精原细胞

The spermatogonium puirity by centrifugal elutriation were only 60%, but whit higher c-kit cells.

而差速贴壁法回收的精原细胞纯度可达60%左右，但其中c-kit阳性细胞所占比例较大。

On the 10th day, took out testis, fixed in the Boom fixtion solution, conventionally produced and section and stain. Finally observed under the optical microscope. Results The cytoplasm of mesenchymal cell and spermatogonium in test group showed hydropic degeneration.

结果 实验组小鼠睾丸组织中间质细胞和精原细胞胞质呈水样变性，出现红染细小的颗粒状物质，颗粒周围有大小不等的淡染区。

I think there are two important differential diagnoses for this case - seminoma and high grade diffuse large B cell lymphoma.

译：我认为本例有两个重要的鉴别诊断：单纯的精原细胞瘤和高度恶性的弥漫的大B细胞淋巴瘤。

Tumor types include Sertoli cell tumor, seminoma, and interstitial cell tumor.

种类类型包括：支持细胞瘤，精原细胞瘤和间质细胞肿瘤。

Normal testis appears to the left of the mass, and the spermatic cord extends to the left of that.

更大的精原细胞瘤，正常睾丸在肿块左侧，并且精索延伸到那里。

The spermatogonium colonies in the SCs-SSCs co-culture system were at uneven distribution. The brid nest shaped colonies were abundant in perimeter of culture plat.

原代SC-SSC共培养体系精原细胞克隆分布不均匀，在培养得7～10d，培养皿周边长出许多鸟巢状集落。

These data suggested that the centrin isoforms played different roles in different stages of spermatogenesis. The centrin-1 gene was revealed to be relevant to the centriolar translocation to the posterior pole of cell and the elaboration of flagellum during spermiogenesis, while the centrin-2 and centrin-3 might play roles in spermatogonial mitosis but were not involved in the spermatid differentiation process.

这些结果提示，Centrin同源基因在精子发生的不同阶段发挥不同功能，其中Centrin-1与精子细胞分化期的中心体后移、鞭毛的生成及精子中轴形成可能密切相关，Centrin-2和-3则可能在精原细胞有丝分裂中起作用，而与精子细胞变态分化无关。

Except for hemopoietic progenitor cells, spermatogenous cells and oocyts, there was no expression of hTERT in other somatic cells.

除造血祖细胞、精原细胞和卵母细胞表达外，其他正常体细胞中均不表达hTERT。

On the basis, silkworm vasa gene has been studied by in situ hybridization on gonads.

结果表明，家蚕vasa基因在幼虫期只在生殖系相关的细胞和组织中表达(如精原细胞，精囊，卵巢管等)，而在其它组织细胞中不表达。

Epithelial cells of hepatopancreas and midgut, and male and female reproductive system were not sensitive to the WSSB...

WSSBV对中肠和中肠育囊上皮细胞，肝胰腺上皮细胞，雄性生殖系统精原细胞，输精管上皮细胞等不敏感。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
