这部电影的协议,旨在帮助学习核转移。

Abstract

核移植到未受精的卵母细胞可以分化的细胞恢复发展潜力。这表明,底层的发育,分化和老化的过程,而不是遗传过程的后生。这些过程的可逆性打开令人兴奋的观点,在基础研究和在更遥远的未来,在再生医学。在小鼠胚胎干细胞可以从克隆胚胎植入前胚胎。这种胚胎干细胞会引起成人的有机体的所有细胞类型的能力。更重要的是,这些细胞是基因完全相同的捐助。如果适用于人类,这将允许从病人的干细胞的推导。然后将这些细胞可以分化成病人受影响的细胞类型,并研究在体外,或用来替换损坏或丢失的细胞。在小鼠核移植的研究仍然是重要的,因为它可以告知我们有关核重编程的原则。这部电影和所附议定书的目的是帮助学习在小鼠核移植,这种方法最初教授柳町(和歌山等,1998)集团开发的。

Protocol

准备工作: 一个超数排卵和胚胎培养microdrop的详细描述,可以发现其他地方的2。 准备好与胚胎培养基(如KSOM,Chemicon公司)microdrops培养皿。盖与矿物油(矿物油批次应与胚胎培养的兼容性测试)。平衡在37℃空气中加5%的CO 2中的C。 (热电子3110水套式孵化器或同等) 卵母细胞的隔离准备一道菜:HEPES广场滴缓冲CZB和…
