HeLa Cells in Medical Research and Bioethics
Used in scientific research, the HeLa cells are known to be a type of immortal, tissue cultured cell line. A cell line is a group of cells taken from a person and used for scientific research (science.howstuffworks.com). When a cell type is known to be immortal, it refers to the cells being able to divide an indefinite amount of times, when cell survival conditions are met in a laboratory. The first human cell line to survive in a test tube, or in vitro, was the HeLa cells (science.howstuffworks.com). These cells were taken from a tissue of a tumor of a woman with cervical cancer back in the 1950s. Her name was Henrietta Lacks. There have been many advances in medicine and biomedical research because of her cells.
An African-American woman, Henrietta Lacks lived in Virginia, where she grew tobacco (www.smithsonianmag.com). At the age of thirty, she developed cancer. She had a husband and five children, whom she left orphaned when she died at thirty-one (www.esciencecentral.org). She received aggressive treatment, for that time, at Johns Hopkins Hospital in Maryland, which was one of the only hospitals willing to accept African-American patients. While undergoing treatments, a physician removed a small tissue sample of a tumor and sent it for testing, without her knowledge. It was not that uncommon for things such as that to occur back then. While she may have signed and acknowledged her treatments, the removal of that tissue was not part of it. Once a sample had been removed from a patient, whether by surgery or biopsy, it was no longer considered to belong to the patient, and could be used and...

The family first heard that Henrietta’s cells were alive and being sent around the world, twenty-two years after Henrietta’s death. After discovering that Henrietta’s cells were in circulation, the family began to blame John Hopkins for taking Henrietta’s cells without permission and commercializing the cells to make multi-million dollar industry, while her family was living in poverty without health insurance. The John Hopkins Hospital has made various statements stating that the hospital never received funds for the HeLa cells specifying that Gey donated all of his HeLa cells samples to fellow researchers. Therefore, the sole benefactors of the HeLa cells profits are the biotechnology companies, which sell vials of HeLa cells for up to ten thousand
In the book, The Immortal Life of Henrietta Lacks, by Rebecca Skloot, the author highlights the scientific advances of HeLa cells, as well as the personal setbacks of Henrietta Lacks’ family. HeLa is a commonly used cell line in laboratories worldwide and is so often referred to as “the cell line that changed modern science”. This line of immortal cells has helped advance science in ways beyond compare. HeLa has allowed cell testing, cell cloning, and the discovery of various vaccines, including the HPV vaccine. While HeLa has done wonders in the medical field, it has caused unrepairable damage among the Lacks family.
Henrietta’s cells were being inaugurated with space travel, infused into rat cells, and even being used to make infertile hens fertile again. However, these are only a few of the many accomplishments that Henrietta’s immortal cells made possible: “The National Cancer Institute was using various cells, including HeLa, to screen more than thirty thousand chemicals and plant extracts, which would yield several of today’s most widely used and effective chemotherapy drugs, including Vincristine and Taxol,”(pg.139). This example of logos from the text again shows just how important these Henrietta’s cells were to the future developments in
Although it may seem impossible that the human who spawned this cell line would go unrecognized, this was exactly the case with Henrietta Lacks. In fact, her name was purposely altered in many publications to Helen Lake, Helen Lane or some variation of the sort, in order to hide her identity. As crazy as it may seem, Even Henrietta 's ' own family were unaware that the cells were taken from her and were being used in labs across the globe. The purposeful alteration of the name Henrietta Lacks is a sort of symbolic violence; a symptom of the structural violence which led Henrietta to Johns Hopkins hospital in the first place. By altering her name, and referring to her cell line as "HeLa," the scientific community effectively reduced the memory and image of Henrietta to something less than human. Scientists began to think of HeLa as something which was only a cell line, not as cells which had once been attached to a human being, with a life of her
