2. The tail emerged in the following stage in spermatid phase.

初级精母细胞略小，染色质开始凝集，次级精母细胞开始出现尾部。

3. round spermatid

圆形精子

4. 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。

5. At the latestage of the antheridial development, as the cell wall began to degrade, all of the spermatid cells within anantheridium seem connected with each other by the expanded cytoplasmic bridges.

在精子器发生的后期,当精子细胞壁开始降解时,同一个精子器中所有的精子细胞似乎都由扩大的胞质桥相互连接。

6. progestogen distributed in the cytoplasm of spermatogonia (SPG) and spermatocyte (SPC) dispersedly, after that it existed in the nuclear of spermatid (SPD).

孕激素分布在精原细胞及精母细胞的胞质中，随后在精子细胞的核质中有表达。

7. Comparative Study on the Methods of Early Spermatid Micronucleus Test

小鼠早期精细胞微核试验方法比较研究

8. At the present time, the whole meiotic pr ocess from leptotene spermatocyte to round spermatid of mammal can indeed occur in vitro .

建立生精细胞体外培养模型有助于研究精子发生的调控机制,可用于辅助生育技术,治疗精子发生阻滞的患者；

9. As spermatid nucleus elongates, the chromatin fibers are unwound and join together to form ribbon structure.

当精细胞核向长形转变时,染色质纤维解旋并结合在一起形成缎带结构。

10. An early spermatid had a round nucleus with reticulate chromatins and there were many mitochondria and Golgi vacuoles in the cytoplasm.

早期精子细胞核圆，染色质呈网状分布，胞质中有许多线粒体和高尔基液泡。

11. early spermatid

早精细胞

12. Keywords chronobiology;circadian rhythm gene;Clock gene;round spermatid;acrosome;sperm fertility;

时间生物学;近日节律基因;钟基因;圆形精子;顶体;受精能力;

13. A single centriole appears at the late stage of spermatid.

晚期精细胞中出现单个中心粒，但在成熟精子中消失。

14. undifferentiated spermatid

未分化精子细胞

15. Chromatin hetropycnote partly in spermatogonium, then become highly coacervate to form chromosome at the stage of spermatid and at last decondense at the stage of spermatozoon.

染色质在精原细胞中为部分异固缩，在精母细胞中高度凝聚为染色体，在精细胞及精子中为均匀非致密态。

16. The spermatid began to differentiate, and changed into longer elliptical shape, nuclear-plasm redistributed and moved towards two ends of the cell.

核也为圆形，较小。

17. Keywords Male infertility;Spermatid DNA;Chromatin condensation;Flow cytometry;

18. Keywords Spermatogonia;Spermatid;Haploid;Flagella;

19. The testis at spermatid phase develops continually, and is deep in color, and the spermatogenetic cells in seminiferous tubule are primarily composed of spermatids.

精细胞期，精巢体积继续增大，颜色加深，生精小管内的生殖细胞以精细胞为主；

20. spermatid nucleus

精细胞核

21. Results 70 cases of azoospermia were discovered in 697 cases infertility(10.04%) ， having spermatogenic cell is 42 cases(60%) ， 95.2%has spermatocyte and spermatid ；

结果697例不育者中发现70例无精子，检出率为10.04%，有生精细胞者42例（60%），95.2%有精母细胞和精子细胞；

22. The early spermatid is small with an oval shaped nucleus.

结果显示：早期精细胞圆形，胞质丰富，内含大量内质网小泡及线粒体。

23. The results showed that testosterone was presented in the cytoplasm of spermatogonia (SPG), then it translocated in the nuclear of spermatocyte (SPC) and spermatid (SPD);

结果表明雄激素分布在精原细胞的胞质中，尔后转移到精母细胞及精子细胞的核中；

24. The results indicates that the spermatogenic process was like other teleosts, both included following stages spermatogonium, primary spermatocyte, secondary spermatocyte, spermatid and spermatozoon.

结果表明：黄颡鱼精子发生的过程与其他硬骨鱼类相似，均经历精原细胞、初级精母细胞、次级精母细胞、精子细胞和成熟精子几个时期。

25. We hypothesize that ZNF474 functions as a germ cell-specific transcription factor that plays important roles in spermatid differentiation and oocyte development.
