摘要

大多数科学和医学发现都伴随着描述新过程的新术语。尽管这给社会带来了不断学习新词汇的负担,但新术语阐明了新兴技术的社会影响需要重新解读。然而,这种普遍做法的一个显著例外是,未能开发出新的术语来描述对哺乳动物卵子的新要求。哺乳动物的卵子大约是体细胞大小的250倍,精子头大小的4000倍,是一种高度特化的细胞,它储存了大量的酶和其他分子,使其能够完全重塑引入的染色体

What is an embryo?
Most scientific and medical discoveries are accompanied by new terms to describe the new processes. Although this imposes the burden on society of continually learning a new lexicon, new terminology clarifies that the societal impact of emerging technologies needs to be newly interpreted. A notable exception to this general practice, however, has been the failure to develop new terms to describe the new demands placed on mammalian eggs. Approximately 250 times the size of a somatic cell, and 4,000 times the size of a sperm head, the mammalian egg is a highly specialized cell which has stockpiled a collection of enzymes and other molecules that empower it to completely remodel the chromosomes brought in
