What were HeLa cells used for?
HeLa cells are used by scientists to develop a cancer research method that tests whether a cell line is cancerous or not. This method proves so reliable that scientists use it to this day. HeLa cells are taken aboard some of the very first capsules used to explore outer space.
What did the HeLa cells help cure?
Over the past several decades, this cell line has contributed to many medical breakthroughs, from research on the effects of zero gravity in outer space and the development of the polio vaccine, to the study of leukemia, the AIDS virus and cancer worldwide.
What is special about Henrietta Lacks cells?
Henrietta Lacks and her “immortal” cells have been a fixture in the medical research community for decades: They helped develop the polio vaccine in the 1950s; they traveled to space to see how cells react in zero gravity; they even aided in producing a vaccine and reducing HPV infections—and subsequently instances of …
How old are HeLa cells?
It is the oldest and most commonly used human cell line. The line is derived from cervical cancer cells taken on February 8, 1951, from Henrietta Lacks, a 31-year-old African-American mother of five, who died of cancer on October 4, 1951.
Who Deborah Lacks?
Daughter of Henrietta Lacks, the African-American woman whose cancer cells source “HeLa” became the first immortalized and most important cell line in medical research. Deborah was portrayed by Oprah Winfrey in The Immortal Life of Henrietta Lacks (2017).
What was wrong with Deborah Lacks?
Winfrey stars in the film as Deborah Lacks, a daughter of the Turners Station resident whose cells were taken before she died of cervical cancer in 1951. The film follows her search to find out about her mother’s life.
Do patients own their tissues once they leave their body and do they have the right to control what is done with their tissues?
The foregoing cases demonstrate that, while individuals have the right to donate bodily tissues for research purposes, the right to own and control use of donated tissues vanishes once those tissues leave the body.
Should cells and tissues be used without consent?
Potential commercial applications must be disclosed to the patient before a profit is realized on products developed from biological materials. Human tissue and its products may not be used for commercial purposes without the informed consent of the patient who provided the original cellular material.
Do you own your own cells?
Individuals often give up their ownership rights, without even realizing it, when they agree to the terms and conditions on social media platforms or some apps. And court cases like Moore v. Regents of University of California (1990) have ruled that an individual does not actually own their own biological cells.
Is your DNA your property?
The interpretation of the courts is that once the DNA/tissue leaves the body, it is no longer the property of the individual. The courts seem to be relying on the informed consent contracts that patients sign prior to any procedure, which establishes clear guidelines for the future ownership of said materials.
Do researchers need consent to take and use cells from a person?
Researchers today follow a much stricter standard than what was in place in Henrietta Lacks’ day, requiring them to get a patient’s informed consent before taking identifiable samples to use in research. Once researchers have consent, they can use those samples, so long as they protect the patient’s privacy.
Do we own our bodily tissues?
However, when it comes to our tissues, our rights are less clear. However, while our society holds sacred an individual’s right in his/her body, the same rights are not recognized for an individual’s tissues. Once tissues or cells are removed from our bodies, they are no longer afforded the same protection.
Who owns these tissue samples do individuals own their own tissue samples?
In general, individuals do not own their tissue samples. No one really knows for sure who “owns” the samples, though research institutes, universities, and companies tend to hold them right now.
What is the controversy surrounding HeLa cells?
In Nature, Collins and Hudson pointed out that the genome of HeLa cells is not identical to Lacks’ original genome. The cells carry the changes that made them cancerous, and have undergone further changes over the time they have spent in cell cultures.
Is it ethical to take a biomedical sample from a patient to use for research without said patient’s informed consent?
Currently, scientists are allowed to use leftover tissues from blood tests, surgeries, and biopsies for research without patients’ permission if the patient’s identity is removed.
