Biologists in Japan have cloned 581 mice from one original donor mouse, Livescience reported. The scientists made the mice over 25 generations of cloning; that is, from making clones from clones from clones, 25 times over.
根据Livescience的报道,日本生物学家用一只小鼠的基因供体克隆出581只小鼠。这些科学家们克隆了25代小鼠,即:用克隆鼠克隆新的小鼠,一共克隆了25次。
They could probably make animal clones indefinitely, the research team wrote in a paper published last week in the journal Cell Stem Cell.
研究团队在上周发表在《干细胞》期刊中的论文称,他们很有可能会让动物无休无止地克隆下去。
Really. Check out the last sentence of their abstract: "Our results show that repeated iterative recloning is possible and suggest that, with adequately efficient techniques, it may be possible to reclone animals indefinitely."
是这样吗?我们来看看论文摘要的最后一句话:“我们的研究结果证明多代克隆是可能实现的。如果技术到位,那么克隆出无穷多代的动物都是可能的。”
The 581 cloned mice were made using an improved version of somatic cell nuclear transfer, the technique that created Dolly the cloned sheep in 1996.
这581只小鼠是用改进后的体细胞克隆技术克隆得到的,这一技术最早是在1996年克隆多莉时发明的。
