To isolate spermotogonia using two combinatorial enzyme three step wises digest the testicular tissues from 19 d-old-embryo after hatching,the cryopreserve effect of dimethylsulphoxide,glycerol and ethylene glycol cryoprotectants,each at(5%,10%,and 15%) concentration on the 19 d chicken embryonic SSCs was compared with fast freeze method.

采用二酶3步法获取孵化第19 d的鸡胚精原干细胞，比较在快速冷冻条件下3种冷冻保护剂(DMSO、乙二醇、甘油)在3个浓度5%、10%、15%条件下对鸡胚精原干细胞的冷冻保存效果进行研究。

In other words, the embryonic period and the infancy of testicular tubules is solid thin tube, did not occur and mature sperm.

也就是说，胚胎期和婴儿期睾丸内的曲细精管是实心的细管，并没有精子的发生和成熟。

Results: it was efficient to transfect chicken embryonic fibroblast cells by the method of lipofectamine mediation. the expression levels of protein were significantly different.

Methods The guts of embryonic mice removed and dissociated were plated into serum-free DMEM/F12 medium. The mitogen-free DMEM/F12 medium supplementd with 10% fetal bovine serum was used to induce differentiation of GNCSCs. Neurospheres and their derivations were determined with immunocytochemical and immunofluorescent staning.

分离胚鼠肠管，消化后接种于添加N2、B27和碱性成纤维细胞生长因子的DMEM/F12培养基，贴壁培养；连续传代后用血清促进GNCSCs分化；最后用免疫细胞化学方法染色鉴定。
