The identification and study of the control factors that regulate gene expression at different stages are of great value to elucidate the mechanism of spermatogenesis and spermiogenesis. Such study can also provide foundation and cues to investigating the mechanism of infertility and immunological contraception.

作为体内高度分化的雄性生殖细胞，精子发生过程中经历了从形态到生化的复杂变化，在这一过程中有一系列的特定基因按严格的时空顺序转录和翻译，因此寻找和研究不同发育阶段的差异表达的基因，将有助于最终阐明精子发生的机理，并为控制生育和不育机理的探索提供新的线索。

A developmental process termed spermiogenesis takes place to generate motile sperm from round spermatids in mammals.

中文摘要哺乳动物中，圆形的精子细胞必须经过一系列形态变化才能发育成为成熟的、能游动的精子。

It is reported that KAP-1 related transcription regulation complexes exert functions essen-tial for spermiogenesis and early embryo development. This regulation is one pattern of epigenetic regulations.

KAP-1参与形成的复合体在精细胞发育、胚胎早期发育等生理过程中发挥重要的调控作用，这种调控属于表观遗传调控范畴。

Spermiogenesis is a crucial process for germ cell formation, which ensures the efficient transmission of the paternal genome by the spermatozoa to the ooctyte at fertilization.

它包括染色质的压缩、顶体和鞭毛的形成以及去除多余的细胞质，是精子发生的一个重要环节，确保了成熟精子具有正确的形态和完整的功能。

Spermatogenesis is a continuum of cellular differentiation in which three principal phases can be discerned: spermatogonia renewal and proliferation, meiosis and spermiogenesis.

睾丸的精子发生是一个独特复杂的细胞分裂分化过程。

The immunostianing of ghrelin was not observed in Leydig cells after the impairment. Conclusion The changes in the expression of ghrelin suggest that ghrelin may play an important role in the function regulation of testis and the process of spermatogenesis and spermiogenesis.

结论Ghrelin在小鼠正常及辐射损伤睾丸中的特异性表达和变化，提示其可能与睾丸精子发生、精子形成及辐射损伤修复有关，具有重要的睾丸生物学调节功能。

Targeted disruption of the Ppp1cc gene, which encodes the PP1 gamma 1 or PP1 gamma 2 isoforms, causes male infertility in mice as a result of impaired spermiogenesis.

编码PP1γ1或PP1γ2的Ppp1cc基因缺失的雄性小鼠由于精子发生的削弱导致雄性不育。

When adult male rabbit were immunized with rSMP-B, their spermatogenesis was blocked at spermatid stage. It suggested that rSMP-B might play an important role in spermatogenesis and spermiogenesis.

斑点杂交法表明该抗体与人及大鼠睾丸细胞质中的一种特异性蛋白发生交叉反应，提示rSMP-B具有种属同源性，其抗体有较强的抗育作用。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
