胚细胞

ESCs are traditionally regarded as ICM cells, though some scholars believe they are more closely resemble cells from the epiblast. But recent evidence about cell molecular markers indicate that ES cell's characteristics resemble early germ cells.

传统观念常常把ESCs等同于ICM细胞，也有学者认为ESCs更象上胚层细胞，而在已知的分子标记基因方面，ESCs所具有的特征更接近体内早期生殖细胞。

We hypothesized that Notch signaling might play an important role in specifying endothelial progenitors from the mesoderm, given that this pathway acts as a bipotential cell-fate switch on equipotent progenitor populations in other settings.

由于在其他系统中的研究表明，Notch信号通路在同一潜能的前体细胞走向两种不同命运的过程中发挥着关键的转换作用，我们假定该通路在中胚层特化为内皮前体细胞的过程中也发挥重要功能。

The erasion of the mark likely was crucial in the process of the genome epigenetic reprogramming.

总之，TBP在有丝分裂中期染色体上的残留可能是分化细胞特有的细胞记忆标记；这一标记在核质重组胚的核重序过程中被去除。

Female gametogenesis in higher plants undergoes various developmental changes, including the de novo formation of germline cells, the differentiation of the megaspore mother cell, meiosis, megaspore selection, and the development of the embryosac.

高等植物雌配子体的形成涉及孢原细胞和大孢子母细胞的确立与分化、大孢子发生、功能大孢子以及胚囊的形成和发育等多种复杂调控过程。随着当代生物技术及功能基因组学的发展，近年对雌配子体发育的研究已从细胞学描述逐渐过渡到对基因和发育调控分子机理的探索。

BMSCs have a high proliferative potential in culture, also they are capable of differentiating to a wide variety of cell types, and when autologous transplanted, there exist no immunorejection. So BMSCs can be used to treat hepar dieases.

骨髓基质干细胞具有容易获得，可以自我复制，高度增殖，在特定的条件下可向各胚层来源的细胞分化的特点，因而将BMSCs细胞移植应用于肝病治疗有非常重要的临床价值。

GFP expression started during gastrulation in the axial hypoblast layer. During segmentation, GFP was detected in the notochord but not in the foor plate.

GFP在原肠作用期就开始表达，主要发生在中轴下胚层中；在体节形成期，GFP在脊索细胞中表达，但未发现在神经底板细胞中表达。

A certain spot in the gastrula begins to act on surrounding cells, thus inducing fast cell division, local expansion, folding, invagination, tubular structures, inclusions, etc.

在原肠胚里某一斑点开始在周围的细胞行动，因此导致快速的细胞分裂、地方扩展、可摺叠、反折处、管状结构、胞吞等。

At the reproductive stage, RA68 was expressed in the inflorescence meristem, the tip of rachis branch, spikelet primordia, macrospore sac and pollen grains.

原位杂交分析结果表明：在幼苗期RA68主要在幼芽胚芽鞘的内外层细胞和幼叶原基的表层细胞中表达；转入生殖生长期后，在花序分生组织、枝梗原基顶端、花器官原基、大孢子囊和花粉粒中表达。

In seed plants also produce spores, and spores are profiled in the ovule Pearl hearts a megaspore mother cell produces large spores by meiosis in the anthers of the microspore mother cells produced by meiosis of microspore.

在种子植物中也产生孢子，且均为孢子异型，在胚珠的珠心中的1个大孢子母细胞经减数分裂产生大孢子，在花药中的小孢子母细胞经减数分裂产生小孢子。

In bud stage, Dlx1 and Dlx2 were expressed in the dental mesenchyme, and in dental epithelium.

蕾状期：Dlx1和Dlx2在成釉器中央细胞及周围外胚间充质细胞为阳性表达。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
