结论
我们已经提供了一个视频将告诉您,如何隔离,推导,文化10.5-11.5 DPC小鼠胚胎性腺脊的胚胎生殖细胞。胚胎生发细胞系的重现性隔离和长期的文化,提供了一个研究早期胚胎发育,遗传和表观遗传的生发模式,性腺形成的关键基础,在配子发生在男性和女性胚胎发育过程中,周围脏器的环境影响确定的途径,导致癌症和不育症。

Thank you very much to Harold Moreno-Ortiz ,Clara Esteban-Perez and other authors for making this video. Thanks a lot to "Jove" for giving such a wonderful platform to share those experiments which are other wise very complicated in text articles.
