| 摘 要： | 尝试建立一种简便有效的成年小鼠精原干细胞分离培养及扩增的方法。从单只成年小鼠的睾丸中经过两步酶消化法分离精原干细胞,并在去除间质细胞、纯化后的支持细胞饲养层上培养与扩增,获得稳定增殖的精原干细胞系。此方法可显著提高建系成功率,保证细胞系的单一基因型,显著降低体外培养精原干细胞的成本。为成体基因来源的转基因动物的制作和疾病模型的建立提供技术支持。

| Abstract: | In our study, we established a convenient and effective method for isolating and propagating the adult spermatogonial stem cells in vitro. We isolated the spermatogonial stem cells from the testes of one adult KM mouse by two-step digestion, and then cultured the cells on the purified Sertoli cells treated with mitomycin-C, eventually we established the stable adult spermatogonial stem cell lines. Our study increased the efficiency of cell line establishment prominently, guaranteed to achieve the single genotype cell line, and reduced the cost of culturing adult male germline stem cells in vitro. This method provided the foundation for producing the transgenic animals and disease models derived from adult genotype. |
