| 摘 要： | 精原干细胞（spennatogonial stem cells，SSCs）是雄性动物体内能进行终生自我更新并能将亲代基因遗传给予子代的一类细胞。不同年龄段的小鼠有不同的建系方法。6-7d幼鼠，可以用差异贴壁或直接贴壁法；5-6周成年鼠，一般采用差异贴壁法；31周老年鼠，最好种于饲养层细胞上。通过对精原干细胞系的甲基化和特异基因分析以及睾丸体内移植验证分析，成功建立了具有功能的不同年龄段的小鼠精原干细胞系。

| Abstract: | Spermatogonial stem cells （SSCs） are a pool of cells which are capable of self-renewal and differentiation in male animals＇ whole-life. We established several SSC lines of mice at different ages using three methods. The results showed that two methods （difference adherence and direct adherence） could be used to establish SSCs in the 6-7 d little mice, but the SSCs from 5-6 weeks＇ mice were established only by the difference adherence. However, we did not get the SSCs lines of 31 weeks mice using the methods which were mentioned above other than culture on feeder cells. Finally, the functions of those SSCs were determined through analysis of spermatogonial stem cell lines methylation, specific genes expression and in vivo testis transplantation validation. |
