During her treatment at the hospital, samples of cancerous tissue were taken from her cervix. These cells went on to become the immortal cell line known as HeLa. Over the following years, HeLa cells have enabled scientists around the world to make great leaps in science and medicine. This list highlights five of these remarkable contributions. InHeoa cells were found to be both susceptible to, but not killed by polio, making them an ideal source of host cells.

O n 4 October , a young black woman named Henrietta Lacks died of cervical cancer in Baltimore’s Johns Hopkins hospital. The mother of five children, Henrietta was 31 and, although poor, was remembered as being strikingly pretty. Apart from that, there seemed to be nothing special about her life. But in death Henrietta was transformed. Cells removed from her body — without her family’s permission — were subsequently used by doctors to revolutionise medicine. By mixing them with special plasma, they succeeded in growing her tumour cells in the laboratory. It was the first time that a human cell line had survived outside the body. More than 50 million tonnes of Henrietta’s cells have been grown since she died, while their use is acknowledged in more than 60, scientific papers, with 10 new studies added to the list every day. Yet Henrietta’s body lies in an unmarked grave, while her children have revealed they did not learn for more than 20 years that their mother’s cells were still alive and had been used to create an entire branch of medical science. It is a disturbing story that has just been propelled into the US bestseller lists thanks to science writer Rebecca Skloot. Skloot has taken the case of Henrietta Lacks and her cancer cells and used it to fashion a penetrating analysis of the behaviour of modern doctors while at the same time treating the reader to a moving biography of Henrietta and her children.

The connected pairs of HeLa cells in this slide are individual cells dividing to form two new cells in a process called mitosis. Murti hide caption. The cell’s power lies in its immortality, or ability to be kept alive and grown indefinitely. But few people know that the cells originally belonged to a poor Southern tobacco farmer named Henrietta Lacks who was being treated for cervical cancer at Johns Hopkins University when her doctor reserved samples of her body tissue for his research. Lacks died of cancer 60 years ago, but her cells — taken without her knowledge or consent — are still alive today. Read An Excerpt. Skloot says that 60 years ago, doctors could never have known what their experiments would lead to. What’s more, Skloot says the treatment Lacks received for her cervical cancer included radiation and chemotherapy that rendered her infertile, which doctors never warned her about. She describes the medical standard of time as «benevolent deception. But despite Lacks’ status as a poor African-American woman, Skloot says her treatment on the public ward at Johns Hopkins was top-of-the-line. Even so, Skloot says the country’s history of segregation in medical care meant that African-American patients were often treated as second-class citizens. Skloot says those conditions likely applied to Lacks as well.
Explore HeLa’s impact on research over the past six decades
At first glance, it seems unthinkable that Lacks’ family didn’t know about HeLa cells, but nobody ever told them. Gey and the researchers at Johns Hopkins weren’t legally bound to do so — it was routine to take samples of blood , cells and tissues from patients without telling them or getting their consent. Nobody could’ve known then what would become of Lacks’ cells. It wasn’t until the early s that Lacks’ family got an inkling of Henrietta’s legacy. Her husband, Day, got a call from someone at Johns Hopkins hospital that confused him — the person was telling him that his wife was still alive but as cells in a lab. He believed the researcher was telling him that they needed to test her children to find out if they also had cancer. The Lacks children submitted to testing but were never contacted about the results. Author Rebecca Skloot, who published «The Immortal Life of Henrietta Lacks» in , states that the family was misled about the research, which was not done to help them but to better understand Henrietta’s genetics. Skloot befriended members of Lacks’ family, including her daughter, Deborah Lacks-Pullam. Gey and Johns Hopkins didn’t profit off HeLa, but the cells and related products have been sold since

