For these years, residua of metanephric blastema and delay of differentiation in the development of kidney have been considered the cause of nephroblastoma.

近年来的研究发现，肾发育过程中的胚基残留，分化障碍可能是肾母细胞瘤发病的原因之一。

Wilms" tumor is one of the most common solid tumors in children, and the genesis of Wilms" tumor is believed to be associated with delayed differentiation of metanephric blastema in fetus and retaining proliferation in postnatal period.

肾母细胞瘤（Wilms tumor， WT）是儿童最常见的实体瘤之一，其发病与后肾胚基细胞分化受阻并在出生后继续增殖有关。

If viable nervous tissue is not present from the start of the amputation but brought into the so-called blastema shortly afterward, regeneration takes place but the regenerate limb is poorly developed.

如果，神经细胞不是在开始截肢的时候就找到，是被带到之后所谓的胚芽，「再生」就会开始。

The nerve need not be present throughout the entire period of regeneration; once the limb has begun to grow and tissues are sufficiently differentiated, the nerve may be removed without impariment of the morphegenetic potency acquired by these tissues during their earliest stage of formation. Singer (1974) has shown that it does not matter for regeneration what type of nerve, whether motor, sensory, or autonomic, is present in the blastema.

但是再生的肋骨市是「不完全发育」，神经不会在整个再生过程中呈现出来；一旦，肋骨开始生长，而且组织得到足够的养分，神经就可以从器官器官再生的部位移除，力量，是细胞在早期形成的时间得到的Singer，则证明了：任何细胞组织，对再生来说，是不相关的，不管是运动、感觉、自动的，都在胚芽中呈现。

The epithelial elements surround nodules of blastema and are attempting for form rosettes.

镜下常见有三种成分：后肾胚芽组织、上皮组织及间叶组织不等量混合存在。

Blastema in WT consists of sheets of densely packed small blue cells with hyperchromatic nuclei, little cytoplasm and conspicuous mitotic actiity.

缩略图，点击图片链接看原图）后肾胚芽由密集排列的片状小蓝色的细胞构成，核染色质粗糙，胞浆稀少，有丝分裂像明显。

By this time, it has developed into a hollow ball of cells called blastocyst .

到这个时候，它已经发育成一个叫囊胚的中空细胞球了。

There is a good deal of variation in blastocyst size before implantation but it is not known whether this is related to survival rate.

囊胚的大小在定植前有很大的差异，但是目前还不知道这会不会影响到胚胎的存活率。

These data suggest that an active blastocyst is required for STAT3 activation which may be important for embryo implantation.

这些结果表明STAT3的激活需要活性胚泡的存在，可能在胚胎着床过程中起重要作用。

IT IS hard for some people to see the small cluster of cells known as a blastocyst as a human being.

人们很难将一小串胚泡细胞看作是一个人。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