The Immortal Life of Henrietta Lacks tells the story of Henrietta Lacks. In the early 1951 Henrietta discovered a hard lump on the left of the entrance of her cervix, after having unexpected vaginal bleeding. She visited the Johns Hopkins hospital in East Baltimore, which was the only hospital in their area where black patients were treated. The gynecologist, Howard Jones, indeed discovers a tumor on her cervix, which he takes a biopsy off to sent it to the lab for diagnosis. In February 1951 Henrietta was called by Dr. Jones to tell about the biopsy results: “Epidermoid carcinoma of the cervix, Stage I”, in other words, she was diagnosed with cervical cancer. Before her first radium treatment, surgeon dr. Wharton removed a sample of her cervix tumor and a sample of her healthy cervix tissue and gave this tissue to dr. George Gey, who had been trying to grow cells in his lab for years. In the meantime that Henrietta was recovering from her first treatment with radium, her cells were growing in George Gey’s lab. This all happened without the permission and the informing of Henrietta Lacks. The cells started growing in a unbelievable fast way, they doubled every 24 hours, Henrietta’s cells didn’t seem to stop growing. Henrietta’s cancer cell grew twenty times as fast as her normal healthy cells, which eventually also died a couple of days after they started growing. The first immortal human cells were grown, which was a big breakthrough in science. The HeLa cells were spread throughout the scientific world. They were used for major breakthroughs in science, for example the developing of the polio vaccine. The HeLa-cells caused a revolution in the scientific world, while Henrietta Lacks, who died Octob...
Although she was taken from the world too soon, Henrietta Lacks was a warm hearted woman, and though unbeknownst to her, she would pave the way for the medical field and greatly expand our understanding of one of the nation’s greatest killers; cancer. In 1951 people did not talk about cancer lightly; cancer was a very touchy subject, especially for those who knew they couldn’t receive treatment once they had been diagnosed. When Lacks went to the hospital because of a “knot on her womb” she never thought that it would grow into a full fledge tumor that would end up taking her life. Henrietta lived a simple yet happy life which consisted of working on the farm, loving her husband, and raising children, and she was not going to ruin the lifestyle she knew so well by telling her family that she had cancer; it was just unheard of.
Rebecca Skloot’s novel, The Immortal Life of Henrietta Lacks, depicts the violation of medical ethics from the patient and researcher perspectives specifically when race, poverty, and lack of medical education are factors. The novel takes place in the southern United States in 1951. Henrietta Lacks is born in a poor rural town, Clover, but eventually moves to urban Turner Station. She was diagnosed and treated for cervical cancer at Johns Hopkins hospital where cells was unknowingly taken from her and used for scientific research. Rebecca Skloot describes this when she writes, “But first—though no one had told Henrietta that TeLinde was collecting sample or asked she wanted to be a donor—Wharton picked up a sharp knife and shaved two dime-sized pieces of tissue from Henrietta's cervix: one from her tumor, and one from the healthy cervical tissue nearby. Then he placed the samples in a glass dish” (33). The simple act of taking cells, which the physicians did not even think twice about, caused decades
The book The Immortal Life of Henrietta Lacks by Rebecca Skloot, was a nonfiction story about the life of Henrietta Lacks, who died of cervical cancer in 1951. Henrietta did not know that her doctor took a sample of her cancer cells a few months before she died. “Henrietta cells that called HeLa were the first immortal human cells ever grown in a laboratory” (Skloot 22). In fact, the cells from her cervix are the most important advances in medical research. Rebecca was interested to write this story because she was anxious with the story of HeLa cells. When she was in biology class, her professor named Donald Defler gave a lecture about cells. Defler tells the story about Henrietta Lacks and HeLa cells. However, the professor ended his lecture when he said that Henrietta Lacks was a black woman. In this book, Rebecca wants to tell the truth about the story of Henrietta Lacks during her medical process and the rights for Henrietta’s family after she died.
The first of four views in the book is Henrietta’s life and family. Henrietta was a black woman born August 1, 1920 in Roanoke, Virginia. She had her first child when she was 14 with her cousin Day. She then has a baby girl and then married when she was 18 on April 10, 1941. It all started after Henrietta’s fifth child was born when Henrietta said that she felt a knot inside of her womb. Her friends said it was just her baby, but Henrietta knew it wasn’t. She decided to go to the hospital and had a biopsy taken of a lump the size of a nickel in her cervix. She ended up being right; finding out that she had cervical cancer. Back then radium was used to treat cancer so they put a radium tube in and sent her home. While all of this was going on, Henrietta took her mentally challenged daughter to a mental institute hoping she’ll have a better life with more care. Henrietta then started receiving spot radiation treatments to try to get rid of the cancer. Her skin started to char af...
