| 7. | A variety of biology events occur during spermatogenesis , such as self - renewal of spermatogonia , meiotic division of spermatocyte and the spermiogenesis of spermatid
生精过程中发生了许多生物学的变化，如精原细胞的自我更新，精母细胞的减数分裂和精子细胞的变形。 |
| 8. | P and pr have relationships with spermatogensis and sperm maturation . 6 . the product of c - fos translocates from the cytoplasm of spermatogonia to nuclei of spermatogonia , then it induces the transcription of dna and regulate spermatogonial proliferation and spermatogenesis
C fos产物从精原细胞胞质中转移到胞核中后通过启动dna的转录而调控精原细胞的增殖，从而促进精子发生的进程。 |
| 9. | According to the changes of the structure of chromatin and the morphology of cell , the process of the typical spermatogenesis of cipangopaludina chinensis can be divided into five stages : spermatogonium , primary spermatocyte , secondary spermatocyte , spermatid and mature sperm