Over the past six decades, huge medical advances have sprung from the cells of Henrietta Lacks, a poor, African-American mother of five who died in of cervical cancer. But Lacks never agreed that the cells from a biopsy before her death taken could be used for research. For years, her own family had no idea that her cells were still alive in petri dishes in scientists’ labs. They eventually learned they had fueled a line called HeLa cells, which have generated billions of dollars, but they didn’t realize until this spring that her genome had been sequenced and made public for anyone to see. On Tuesday, the National Institute of Health announced it was, at long last, making good with Lacks’ family. Under a new agreement, Lack’s genome data will be accessible only to those who apply for and are granted permission. Additionally, any researcher who uses that data will be asked to include an acknowledgement to the Lacks family in their publications. The new understanding between the NIH and the Lacks family does not include any financial compensation for the family. But this is a moral and ethical victory for a family long excluded from any acknowledgment and involvement in genetic research their matriarch made possible. It took more than 60 years, but ethics has finally caught up to a particularly fast-moving area of science: taking tissue samples for genetic research. Thanks to the efforts of a dogged journalist, some very thoughtful science leaders in Europe and the U. The news of the day is that the analysis of the genetic makeup of HeLa cells, the most useful cells used in all of biomedical research, has been completed. But the real news here is that medicine and science have finally done right by the person from whom those cells were taken—Henrietta Lacks.

The HeLa cells survived, thrived, and multiplied outside her body, so much so that they have been in continual use in labs around the world for 65 years, even though Lacks herself succumbed to cancer in Here are just a few of them. In the early s, German virologist Harald zur Hausen found that HeLa cells contained multiple copies of human papillomavirus 18 HPV , a strain of HPV later found to cause the type of cervical cancer that killed Lacks. HPV was found to be one of the most dangerous strains of the virus, inserting its DNA into normal cells and forcing them to produce proteins that ultimately lead to cancer. Over time that means that the chromosomes become slightly shorter, which is thought to be a driver of cell aging. Then, in , Yale scientist Gregg Morin used HeLa cells to isolate the same enzyme in human cells for the first time. Morin hypothesized that this enzyme, found in cancer cells, was also how embryonic cells were able to rapidly divide at the beginning of life.

HeLa cells helped make the vaccine available sooner. In the early s, Jonas Salk had already figured out how the vaccine worked; the problem was testing it. Ordinarily, Salk would have tested the vaccine on cells from monkeys. But monkeys and their cells rid expensive, especially considering that testing the vaccine actually killed the cells in the process.
No such cells existed until researchers found HeLa cells. Not only were these cells more susceptible to the virus than the cells scientists previously used, the fast-growing cells were nearly impossible to kill.
Scientists at the Tuskegee Institute built a factory to reproduce HeLa cells, allowing Salk to successfully test the vaccine, which in the last 60 years has effectively eliminated polio in most of the countries of the world. More recently, microbiologists found that Zika cannot multiply in HeLa cells. Digging further into why that is could produce a new treatment or vaccine for the disease.
About or I was part of joney because of some puzzling symptoms. Back at high school the next day I excitedly told a nurse about the article. She said the cells would not outlive the patient for several decades. I hope that nurse lived long enough to see these results made available to the general public and then thought about how she ridiculed me.

My Immortal Cells
The gift of life is surely the greatest gift of all. So how could the story of a remarkable woman who gave that gift over and over again have been overlooked for so long? Here’s Jim Axelrod now to set the record straight:. She was a poor, African-American tobacco farmer, a mother of five children, who died of cervical cancer when she was She was also, says Rebecca Skloot, one of the most important unknown figures in medicine, «and she had no idea. Skloot, a professor at the University of Memphis, devoted 10 years to telling her story, writing the current bestseller, «The Immortal Life of Henrietta Lacks. The story starts near the end of Henrietta’s life: in the great-granddaughter of slaves was being treated for cervical cancer at Johns Hopkins Hospital in Baltimore. Without her knowing, and unrelated to her treatment, doctors took some of her cells for research. By the late s scientists were on the brink of a golden age of medicine, Jonas Salk was racing to develop the polio vaccine, but his work — and that of countless others — was hampered because they lacked a critical tool: human cells for testing. Scientists had been trying for years to keep human cells alive in the lab, but none of them lasted very long, until Henrietta Lacks showed up at Hopkins. And hers just took off. For the first time in history, human cells could be grown and infinitely replicated, outside the body. Henrietta Lacks died in Octoberjust 8 months after seeking help at Hopkins.
