An endodermal sinus tumor of the testis is shown composed of primitive germ cells that form glomeruloid or embryonal-like structures.

睾丸的内胚层窦肿瘤由原始生殖细胞构成，这些细胞形成血管球或胚芽样结构。

Our three groups in SCBB will conduct one project in this grant (three projects in this grant total), which is "Screen mutants interfering the development or regeneration of endodermal organs and study their functional mechanisms". In this project, stem cell and zebrafish will be used as models to elucidate the mechanisms of the development of endodermal organs.

我院的三个课题组负责此项目的课题三《正向遗传突变筛选具有内胚层器官发育或再生缺陷的突变体及致变基因的功能机制研究》，将采用干细胞和斑马鱼模型，研究内胚层器官的机制，特别是分子调节网络的整体性和时空性，为防治肝脏和胰腺的重大疾病提供坚实的理论基础。

From the treatment of endometritis after collection embryo to interval time of the finst heat of restoration of reproductive capacity and to interval time of conception ,these aspects were＇ clinically examined.

对采卵的处理情况和后续的子宫卵巢机能恢复后再配种受胎情况，冲胚时间至治疗后第1次发情时间，冲胚时间至受胎时间进行了临床效果观察。

This difference enables seeds to be classified as nonendospermic or endospermic.

可以凭借这种结构上的差别将种子分为有胚乳种子和无胚乳种子两类。

Aim:To explore the feasibility of neural stem cells derived from both fetal rat ependyma and adult rat bone marrow.

目的 ：探寻胚鼠室管膜和成鼠骨髓分离培养神经干细胞的可行性。方法：将分离的胚脑室管膜组织或成年骨髓细胞分别特殊培养。

Embryo with cotyledons much smaller than the hypocotyl; leaves small, often ericoid.

胚具子叶很多小于下胚轴；叶小，通常。 4 Baeckea 岗松属

In exalbuminous seeds, the endosperm is short-lived.

在无胚乳的种子中，胚乳是短命的。

Seeds erect or pendulous, sometimes winged, usually exalbuminous, very rarely with thin endosperm; cotyledons mostly fleshy and convex abaxially, rarely folded or convolute.

种子直立或者倒生，有时具翅，通常无胚乳，极少有薄的胚乳；子叶几乎肉质并且背面凸，很少折叠或旋卷。

Seeds solitary, exalbuminous; testa membranous; cotyledons usually membranous, contortuplicate, rarely fleshy and planoconvex; radicle superior.

种子单生，无胚乳；种皮膜质；子叶通常膜质，卷折，很少肉质和平凸；胚根上位。

Seed horizontal, lenticular; testa leathery, lustrous; embryo annular; perisperm farinaceous.

种子水平，透镜状；种皮似皮革，有光泽；胚环状；外胚乳谷粉制。
