查询词典 germ

The morphological transition of the epithelial-mesenchymal compartment by serial transverse sections of the apical end toward the incisal direction is likely to reflect the development of the tooth germ in the prenatal stage.

此上皮突的根冠向连续横断面组织切片显示为上皮—间充质之间形态的转变，就如同胚胎时期牙胚的发育过程。

S inger argues to prenatal geneti c screening and gene selection to presume germ-line cell gene therapy.

基因治的种类及消极、积极基因治疗的界线问题，基因增强、优生学也是我们的重点。

After 6 to 7 days of culture, Eleven ES cell lines were selected and explanted. At last we obtained 4,3,4 and 3 ES cell lines separately. One of the B6C3F_1×B6D2F_1 ES cell lines was selected to future study its competent for germline transmission.We founded the ES cell line has normal karyotype on the chromosome analyse.In teratoma experiment by injected ESCs into C57 mices inguen, we gained teratoma contained cells come from all three embryonic germ layers.

选择一株具有高度杂合背景的B6C3F_1×B6D2F_1 ES细胞系进行核型分析、畸胎瘤实验后与ICR品系2n胚胎构建嵌合体并得到具有生殖系传递能力的嵌合体小鼠，证明此细胞系具有生殖系嵌合能力。

Super results are as follows: the uterus increased visibility one intrauterine gestational sac 10 * 6mm echo, echo germ intracapsular not yet see.

超结果如下：子宫增大，宫腔内可见一10*6mm妊娠囊回声，囊内尚未见胚芽回声。

Eight weeks latter, the left testes were harvested for detection of Johsen's score, ultrastructure of seminiferous tubules, intratesticular testosterone concentration and germ cell apoptotic index.

于VT8周后摘取各组大鼠左侧睾丸，检测其Johnsen's评分、生精小管的超微结构、睾丸组织的睾酮浓度和生精细胞的凋亡指数。

The cases were submitted with diagnoses that included intratubular seminoma, intratubular germ cell neoplasia, unspecified, Sertoli cell hyperplasia, myeloid sarcoma, and lymphoma.

这10例原单位的诊断包括管内精原细胞瘤、管内生殖细胞肿瘤、支持细胞增生、髓细胞肉瘤和淋巴瘤。

There is a significantly difference between the tubular widthes of obstructive and non-obstructive azoospermic patients. The large number of intratubular germ cells within those tubules with active spermatogenesis cause those tubules to be larger than tubules without sperm production.

而藉由测量细精小管，我们得知造精功能受损患者的细精小管管径明显地较具正常造精功能的细精小管细，原因为造精作用活跃的细精小管内生殖细胞较多，因而造成有精子生成的细精小管管径明显的较没有精子生成的细精小管粗。

Here we performed an immunohistochemical study of a novel stem cell marker SALL4 in a large series of 110 primary testicular GCTs (65 pure and 45 mixed) containing the following types of tumors and/or tumor components: 50 intratubular germ cell neoplasias, 62 classic seminomas, 2 spermatocytic seminomas, 39 embryonal carcinomas, 5 pediatric and 26 postpubertal yolk sac tumors, 7 pediatric and 25 postpubertal teratomas, and 5 choriocarcinomas.

在此，我们给110例睾丸原发性GCTs（65例单纯性、45例混合性）做了SALL4免疫染色，研究了这个新标记的诊断效用。

The chair is electrophoresis chart of result that introductor CffA1/Cffa2 expand 22 testing germ.

图为：引物CffA1/引物CffA2对22个供试菌的扩增结果电泳图。

Objective: Identify the human embryonic germ cells by observing the expression of its specific surface markers SSEA-1、SSEA-3. Methods: Human embryonic genital ridges, dorsal mesenteries(5-9 weeks post-fertilization) were cultured without any cytokines, while the fibroblasts derived from the isogenous embryo were used as the feeder layer.

目的：组织块培养法培养人胚胎生殖干细胞，通过检测细胞所表达的阶段特异性胚胎抗原1 和3(stage-specific embryonic antigen-1、3 ，SSEA-1、SSEA-3)，对未分化的人EG 细胞进行特异性的生物学鉴定。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
