胚胎发育

Yet, all being well, it will become one—for a blastocyst is an early stage in embryonic development.

然而，如果这些胚泡细胞发育得当，它们的确可以生长成一个人，因为胚泡是胚胎发育的早期阶段。

Subsequently , people found that noggin plays an important role in normal development, especially of inducing dorsal development.

此后发现该基因在胚胎发育中有重要神经诱导作用，尤其是诱导外胚层的背侧发育。

This system is simple and stable, and therefore can be a useful tool for the study of embryogenesis mechanism.

此体系操作简单，稳定性好，且关键发育事件的时空调控与自然胚胎发育进程相吻合。

Embryoid bodies provide an unprecedented opportunity to study the events regulating lineage commitment, and tissue growth and maturation during embryonic development.

胚体提供了一个前所未有的机会来研究活动调节系承诺，并组织发育和成熟的胚胎发育过程中。

Pachygyria is a neuronal migration disorder that develops during the 12th to 24th week of embryologic development, and results in various degrees of muscle spasm, hyperreflexia, seizures, developmental delay, and mental retardation.

巨脑回是一种神经移行障碍，发生于胚胎发育的12-24周，其导致不同程度的肌痉挛、反射亢进、癫痫发作、发育延迟和智力低下

These genes play a central role in the developmental processes of the anterior-posterior axis of vertebrates by regulating the fetation,and define body pattern in the vertebrates.

这些基因调节胚胎发育，尤其在脊椎动物前-后轴(antero-posterior axis)的发育过程中起着重要作用，并指导脊椎动物的体型形成。

Because the vertebrates express anatomical characteristics consistently during the process of fetation, many researchers conjectured ancient vertebrates by the characteristics of the animals living nowadays and speculate the origin and the process of evolution.

由於所有的脊椎动物在其胚胎发育中都呈现连续的解剖学特徵，因此过去很多学者都根据现存脊椎动物的形态特徵和在其发育过程中的解剖学特徵假想原始脊椎动物，并推导其进化过程和起源。

The expression pattern of gibel carp pou2 suggests that this gene should play an important role during early stages of embryogenesis. It might regulate the formation of neural plate and the fate of midbrain and hindbrain cells during early embryogenesis.

银鲫pou2基因的表达图式提示该基因在胚胎发育的早期具有重要作用，它可能参与调控神经板的形成和中后脑细胞的发育命运。

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。
