HeLa cells themselves actually have around 80 highly mutated chromosomes.

海拉细胞自己拥有大约八十条高度变异的染色体。

Telomerase, an enzyme that helps cancer cells evade destruction by repairing their DNA, was discovered first in HeLa cells.

端粒酶，这个酶会修复癌细胞的DNA, 避免癌细胞的死亡，在海拉细胞中被第一次发现。

Today, we examine the woman behind the notorious and immortal HeLa cells: Henrietta Lacks.

今天，我们来看看臭名昭著的不朽 HeLa 细胞背后的女人：Henrietta Lacks。

Gey was ecstatic the cells were growing " like crabgrass" and soon, among researchers, word was out about the amazing HeLa cells.

Gey 欣喜若狂，这些细胞“像马唐草一样”生长，很快，在研究人员中，关于惊人的 HeLa 细胞的消息就传开了。

Henrietta's HeLa cells helped doctors figure out - or understand - a lot about how cells grow and led to so many medical discoveries.

亨丽埃塔的" 海拉细胞" 帮医生们弄清楚——或者理解了很多东西——细胞的繁殖方式以及许多医学发现。

By the next morning to Mary's surprise, Henrietta's cells had divided, and in the days ahead, HeLa cells kept making copies of themselves.

令玛丽惊讶的是，第二天早上，海瑞塔的细胞已经分裂，在接下来的几天里，海拉细胞不断复制自己。

HeLa cells have even been put into space on missions with both Americans and Russians, were tested against an atomic bomb, and were the first human cells to be cloned.

海拉细胞甚至被送入太空，与美国人和俄罗斯人一起执行任务，接受了原子弹测试，是第一批被克隆的人类细胞。

No one, aside from the patient's doctors and lead researchers knew the origins of the HeLa cells — not her name, or anything else about her life.

除了病人的医生和主要研究人员，没有人知道 HeLa 细胞的起源——不知道她的名字，也不知道她生活中的任何其他事情。

The HeLa cells, named for the patient's first and last name, acted differently than other cells in the lab — they were hardier, and replicated at an amazing rate.

海拉细胞以病人的名字和姓氏命名，其作用不同于实验室中的其他细胞——它们更顽强，并以惊人的速度复制。

Named 'HeLa cells' after her initials, Henrietta Lacks' tissue helped make possible all sorts of medical breakthroughs, from the polio vaccine to cancer drugs, to HIV and IVF treatments.

组织中的细胞以她姓名的首字母被命名为" 海拉细胞" ，亨丽埃塔·拉克斯的这种组织帮助实现了各种医学突破，从小儿麻痹症疫苗到抗癌药物，再到艾滋病治疗和体外受精治疗。

While this groundbreaking biomedical research was taking place, only a handful of people could trace the HeLa cell line origins back to a poor, 31-year old black woman with cervical cancer.

当这一开创性的生物医学研究正在进行时，只有少数人能够将 HeLa 细胞系的起源追溯到一名患有宫颈癌的 31 岁贫困黑人妇女。

This resulted not only in new fertility treatments, but later in AIDS and cancer breakthroughs, which is why Rebecca refers to HeLa cells as a workhorse, meaning someone who does a lot of work.

这不仅带来了新的不孕治疗方法，而且后来使艾滋病和癌症方面也取得了突破，这就是为什么瑞贝卡将" 海拉细胞" 称为" 主力军" ，意思是完成大量工作的人。

Henrietta's HeLa cells helped doctors figure out, or understand, a lot about how cells grow and led to so many medical discoveries we might call them a workhorse, something which works extremely hard.

海里埃塔的 HeLa 细胞帮助医生们弄明白或理解了很多关于细胞生长的内容，并且催生了如此多的医学发现，我们可以把它们叫做老黄牛，指的是工作极其辛苦的事物。

A book published in 2010 by author Rebecca Skloot and a movie starring Oprah Winfrey has recently brought greater attention to the woman behind the " immortal" HeLa cells, raising ethical questions for the world to ponder.

作者丽贝卡·斯库洛特 2010 年出版的一本书和奥普拉·温弗瑞主演的一部电影最近引起了人们对“不朽”海拉细胞背后的女人的更多关注，引发了世界思考的伦理问题。
