During male gametogenesis , the spermatogonia became primary spermatozoa through mitosis , and then became fourth equivalent cytoplasm , round sperm through meiosis . after maturation , they participated in embryo development with the mature oocyte through fertilization . but in female gametogenesis , the primary oocyte formed a matured egg and 1 ~ 3 polar bodies ( pb ) 雄性動物精子發生過程中精原細胞最后一次有絲分裂形成二倍體精母細胞后，經過兩次減數分裂形成了四個含等量細胞質、圓形的精子細胞，最終發育成四個具有正常生理功能的精子，與成熟卵母細胞受精后參與胚胎發育。 |

Glial cell line - derived neurotrophic factor ( gdnf ) was originally isolated based on its potent and specific ability to promote the survival and morphological differentiation of dopaminergic neurons and motoneurons in embryonic midbrain cultures . in addition , gdnf also support the survival and regulate the differentiation of many peripheral neurons , including sympathetic , parasympathetic , sensory and enteric neurons . gdnf also plays a crucial role outside the nervous system , as a morphogenetic factor in kidney development and as a regulator of spermatogonia differentiation Gfr 1與gdnf結合位點的研究膠質細胞源性神經營養因子( gdnf )對多巴胺能神經元、運動神經元、感覺神經元、腸道神經元等多種神經元具有促進存活及保護作用，它還能促進腎臟的發育和精原細胞的成熟，因此，極有希望用于治療神經損傷和神經系統退行性病變。 |

The males incubation at 26 , cortices of their testes degenerate into a thin albuginea . medulla are formed by testicular cords in which scatter spermatogonium 26下孵化的小龜精巢皮質退化成為一層薄的白膜，髓質有許多睪丸管構成，管腔內有散落排列的精原細胞。 |

The results reveal that there are two types of spermatogonium , primary spermatogonia ( sg1 ) and secondary spermatogonia ( sg2 ) , in the early developmental stage of testes 生精細胞之間存在著間橋連接。大眼鱖具有初級精原細胞、次級精原細胞兩種類型精原細胞。 |

During the stages of primary and secondary spermatogonium , components of the nucleolus , called chromatoid bodies ( cb ) , are excluded from the nucleus 精原細胞階段，部分核仁物質外排，成為擬染色質小體，其上聚集一群線粒體，構成“線粒體區” 。 |

1 . with testicular development , the products of c - myc translocate from the cytoplasm of spermatogonia to nuclei of spermatogonia 隨著精子發育時期的不同， cngc產物在山溪蛻精巢中有從生殖細胞的胞質向胞核中轉移的趨勢。 |
