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。

The eccrine sweat unit is composed of three sections that are modified from the tubular structure that formed during embryogenesis as a downgrowth of surface epidermis.

小汗腺单位由三部分组成，它由胚胎形成时自表面表皮向下生长形成的基本管状结构转化而成。

What Homeotic gene is controlling embryonic development and dry cell is newer.

Homeotic基因控制着胚胎发育和干细胞的更新。

This center passes classics rectum seminiferous duct crock abdomen, spermatic gland, prostate massages art extraction essence of life to be able to avoid this kind of injury and anguish very well, and obtain enough spermatozoon to be used at ICSI and IVF-ET, report as follows now.

梗概： 隨着现代辅助生殖技术的发展，体外受精-胚胎移植及其相关技术成为治疗不孕不育症主要方法之一，对于精液中有精子者一般通过患者手淫取精用于体外受精。

In the embryo before, you will always be pain, the pain has been, if you have normal dysmenorrhea, more pain!

在胚胎出来之前，你会一直痛，一直痛，如果你平时有痛经的话，会更痛！

The dorsal system is necessary for the development of ventral structures including the mesoderm and neurogenic ectoderm.

Morphorgenesis and differentiation of these organs involves sequential and complex interaction between ectoderm, mesoderm and endoderm.

这些器官的成型与分化，皆是由胚胎外、中、内三个胚层组织一连串的讯息传递以及彼此之间的交互作用所完成的。

They are also aiming at the areas, including molecular control of neural differentiation from uncommitted ectoderm, molecular basis for diversity of neurons, molecular basis for fine positional information during early embryogenesis and in vitro differentiation of ES cells into neural tissues etc.

他们还致力于未成熟外胚层神经分化的分子控制；神经元多样性的分子基础；早期胚胎发育阶段，细微的位置信息的分子基础；进入神经组织的ES细胞的微分化等领域的研究。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
