这会造成两组人群之间的沟通困难，进而影响到公众对重大问题，比如基因技术作物和人类胚胎的利用问题的支持。

The rate of c-kit+ cells in the heart increased gradually from E10 with the highest level of 12.6±3.2% at E11, which was nearly similar to the fetal liver, except for E12 when the c-kit+ cells was 3.4±1.2% in the heart compared to the fetal liver with 11.6±4.1% c-kit+ cells. The rate of c-kit cells in the suspension cells from the heart at E11 maintained stable after 24h culture based in the stromal cells of the heart and AGM region with the same conceptus age, but the rate of c-kit cells obviously decreased in the condition of the stromal cells from the fetal liver. The c-kit cells of the three conditions were all at low level at 48h without significant difference.

通过流式检测c-kit+细胞我们发现，胚胎期心脏和胎肝c-kit+细胞比率几乎一致，E11时c-kit+细胞明显增多，分别高达(12.6±3.2)%和(9.6±2.8)%，但E12时心脏中c-kit+细胞明显减少，仅为(3.4±1.2)%，此时胎肝中c-kit+细胞为(11.6±4.1)%。E11的悬浮细胞与心脏内皮细胞和AGM区基质共培养24h时，c-kit+细胞数量保持稳定，但在胎肝基质细胞中c-kit+细胞数量明显减少，在共培养48h，三组中的c-kit+细胞均呈较低水平，组间没有显著性差异。

Embryonic germ cell lines were isolated and cloned from gonad,gonadal ridge,analogue or the surrounding tissues of 9.5～13.5 days postcoitum mouse fetuses.Primordial germ cells were co-cultured with mouse embryonic fibroblasts obtained from the same conceptus.

自交配后9.5～13.5 d小鼠胎儿生殖嵴/腺或其类似物及周围组织，采用与其同源胎儿成纤维细胞共培养的方式分离克隆到具小鼠ES细胞诸多特征的胚胎生殖细胞系。

These new findings are important for improving induction and conversion frequencies in conifer somatic embryogenesis.

因此，这些新的研究成果对于改善松柏类植物体细胞胚胎发生中的胚的诱导率和转换率低的现象具有重要的意义。

The first part discusses the classifications of human stem cells based on their functional capacities, cellular origins and social contentiousness.

第一部分从干细胞的功能、来源与社会争议性3种角度划分了人类干细胞的种类，并讨论与人类干细胞研究及临床应用相关的9条伦理原则，特别强调了西方国家对胚胎捐赠在知情同意方面的伦理耍求。

The corn snake embryos develop inside the protective, leathery shell.

粟米蛇的胚胎在坚韧的保护壳里发育。

OBJECTIVE: To investigate the effect of Sertoli cells on mouse embryonic cerebral cortical cells in vitro.

目的：探讨睾丸支持细胞对体外培养鼠胚胎大脑皮质细胞的影响。

Of or relating to seed germination in which the cotyledon s remain below the surface of the ground.

地下生的，地下产生子叶的种子萌芽的，或与之有关的，在这种萌芽里胚胎保留在地表面以下

Cotyledon the first leaf of the embryo of seed plants, which is usually simpler in structure than later-formed leaves.

子叶：种子植物胚胎的第一片叶，在结构上通常比后来形成的叶简单。

If human embryo is person, why we never count these into infant mortality rate?

如果人胚胎是人，为什么我们从不将它们计算在婴儿死亡率内？

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。
