much more.

该网站提供有关鱼类发育的图像材料，包括阐明斑马鱼胚胎形态发生（从早期卵裂到器官初期形成）的时间间隔录象、鱼类表皮细胞影片、斑马鱼原肠胚形成的三维影片，等等。

The cause of hindering the gynospore formation was short of boronin chestnut orchard,which led to the poor pollination and a decrease ofendogenous GA1/3, iPAs level and an increase of endogenous ABA level in ovary,which restrained the mother cell division of gynospore.The low level ofendogenous GA1/3,iPAs contents and the increase of endogenous ABA contentcaused a serious lack of reducing sugar,starch,protein and potassium in ovary,which led to a cease of young embryo development.

其中，大孢子形成过程的停滞是由于栗园B素缺乏，致使授粉不良和子房内源GA1/3、iPAS等含量下降，ABA含量上升，从而抑制大孢子母细胞分裂；幼胚发育停滞则是由于子房内源GA1/3、iPAS等生长类激素的上升启动受阻，继续处于低水平，ABA上升，使子房中还原糖、淀粉、蛋白质和K素积累受阻，造成营养严重缺乏。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
