查询词典 fertilization

In the experiment besides entire spermatophore transplantation and spermaduct transplantation, partial spermatophore transplantation and semen transplantation were firstly used in artificial insemination of Fenneropenaeus chinensis. Artificial insemination rate, fertilization rate and hatching rate were compared among the four methods. The results indicated that artificial insemination rate of four methods was high, the highest was 80.8% and the lowest was 53.3%.

在常规的精荚移植和输精管移植两种中国对虾人工授精方法的基础上，首次建立了精荚切块移植和精液移植两种新的人工授精方法，并对比了4种方法的授精成功率、受精率和幼体的孵化率。4种方法都取得了较好的授精成功率，其中完整精荚移植法最高，为80.8%；输精管移植法最低，为53.3%；其他两种方法依次为：精液移植法为73.9%，精荚切块移植法为66%。

Pem gene is expressed in a time and stage specific manner. Pem transcripts are detectable as early as day 6 in mouse embryonic development, and are abundant in day 7 and 8, but decrease precipitously thereafter. Although Pem transcripts are not detectable in most of adult tissues, they are present in reproductive system. Furthermore, Pem has also shown to be specifically expressed in the proximal cauda and distal corpus regions of the epididymis, the regions where spermatozoa gain forward motility and fertilization competence.

Pem基因的表达具有明显的时间和空间特异性：在鼠胚发育的第6天，即可检测到Pem转录本的表达；第7-8天，Pem表达量达到最高，随后迅速减少；Pem基因在成年组织中一般不表达，但可在生殖组织表达；另外，Pem特异地在附睾近侧尾部和远侧的体部中表达，此处是精子获得运动性和受精能力的地方。
