查询词典 postembryonic

Defined as a spectacular postembryonic larva-to-adult transition, it shows a wide morphological diversity between the different chordate lineages, suggesting that it might have appeared several times independently.

在脊索动物的胚胎后发育过程中，不同的谱系中从幼体到成体存在广泛的变态发育，这种现象提示我们，这种形态学上的多样性有可能是通过独立发生的过程而产生的。

Totipotent cells have the capacity to specialize into extraembryonic membra nes and tissues, the embryo, and all postembryonic tissues and organs.

全能细胞具有分化为特定的胚胎外膜和组织、胚胎以及所有胚胎后组织和器官的能力。

The variation to vitellin polypeptide was studied by SDS-PAGE during embryogenic and postembryonic development to Chrysopa septempunctata. The results indicated that vitellin was degradated constantly during embryonic development, and the bands of vitellin couldn't be detected in the 4th day of ovum development.

用SDS-PAGE研究了大草蛉胚胎发育和胚后发育过程中卵黄蛋白多肽的变化动态，结果表明，卵黄蛋白在胚胎发育过程中被不断降解，在卵发育的第4天已经基本上看不到卵黄蛋白的条带。

Nes and tissues, the embryo, and all postembryonic tissues and organs.

全能细胞具有分化为特定的胚胎外膜和组织、胚胎以及所有胚胎

The purpose of the first part of this paper is to investigate whether there are postembryonic pluripotent stem cells in diverse fetal tissues and organs as well as in bone marrow .

本研究的第一部分旨在研究胎儿体内多种组织中是否与骨髓一样，存在有胚胎后亚全能干细胞。

Ten members of the Pax gene family, which perform crucial regulatory functions during embryonic and postembryonic development, have been identified in Drosophila.

果蝇中已发现10个Pax基因家族成员，它们对果蝇胚胎发育及成虫组织器官的分化有非常重要的调控作用。

We propose that ethylene is part of a signaling pathway that modulates cell diision in the quiescent center in the stem cell niche during the postembryonic deelopment of the root system.

我们假设在根系统胚后发育过程中，次乙基调节在干细胞维环境静止中心区域的细胞分裂的一个信号转导通路

To sum up, we first put forward and proved the hypothesis that postembryonic pluripotent stem cells distribute in multiple human tissues, which may help explain the "stem cell plasticity", and that osteoblastic cells were a regulatory component of the hematopoietic stem cell niche by in vitro experiment.

在本论文的第四部分，我们借助体外造血发生模型，首次从另一个角度在体外证明了Scaden及Li等人的实验结果，并证明在造血&龛位&空间组成中，SCF和BMP-4是造血发生的重要调节因子。

So the ability to purify, culture, and manipulate these postembryonic stem cells would provide investigators with an invaluable cell source to study cell and organ development.

因此，对于研究发育生物学而言，能够分离纯化、培养和有效利用胚胎后亚全能干细胞，无疑具有非常重要的意义。

BACKGROUND: At present, studies show that a kind of stem cell community which in many kinds of organizations can differentiate into tissue cells of different embryonic layers; but those are different from embryonic stem cells, embryonic stem cell will lose the part differentiation potential gradually during the development of pregnancy, and will present some special phenotypes or the molecular markers, as CD105 and so on, will call it postembryonic pluripotent stem cells.

背景：目前研究认为在胚胎发育后的多种组织中存在一类干细胞群体，可分化为不同胚层的组织细胞；但又不同于胚胎干细胞，随着妊娠期间胚胎的发育胚胎干细胞会逐渐失去部分分化潜能，会出现一些特殊表型或分子标记，如CD105，称其为胚胎后亚全能干细胞。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
