因为这些嵌合体 仍然可以从正常细胞中产生血液,我们能够在适当的生物学背景下研究突变细胞。 Because these chimaeras could still make blood from their normal cells, we were able to study the mutant cells in their proper biological context.”. 这一方法同样降低了混合编辑和未编辑细胞的胚胎(这种胚胎也被称为嵌合体 )数目。 The approach also lowered the number of embryos containing a mixture of edited and unedited cells(these embryos are called mosaics ). 换句话说,他们是嵌合体 ,即两具身体的融合,这种现象可能发生在许多器官中,包括大脑。 They are, in other words, a chimera - a fusion of two bodies- and it may occur in many organs, including the brain. 这样,在嵌合体 中各个组成成分保持它们的特性,但在生长点处以一定的形式排列。 Thus in a chimera the components maintain their identity but are arranged in a definite pattern at the growing point. 相比之下,人与动物的嵌合体 包含了人类细胞与动物细胞的混合物。 A human-animal chimera contains a mixture of human cells and animals cells.
我也有同样的担忧,”Ross说,为此研究团队正在关注嵌合体 中人类细胞的最终发育方向。 I have the same concerns,” said Ross, noting that the team is looking at where the human cells end up in the chimera . 我也有同样的担忧,”Ross说,为此研究团队正在关注嵌合体 中人类细胞的最终发育方向。 I have the same concerns,” said Ross, adding that the team are looking at where the human cells end up in the chimera . 我说的当然是极端的情况,但是如果在15到20年前,光是把这些嵌合体 胚胎造出来就已经是‘极端的情况'了。 I am coming up with extreme scenarios, but just making these chimeric embryos 15 or 20 years ago was considered an extreme scenario.". 在新的研究中,Conejo-Garcia带领的团队开发出改良版CAR技术,称为嵌合体 内分泌受体表达T细胞(CER-T)。 In the new study, the team led by Conejo-Garcia developed a modified version of the CAR technology, called chimeric endocrine receptor-expressing T-cells(CER-T). 发表在8月10日Cell上的新方法将允许任何研究人员在脊椎动物模型中诱导多谱系基因嵌合体 ,如小鼠和斑马鱼。 The new methods, published today in Cell, will allow any researcher to induce multispectral genetic mosaics in vertebrate models such as mice and zebrafish. 最近,他在2017年发表了一项关于2.8亿年前嵌合体 化石的研究,该研究为这些鲨鱼状鱼类的早期发展提供了线索; Most recently, he published a 2017 study about a 280 million-year-old fossil of a chimaera , which led light on the early development of these shark-like fish; 相反,他们由如此多的成员组成,以至于他们的意图似乎是塑造一个嵌合体 或怪物,而不是创造一个比例良好的形象。 For they are generally made up of so many limbs that they seem intended rather to form a chimera or monster than a well-proportioned figure. More than 150 of the embryos developed into chimaeras ; Human chimeras do exist naturally, but they are still 100 percent human. 毕竟,她确实发现嵌合体 生物结合了两种物种的不同性格。 After all, she found that her chimeras shared the temperaments of both species. 斯坦福大学干细胞生物学家HiromitsuNakauchi于今年开始进行人羊嵌合体 的研究。 Hiromitsu Nakauchi, a stem-cell biologist at Stanford University, began trying to make human-sheep chimeras this year. 原则上,嵌合体 可以帮助研究人员更好地了解人类疾病和药物治疗的效果。 In principle, chimaeras could help researchers to better understand human illnesses and the effects of drug treatments.只仔猪中只有2只被确认是真正的嵌合体 ,即含有生物材料(即线粒体)。 Only two of the 10 piglets were confirmed to be true chimeras , that is, containing biological material(i.e. mitochondrial DNA) from both species. 吴军说:“在古代文明中,嵌合体 常和神灵联系在一起”,我们的祖先认为“嵌合体的形式可以守护人类”。 In ancient civilisations, chimaeras were associated with God,” he says, and our ancestors thought“the chimeric form can guard humans.”. 基因编辑可以帮助科学家优化人体细胞在另一物种体内生长的能力,允许转基因嵌合体 的创建。 Gene editing could help scientists to optimize human cells' ability to grow within another species, allowing the creation of transgenic chimaeras .
