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。

The results showed:(1) the cellule morphous and the disposition in chick embryo of PGCs were coincident no matter stained by PAS or HE staining, and HE staining could disclose the morphologic characteristics more clearly, exactly and completely;(2) genesis of blood island could be observed at the boundary of light and dark region of the extraembryonic blastoderm at about 26 hours;(3) both the blood vessel endothelium cells and free cells of the blood island were differentiated from PGCs. The generating of genuine yolk sac was at about 44-48 hours.

结果表明：①用经典的识别原生殖细胞的PAS染色方法与HE染色所观察到的PGC在鸡胚的分布及细胞形态基本一致，而HE染色较PAS法能更有助于清晰、完整、准确地识别PGC的细胞内部结构特征；②在孵化26小时的鸡胚胚外胚盘的明暗交界处可见血岛的发生，血岛发生的时间比真正的卵黄囊产生时间（大约44-48小时）要早很多；③血岛周围的血管内皮细胞与管腔中游离细胞都来自PGC。

It is concluded that the initial ancotomic site of blood island genesis may be is mesoblast of extraembryonic blastoderm rather than the yolk sac; the blood vessel endothelium cells and the blood cells are generated parallel; the PGCs are the common ancestry of angioblast and HSC.

血岛最早发生的解剖位置可能不是卵黄囊而是胚外胚盘中胚层，血管内皮细胞与血细胞平行发生，PGC是成血管－造血干细胞的共同祖先。

The tree is still quite small, and the apple is about the size of a golf ball," explained Boyer, who noted that the tree will eventually grow to a height of approximately 10-12 metres."But it's really quite amazing when you think about the genesis of it.

"树还是相当小，苹果约有一个高尔夫球的大小"，博耶解释说，并指出该树最终将发展到高度约10至12米，"这的确是非常令人惊异的事，如果你想想它的起源"。

It shows from the geological and geochemical characteristics of the two gold deposit that they belong to the series of the interstratified glide breccia type gold deposit s with the same genesis and source which a.

金矿地质及地球化学研究表明，蓬家夼金矿和发云夼金矿是属于在相似地质条件下在同一地质作用过程中形成的具有同成因同来源的层间滑动角砾岩型金矿。

Guided by plate tectonic theory and combined with the analysis of the metallogenetic geotectonic setting, geological and geochemistry characteristics, genesis and brecciation mechanism in Shuangwang gold deposit s in China,this paper established location model of ore-fluidic fracture.

以板块理论为指导，论文对双王金矿床产出的构造背景、矿床地质地球化学特征、矿床成因、角砾岩形成机制进行了研究，建立了矿床的矿液致裂构造定位模式，并结合成矿模式及地质、地球物理、地球化学找矿标志对已知矿体的深边部及外围进行了成矿预测研究。

The genesis of the games came in 1948, when German neurologist Ludwig Guttman organized an athletic event in Buckinghamshire -- northwest of central London -- for soldiers wounded in World War II.

残奥会开始于1948年的德国神经学家路德维格Guttman在中央伦敦西北部的Buckinghamshire为二战中受伤的战士组织的一次运动会。

But the genesis of the carbonite reservoir rocks, the differences in lithology, diagenesis, post diagenesis, structural fractures and dissolution have made it difficult for the general concepts and methods of the flow units to be suitably used in fracture-and-cavernous carbonate reservoirs.

主要储集空间以构造变形产生的构造裂缝与岩溶作用形成的孔、洞、缝为主，其中大型洞穴是最主要的储集空间，裂缝既是主要的储集空间，也是主要的连通通道。塔里木盆地塔河碳酸盐岩油田即属于此类油藏。
