Research in the relation between telomerase reverse transcriptase expression in spermatogenic cells and serun levels of estradiol of fluorotic rats 染氟大鼠血清雌二醇水平与生精细胞端粒酶逆转录酶表达关系的研究
While in the 30 % fraction , immature spermatogenic cells were present , and more than 92 % of the cells remained their viability 5以上细胞存活； 630opercoll组分中细胞密度最高po0 05 ） ，含有各级来成熟生精细胞，存活细胞超过92 。
1 . spermatogenesis spermatogenesis can be devided into five stagesrspermatogonium , primary spermatocyte , secondary spermatocyte , spermatozon and sperm 精子发生精子发生可分为精原细胞、初级精母细胞、次级精母细胞、精细胞、精子五个阶段。
The results showed that distribution of 37 and 39kd peptides on the plasma membrane surface of sperm cells of maize with visible immunogold particles to be localized 免疫定位表明， 37kd , 39kd多肽是玉米精细胞质膜所特异的。有关此多肽的功能有待进一步研究。
The results reveal that there are two types of spermatogonium , primary spermatogonia ( sg1 ) and secondary spermatogonia ( sg2 ) , in the early developmental stage of testes 生精细胞之间存在着间桥连接。大眼鳜具有初级精原细胞、次级精原细胞两种类型精原细胞。
Spermatogenesis macrobrachium rosenbergii during spermatogenesis , chromatins keep on condensing until mid - spermatid stage . the nucleus changes into two forms : fibrous and homogeneous forms 精子发生罗氏沼虾精子发生过程中染色质凝集程度逐渐增大，至精细胞中期凝集程度达到最大。
