The gross and microscopic appearance of an ovarian dysgerminoma is essentially the same as a seminoma of the testis in a male.

从大体及镜下观察卵巢的无性细胞瘤与男性的睾丸精原细胞瘤是一样的。

On the D110, when mean total length reached about 86.5±5.9 mm, ovarian cavity grew bigger, and oocytes were firstly detected. Differentiation of testis was firstly observed in juvenile flounder with mean total length of 63.5±3.4 mm on the D90 when spermatogenous cell proliferated rapidly and spermaduct formed.

在90日龄、平均全长为63.5±3.4 mm的雄性牙鲆中，精原细胞快速增殖，并观察到了输精管结构；进一步的细胞学分化则出现在100日龄、平均全长为76.0±8.6 mm的个体中，此时可以看到精小叶的形成；在平均全长为140.0±15.2 mm时，精巢中出现初级精母细胞，标志着性腺分化的基本完成。

In male, the immunopositive reaction in spermatogonia, spermatocyte and spermatid to testosterone antibodies strengthened gradually during the development and maturation of testis.

在大生长期和成熟期，精原细胞和精母细胞对孕酮抗体发生强的免疫阳性反应。

They were expressed abundantly in the spermatogonia cells but decreased markedly when the cell grew into the meiotic spermatocyte stage.

它们在睾丸精原细胞中有高表达，但到精母细胞进入减数分裂时则mRNA水平迅速降低。

Leb regarding the treatment of osteoporosis with electromagnetic field were built on the clinical studies of Basset, Brighton, Becker, Cruess, Janssen, Lengel, Rubin and Wallach, among which the cell cultivation study made by Rodermann, Bayreuther and Pfederer in 1985,that is the reaction of human skin and pulmonary collagen cells to certain electromagnetic field intensity and alternating density, exerted the biggest influence on Professor W.

Leb教授运用电磁场治疗骨质疏松的治疗计划与规则是建立在Basset，Brighton，Becker， Cruess， Janssen， Lengel， Rubin∫ Wallach 的临床研究基础之上的，其中 Rodemann， Bayreuther和Pfecderer于1985年开展的细胞培养研究，即人类皮肤、肺成胶原细胞对一定电磁场强度和交变密度的反应对W。

Microscopic observation on anther development process of cytoplasmic male sterile line"1815A"showed that its anther development was inhibited at the stage of archesporial cell differentiation.

以1815A不育系对应的保持系1815B作对照，对不育系进行细胞学观察，结果表明：随着花蕾的发育，败育的雄蕊一直处于孢原细胞时期，不能形成花粉囊并产生花粉母细胞，但雌蕊和维管束组织发育正常。

Growth stimulation of rat calvaria osteoblastic cells by acidic fibroblast growth factor.

由酸性的纤维原细胞生长因素的老鼠头顶osteoblastic细胞的生长激励。

Another type of cell called a chondroblast forms new cartilage.

名叫软骨原细胞的另一种细胞会形成新的软骨。

Mononucleated trophoblastic cells were variably positive for SALL4 staining in all 5 choriocarcinomas.

所有ITGCNs、经典型精原细胞瘤和ECs病例90%以上的瘤细胞强烈表达SALL4和OCT4。

Sinensis could be divided into 5 stages, includi ng t he spermospore proliferation stage, the primary spermatocyte stage, the secondar y spermatocyte stage, the spermateliosis stage and the spermiotiliosis stage.

在整个精子发生过程中，N-乙酰半乳糖复合物出现于精原细胞期，并于精母细胞期发生明显的修饰和变化，精子形成期和成熟期没有N-乙酰半乳糖复合物的表达。

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。
