Day wouldn't have understood the concept of immortal cells or HLA markers coming from anyone, accent or not - he'd only gone to school for four years of his life, and he'd never studied science. The only kind of cell he'd heard of was the kind Zakariyya was living in out at Hagerstown. So he did what he'd always done when he didn't understand something a doctor said: he nodded and said yes. ~ Rebecca Skloot
C Hela Nedir quotes by Rebecca Skloot
Ultimately the judge threw Moore's suit out of court, saying he had no case. Ironically, in his decision, the judge cited the HeLa cell line as a precedent for what happened with the Mo cell line. The fact that no one had sued over the growth or ownership of the HeLa cell line, he said, illustrated that patients didn't mind when doctors took their cells and turned them into commercial products. The judge believed Moore was unusual in his objections. But in fact, he was simply the first to realize there was something potentially objectionable going on. ~ Rebecca Skloot
C Hela Nedir quotes by Rebecca Skloot
They also knew that there was a string of DNA at the end of each chromosome called a telomere, which shortened a tiny bit each time a cell divided, like time ticking off a clock. As normal cells go through life, their telomeres shorten with each division until they're almost gone. Then they stop dividing and begin to die. This process correlates with the age of a person: the older we are, the shorter our telomeres, and the fewer times our cells have left to divide before they die. By the early nineties, a scientist at Yale had used HeLa to discover that human cancer cells contain an enzyme called telomerase that rebuilds their telomeres. The presence of telomerase meant cells could keep regenerating their telomeres indefinitely. This explained the mechanics of HeLa's immortality: telomerase constantly rewound the ticking clock at the end of Henrietta's chromosomes so they never grew old and never died. ~ Rebecca Skloot
C Hela Nedir quotes by Rebecca Skloot
Henrietta's were different: they reproduced an entire generation every twenty-four hours, and they never stopped. They became the first immortal human cells ever grown in a laboratory. ~ Rebecca Skloot
C Hela Nedir quotes by Rebecca Skloot
The more comfortable you become with sharing your feelings, the more powerful you become. ~ Tamar Hela
C Hela Nedir quotes by Tamar Hela
At that point, more than 15,000 women were dying each year from cervical cancer. The Pap smear had the potential to decrease that death rate by 70 percent or more, but there were two things standing in its way: first, many women - like Henrietta - simply didn't get the test; and, second, even when they did, few doctors knew how to interpret the results accurately, because they didn't know what various stages of cervical cancer looked like under a microscope. Some mistook cervical infections for cancer and removed a woman's entire reproductive tract when all she needed was antibiotics. Others mistook malignant changes for infection, sending women home with antibiotics only to have them return later, dying from metastasized cancer. And even when doctors correctly diagnosed precancerous changes, they often didn't know how those changes should be treated. ~ Rebecca Skloot
C Hela Nedir quotes by Rebecca Skloot
Everyone in the audience knew what that meant. On top of saying they'd possibly wasted more than a decade and millions of research dollars, Gartler was also suggesting that spontaneous transformation - one of the most celebrated prospects for finding a cure for cancer - might not exist. Normal cells didn't spontaneously become cancerous, he said; they were simply taken over by HeLa. ~ Rebecca Skloot
C Hela Nedir quotes by Rebecca Skloot
Black scientists and technicians, many of them women, used cells from a black woman to help save the lives of millions of Americans, most of them white. And they did so on the same campus - and at the very same time - that state officials were conducting the infamous Tuskegee syphilis studies. ~ Rebecca Skloot
C Hela Nedir quotes by Rebecca Skloot
The American Type Culture Collection - a nonprofit whose funds go mainly toward maintaining and providing pure cultures for science - has been selling HeLa since the sixties. When this book went to press, their price per vial was $256. The ATCC won't reveal how much money it brings in from HeLa sales each year, but since HeLa is one of the most popular cell lines in the world, that number is surely significant. ~ Rebecca Skloot
C Hela Nedir quotes by Rebecca Skloot
Soon after Harris's HeLa-chicken study, a pair of researchers at New York University discovered that human-mouse hybrids lost their human chromosomes over time, leaving only the mouse chromosomes. This allowed scientists to begin mapping human genes to specific chromosomes by tracking the order in which genetic traits vanished. If a chromosome disappeared and production of a certain enzyme stopped, researchers knew the gene for that enzyme must be on the most recently vanished chromosome. Scientists in laboratories throughout North America and Europe began fusing cells and using them to map genetic traits to specific chromosomes, creating a precursor to the human genome map we have today. ~ Rebecca Skloot
C Hela Nedir quotes by Rebecca Skloot
I am Hel," she agreed. "Sometimes called Hela, though most mortals dare not speak my name at all. No jokes, Magnus Chase? Who the Hel are you? What the Hel do you want? You look Hela bad. I was expecting more bravado. ~ Rick Riordan
