不分化的

In our research, the genetic identity of 7 populations of 2 species Ambrosia calculated by the Nei method showed that were very similar and above 0.909 in every population.

各种群的遗传一致度较高，均在0.909以上，说明种群之间的差异和分化较小，2种豚草的遗传距离与地理分布不呈正相关。

How mitochondrial biogenesis is integrated with osteoclast differentiation is unknown.

但线粒体的生物发生是怎样和破骨细胞的分化整合到一起的还不清楚。

Microbiopsy of pre-embryos with 4 or 8-cells did not alter their viability and further development. The technique of nested PCR on a single blastomere for the detection of cystic fibrosis ΔF508 mutation is reliable.

在小鼠胚胎4 细胞或8细胞阶段实施单个卵裂球显微活检，不影响胚胎的进一步分化以及小鼠出生后正常生长发育；利用显微活检得到的单个卵裂球进行突变基因诊断是可行的。

The legitimacy of national restriction on the use of embryonic stem cells and Therapeutic Cloning becomes considerably inconvincible.

依「生命历程相对论」的观点，受精十四天内的前胚胎尚未朝各种组织器官分化，应该还不是全然的生命，利用其发展医疗性复制应无道德风险才是。

Because 3 months less than has breed,this is fetal the capacity that still does not have synthetic interferon, boycott the infection of nettle rash virus hard, virus of measles of as a result breeds in great quantities, block sluggish segmentation, the become divided of cloggy organization, form deformation thereby, if harelipped, palate is raided, small head, cataract, congenital obstacle of growth of deaf-mute, bone.

这是因为孕育3个月以内有胎儿尚不具备合成干扰素的能力，难以抵制风疹病毒的感染，以致风疹病毒大量繁殖，阻滞细胞分裂，妨碍组织的分化，从而形成畸形，如兔唇、腭袭、小头、白内障、先天性聋哑、骨发育障碍等。

This type of resolution may be decided at the point of cell division, when asymmetric distribution of regulatory proteins in daughter cells can lead to differential gene expression patterns .

这种分解的类型在细胞分化时就已经决定了。姐妹细胞中的调节蛋白不对称分配时，会导致不同的基因表达方式。

Some inductors are poisonous and cannot be used in human.

背景：体外培养扩增的骨髓间充质干细胞可诱导分化为神经细胞，但是有些诱导剂有一定的毒性，不能应用于人体内。

Under four kinds of different temperature of 20 21,23 25,pollen fertility and rate of selfed seed setting of Dl 8 and D23 are increased a little,their fertility altered.

3水稻光温敏核不育系D18和D23经过幼穗分化不同时期的低温处理，花粉育性和自交结实率有一定的提高，育性得到了转换。

The value for the heat of formation of dibenzofuran and the associated standard entropy are derived from a recent evaluation by Chirico et al.

在这工作。推测必需获得热力学数据为种类benzonaphtho-[1，2-d ]， [ 21， d ] 并且[ 2，3-d ] 噻吩是这样，意味深长的分化在这些异构体之间不是可能的。

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。