In the 1960s the HeLa cells were everywhere. In the 1960s the scientist wondered since the cells grew so fast and lived on earth so well if they would live in space. They got the idea to send the Hela cells to space. They sent several vials into space by the Discoverer XVII when it went. They discovered that when the HeLa cells went to space they became more powerful and divided faster every time they went to space. Several years later in 1965 they took equal amounts from the HeLa cells and cells from a mouse. The scientists done this to study to see what the genes would do. Harris also took HeLa cells and chicken cells, but they discovered they couldn’t reproduce.
The novel The Immortal Life of Henrietta Lacks, by author Rebecca Skloot is about a black woman whose cells were used by doctors to study medicine without her knowledge or her permission. Rebecca Skloot first heard of Henrietta Lacks when she was 16-years-old in her college biology class. Her professor, Donald Defler, mentioned Henrietta briefly during his lesson about cells. Defler talked about how Henrietta’s cells helped scientists learn all they know about cell and cell culture today, and allowed them to develop disease-fighting drugs to combat herpes, leukemias, influenza, hemophilia and Parkinson’s disease. Although Defler did acknowledge the fact that it was Henrietta’s cells who helped change the future of medicine, all Defler added was that she was a black woman. Skloot was unsatisfied with this information and she wanted to know more about Henrietta Lacks, such as “Where was she from?... Did she know how important her cells were? Did she have any children?” (Skloot 4). The problem was, though, that no one cared to find out anything about the person whose cells were famous all over the world. Most people, in fact, did not even realize that her name was Henrietta Lacks, and not Helen Lane. All people knew about this woman was that her cancerous cells were referred to as HeLa cells. Thus, Skloot’s purpose was to inform people around the world about the life of the woman whose
Henrietta Lacks was a poor woman with middle school education have made the greatest medical contributions. Henrietta lacks had made one of the greatest medical contribution because her cells were growing and dividing rapidly. Henrietta Lacks cells were taken from a cervical-cancer biopsy. The HeLa cells (Henrietta Lacks cells) help accomplish amazing things in the medical fields. The HeLa cells had helped accomplish advancement in medicine. The Hela cells that were taken from her tumor when she was undergoing surgery have been accountable of the medical advances. The polio vaccine, chemotherapy, cloning, gene mapping and IVF were the advancement in medicine. These health breakthroughs were possible because of Henrietta Lacks. The scientists
In conclusion, the Henrietta Lacks cells have lived longer outside of her body than actually in it. Henrietta went from a small farm in Virginia with little education, to battling cervical cancer, and going on to change how we look at science in her short life. There are many areas of her life and legacy that I could have gone into today such as race discrimination, moral ethics, and patients’ rights but I have chosen to just give a overview on the facts surrounding her . Today, there is much acclaim for a woman who will never know the impact she had had on science. Her family is aware however and is working to make sure that the world knows about Henrietta Lacks. While her life may have been short her death may have changed the course of science. So again, can your cells change medical history? The answer now should be maybe.

Although humans have altered the genomes of species for thousands of years through artificial selection and other non-scientific means, the field of genetic engineering as we now know it did not begin until 1944 when DNA was first identified as the carrier of genetic information by Oswald Avery Colin McLeod and Maclyn McCarty (Stem Cell Research). In the following decades two more important discoveries occurred, first the 1953 discovery of the structure of DNA, by Watson and Crick, and next the 1973 discovery by Cohen and Boyer of a recombinant DNA technique which allowed the successful transfer of DNA into another organism. A year later Rudolf Jaenisch created the world’s first transgenic animal by introducing foreign DNA into a mouse embryo, an experiment that would set the stage for modern genetic engineering (Stem Cell Research). The commercialization of genetic engineering began largely in 1976 wh...
