RESULTS:N CAM at muscle canal surface and neuromuscular junction were dyed i...

结果：大鼠胚胎期，肌管的表面和神经肌肉接头部N-CAM呈强烈着染，在发育过程中其浓度逐渐减退，至成年肌肉时几乎消失。

The results showed that there was no significant difference in three structure approach of liquid layers among which B was relatively higher;and it was considered that one-step dilution was an effective preservation method in that survival capacity with frozen and melted embryos freshly split,and survival capacity of frozen and melted IVF embryos split by one-step dilution by application minimum capacity refrigerant method with specific canaliculus were obviously higher than B.

结果，3种不同液体层构成间胚胎的存活能力无显著差异，B法较高；应用特定细管最小容量冷却法在冷冻溶解的新鲜分割胚、体外受精分割胚及冷冻溶解的体外受精分割胚一步法稀释后的存活能力均显著高于B法。结果表明，特定细管最小容量冷却法是更有效的保存方法。

Opponents say that because these embryos are destroyed in the process, this is tantamount to cannibalism.

反对者称因为在这个过程中胚胎被毁掉了，这与破坏的性质一样。

In order to test this hypothesis, we isolated and developed stable self-renewable cell lines of mesenchymal stem cells from human fetal articular cartilage and identified the cell phenotype by FACS and we found that their phenotypic markers were identical to those of mesenchymal stem cells from bone marrow.

我们从胚胎的关节软骨中获得成纤维样细胞，在体外进行培养和扩增，并用流式分析的方法对其表面标志进行鉴定，发现其表面标志与文献报道的骨髓来源的间充质干细胞的表面标志相同。

Motility analysed by CASA is 93. 75%, half of them are move towards ra pidly.

在大黄鱼胚胎超低温保存实验中，逐个筛选了方案中各个因素的最佳水平。

The term caudal means nearer to the tail and is used in description of embryos.

尾侧意指靠近尾部，常用在胚胎的描述中。

The cephalochordate amphioxus has been widely regarded as an important model organism which is the clostest living invertebrate relative to the vertebrates.

文昌鱼是现存的与脊椎动物最接近的非脊椎动物，长期以来文昌鱼一直作为研究动物进化和胚胎发育的模式生物，被称为"活化石"。

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。
