当一些科学家通过基因研究“克隆”出动物时,另一些科学家则千方百计试图通过基因研究来探寻人的生命极限,就是人究竟能活多长?100岁,150岁,甚至200岁? 探寻生命极限必须首先破译这样一个生命之谜:人为什么会衰老?其次才能研究推迟衰老的方法。对衰老问题的研究始于1961年,但在开始时,科学家一直为这一问题所困惑,即衰老是从哪一部分开始的,是细胞本身还是由细胞构成的较大的组织?为此科学家进行了下述实验:他们从胎儿组织中取来细胞并保存在
While some scientists “cloned” animals through genetic research, others tried every means to explore the limits of human life through genetic research, namely, how long can a person live - 100, 150, or even 200? We must first decipher the mystery of life: why people aging? Second, to study the method of delaying aging. The study of aging began in 1961, but at the outset scientists were puzzled by the question of where the senescence started, whether the cells themselves or the larger tissues made up of cells, for which scientists The following experiment: They fetched cells from fetal tissue and preserved them
