  • primary : adj 1 第一的，最初的，初級的；初等的；基本的；基層的。2 主要的，為首的，第一位的。3 原始的，根本...
  • spermatocyte : n. 【生物學】精母細胞 （＝sperm mother cell）。
  1. 1. spermatogenesis spermatogenesis can be devided into five stagesrspermatogonium, primary spermatocyte, secondary spermatocyte, spermatozon and sperm

    精子發生精子發生可分為精原細胞、初級精母細胞、次級精母細胞、精細胞、精子五個階段。
  2. 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

    中國圓田螺典型精子發生時，根據染色質和細胞形態的變化，可將其發生分為以下五個時期：精原細胞、初級精母細胞、次級精母細胞、精細胞和成熟精子。
  3. At the beginning, the cytoplasm is evently distributed, then it is polar - distribution and at last it only remains between the apical cap and the sperm nucleus. during the period of spermatogonium, chromatin in the nucleus is in the shape of conglomeration and the nucleus is big ( i. e. the proportion of the nucleus to cytoplasm is bigger than spermatocyte ). at the stage of primary spermatocyte, chromatin accumulates to sc complexity. the nucleus of the mature sperm takes the shape of a plate and filmentous chromatins exist freely in uncondensed nucleus

    精子發生過程中，細胞器由少到多，到最後解體；細胞質從均勻分佈，到精細胞期極性分佈，最後殘留于成熟精子的頂帽和精核之間；細胞核在精原細胞期，染色質異固縮，胞核大，即核質比大於后續的精母細胞；在初級精母細胞中，染色質凝聚為sc復合體，到成熟精子，精核呈碟狀，染色質呈絲狀游離于非濃縮的核中。
  4. The expression and activity of cdc2 in spermatogenesis cdc2 is emergent in 10 days primary spermatocyte, but the expression is at a low level because the testicles are not right in scrotum, which can lead the germ cells stop to grow, however, the expression of cdc2 begins to increase since 20 days, which can improve the meiosis. the expression is also showed in sperm, which is the end of meiosis. the data showed that the phosphorylation of cdc2 tryl5 in germ cells is increase with

    Cdcz場巧的磷酸化抑制cdcz的活性，它的磷酸化可以導致mpf復合物解離，使其失去生物活性，綜合以上實驗結果可以說明:在雄性小鼠生殖細胞發育過程中， cdcz在精原細胞、初級精母細胞及精子細胞中表達，隨著翠丸組織中生殖細胞的不斷成熟，生殖細胞中cdcz活性逐漸下降; cdcz在精子中同樣存在，但已失去其生物活性。
