查询词典 embryonic disk

Opportunistically expressed (usually at the basal levels of transcription), but still permit the continued expression of genes that are regulated by strong promoters/enhancers (such as housing-keeping gene), the expresison of these genes might play a key role in the embryonic development; 5 The sum of these two opposing processes-activation and repression-would dictate the final pattern of gene expression that manifests itself as a dramatic reprogramming of gene expression during the maternal-to-zygotic transition and support further embryonic development.

这些基因的表达对于胚胎的后继发育可能是至关重要的；5）通过胚胎基因表达的激活与抑制：这两个作用相反的机制依不同时间顺序协同作用于胚胎基因，从而在指导胚胎发育的控制权由母源性表达产物移交到胚胎特异的基因表达产物的过程中&再程序化&胚胎基因的表达，形成特定的表达模式，以支持胚胎的后继发育。

As soon as embryonic tissues are sufficiently differentiated movement and primitive stages of behavior appear, and these develop pari passu with further embryonic development.

We suppose that there is a presently undefined subfraction of stem cell population that exists in a number of tissues beyond embryonic development. We term them postembryonic pluripotent stem cells. They differ from embryonic stem cells in that they gradually lose some differentiation potentials during development and adopt some special phenotypes once within a certain tissue. They can give rise to different kinds of stem cells; therefore, help to maintain balance during development and metabolism. They provide cells not only for the damaged tissues they reside, but also for damaged tissues different from them by migration triggered by proinflammatory cytokines or growth factors.

我们认为在胚胎发育后的多种组织中都存在一类原始干细胞群体，它们和造血干细胞、神经干细胞等多能干细胞不同，后者只能分化为特定胚层的细胞，而这类原始干细胞可分化为不同胚层的组织细胞；另一方面，它们区别于胚胎干细胞，在妊娠期间会逐渐失去部分分化潜能，并且会出现一些特殊表型或者分子标志，我们称其为胚胎后亚全能干细胞，这类干细胞具有下列特性：可分化为不同胚层的细胞，分布于身体的所有组织和器官，具有相同的表型或标志；他们在胚胎期存在于一些或全部的组织和器官中，可分化为不同类型的多能干细胞并在生长发育和新陈代谢中维持这些多能干细胞保持平衡；可以参与机体自我修复和更新，不仅能分化为所在器官的组织特异性细胞，参与器官重塑，也可以在炎症因子或者生长因子的趋化作用下，远处转移修复受损组织。

The reprogarmming of embryonic genome is likely the molecular foundation of the transition of highly differentiated oocytes into totipotential embryonic blastomeres.

基因表达的&再程序化&可能是高度分化的卵母细胞转变成胚胎中具发育全能性分裂球的分子基础。
