Favorite Hela Cells Quotes

1. "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."

2. "Nelson-Rees had since been hired by the National Cancer Institute to help stop the contamination problem. He would become known as a vigilante who published "HeLa Hit Lists" in Science, listing any contaminated lines he found, along with the names of researchers who'd given him the cells. He didn't warn researchers when he found that their cells had been contaminated with HeLa; he just published their names, the equivalent of having a scarlet H pasted on your lab door."

3. "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."

4. "Since the Common Rule says that research subjects must be allowed to withdraw from research at any time, these experts have told me that, in theory, the Lacks family might be able to withdraw HeLa cells from all research worldwide. And in fact, there are precedents for such a case, including one in which a woman successfully had her father's DNA removed from a database in Iceland. Every researcher I've mentioned that idea to shudders at the thought of it."

5. "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."

How encouraging to remember that the Spirit of God is more powerful than the spirit of wickedness! As 1 John 4:4 reminds us, "You, dear children, are from God and have overcome them, because the one who is in you is greater than the one who is in the world."
