The GFRαl mRNA was expressed by undifferential spermatogonial cells.

GFRα1 mRNA主要由未分化精原细胞表达。

It is practical that using the spermatogonial cells as the vector to produce the transgenic mice of HBx and ras gene, and could play a role in establishing transgenic animal model of tree shrews.

以精原细胞作为载体，建立带HBx及ras基因的小鼠模型是可行的，为建立树的转基因动物模型的研究打下基础。

This high level expansion of cell cultures uses the stimulatory effect of acidic fibroblast growth factor and heparin.

房间文化的这高级的膨胀使用酸性的纤维原细胞生长因素的stimulatory作用并且肝磷脂。

Male conceptacles contain branched paraphyses that bear the antheridia.

In primary spermatogonia, mitochondria were larger and spherical, and contained few cristae.

在初级精原细胞阶段，线粒体较大，多为球形，嵴少，基质电子密度低。

There was no typical Golgi complex in oogonia, but there were some Golgi vesicles. At the early stage of vitellogenesis, Golgi complex was abundant whose saccules increased to more than ten layers. At the middle stage of vitellogenesis, Golgi complex grew more in numbers and got together, so its secreting quickened. Moreover, it formed a number of Golgi vesicles, which were filled with granule substances that changed into yolk granule finally.

卵原细胞内无典型的高尔基复合体，但具高尔基囊泡；卵黄发生早期，高尔基复合体发达，膜囊数达10多层；卵黄发生中期，高尔基复合体分泌活动加快，产生大量的大小囊泡，囊泡内充满颗粒状物质，最后演变成卵黄颗粒。

Increased accumulation of acidic fibroblast growth factor in left ventricular myocytes of patients with idiopathic cardiomyopathy.

在病人的左方的心室的myocytes与先天的心肌症增加了酸性的纤维原细胞生长因素的累积。

Next, Dr LaVan and his colleagues installed a protein called alpha-hemolysin into the protocell membrane. This functioned as a selective bridge, permitting the passage of positively charged sodium ions, but not negatively charged chloride ions.

接下来，拉文和他的同事们在原细胞的细胞膜中加入了一种叫阿尔法溶血素的蛋白质，这样就建立了一个选择性的通道——允许正极的钠离子通过，却阻止负极的氯离子。
