Who is the "Immortal" Women? It's Henrietta Lacks!

The story of Henrietta Lacks is quite tragic. Her life was cut short by cervical cancer but her legacy still lives on today. Henrietta Lacks became the immortal woman as it was her cells that gave birth to HeLa Cells. HeLa cells have become a laboratory staple and have contributed to a number of scientific breakthroughs in medicine, space exploration, and the polio vaccine. But who was Henrietta Lacks beyond the 'immortal women".

Who Was Henrietta Lacks?

Henrietta Lacks was born in 1920. She moved into an old slave quarters cabin with her grandfather and cousin at a young age after the death of her mother. Henrietta Lacks had two kids with her cousin, giving birth to her first child when she was 14. Henrietta Lacks would later marry her cousin in 1941.

She was a poor southern African-American tobacco farmer, not a scientist or a researcher, and barely had the means to provide for her family.

However, unknowingly, and without consent, Henrietta Lacks gave birth to a large part of modern medicine, changing the fields of microbiology and virology forever.

In early 1951, Henrietta Lacks was having intense pain, a knot in her womb, and bloody vaginal discharge. Unable to stand the pain any longer, she went to John Hopkins to see Dr. Howard Jones. He took a biopsy, found a tumor, and diagnosed her with cervical cancer. During this time, cancer was a terrible diagnosis to get. Even today, cervical cancer has an average 5-year survival rate of 66%.

Just over a week later, she came back to the hospital where Henrietta saw Dr. George Otto Gey and took another biopsy. These cells that Dr. George Otto Gey took would make Henrietta Lacks the “immortal” woman. This would forever change medicine, save countless lives, and fuel an ethical discussion that is still raging today.

The cells that Dr. Otto Gey took eventually became the HeLa cell line used in research. Her cells still live on today, but her body and soul passed on in late 1951 when cancer had metastasized throughout her body. Her family was not aware that science was still replicating her cells until 25 years after her death.

Think about that for a second. A piece of someone you knew, whose funeral you attended, who you had to say goodbye to is still a part of laboratories across the world. A piece of them is still living and will continue to live and will outlive you and me.

What Are HeLa Cells?

HeLa cells are known as the “immortal” cell line. When Gey took the sample from Henrietta, he noticed they were quite strange. He studied them, isolating the cells that had the best qualities.

HeLa cells are special because they continue to replicate and they easily survive in laboratory settings.

Once isolated, it was clear these cells were going to revolutionize modern medicine. A special unit of black scientists was created at the Tuskegee Institute in Alabama to produce the HeLa cells at the very same time the Tuskegee Study of Untreated Syphilis in the Negro Male” was happening.

It was estimated that at peak production, this unit was shipping some 20,000 tubes of HeLa cells a week. In the past 60 years, 50 million metric tons of HeLa Cells have been grown, which is ridiculous when you think of the weight of a single cell! To give you an idea, you lose about 500 million skin cells today….Do you feel lighter?

These cells have been used in research from cancer treatment, in vitro fertilization, gene mapping, radiation effects, and even cloning. They have even been shot into space and led the way to improved cell culture practices. But I know the real information you want to know is how does Henrietta Lacks and HeLa cells relate to microbiology!?!

HeLa Cells In Microbiology: A Vaccine Story

The answer lies in virology, specifically in the work of vaccines. Not so long ago, polio was a major debilitating and deadly disease of children in the US, causing paralysis and meningitis. The poliovirus can infect the spinal cord and render muscles too weak to even take a breath. In 1952, nearly 60,0000 children contracted the disease, 3,000 died and so many others were left paralyzed for life!

Today, in America and most of the world, polio is not so terrifying, thanks to the research by Jonas Salk and Henrietta's cells. Jonas Salk had developed the polio vaccine in the early 1950s, but he had no way of testing it. At the time, Rhesus Monkey cell lines could be used, but they were expensive and died easily when in contact with poliovirus. However, the HeLa cells were susceptible to the disease and did not die from the contact with the virus; they were also cheaper and from a human, making them ideal to test Salk’s vaccine on a large scale!

It took nearly a decade to develop and test the vaccine, but once he did, Salk became an American hero and by the 1960s Polio was nearly eradicated in the US. Polio is not fully eradicated today, with outbreaks still occurring in Pakistan, Afghanistan, Nigeria, and several other countries. To try to combat the virus, a vast polio eradication network featuring some 20 million medical heroes working tirelessly to wipe out the disease.

The current COVID-19 pandemic has, unfortunately, put a hold on these efforts. It’s estimated some 13.5 million children did not get vaccinated since the shutdown. Unfortunately, the shelf life of the vaccines is near their expiration date, and Trump's pullout from WHO drastically affects the funding for this effort. Many believe that Polio cases will surge in the post-pandemic era.

HeLa cells have launched virology into a new age, being involved in the research of several current viral infections including HIV, herpes, Zika, measles, mumps, and, of course, our current viral pandemic, COVID-19. Some of these have shown mild success, but none as much as polio.

However, there is one more microbiology success story that has stemmed from HeLa cells. Cervical cancer, which Henrietta Lacks died from, is often caused by a viral infection known as HPV. Henrietta Lacks was infected by a particularly virulent strain of virus known as HPV-18. In the 1980s, some thirty years after the cells were first isolated from Henrietta, Harald Zue Hausen linked HPV to cervical cancer. This discovery led to him receiving the Nobel Prize and the development of a vaccine that is now given to teenage girls to prevent HPV infection and subsequent cervical cancer. It’s estimated this vaccine will reduce deaths from cervical cancer by 70%!

So What's The Big Deal? The Ethical Dilemma Of HeLa Cells

What if I was to tell you, the last time you went to the doctors and had blood drawn, your doctor found something amazing such as your blood contained the cure for COVID-19!

The researchers then take your blood and develop a vaccine and the pandemic is over, that’s great! You helped cure the greatest pandemic of the 21st century so far!

The doctor, however, never acknowledged you or told you they were using your blood which was published and shared across the world. Furthermore, the researchers put a patent on it and made millions...

Meanwhile, you can’t get a decent doctor's visit or can afford medication for yourself and your family. How would that make you feel?

Then think, 60 years later, you're dead, but your cells live on continuing to do great things for medicine, but your family is still not being taken care of. Henrietta Lacks did not do the research nor discovered the polio vaccine, but her cells changed the world.

Today there are some 11,000 patents involving HeLa cells and as the age of the genome rages on, the ethical concerns on consent and privacy are just beginning.

There is a fine line between patient privacy, consent, and compensation against societal benefits. Even with societal benefits, such as polio and HPV vaccine, someone is benefitting. What is fair to the donor in these situations?

HeLa cells have left their mark in history and continue to redefine our future both on ethical issues and medical victories. Henrietta Lacks never gave consent for the use of her cells and never saw any compensation, while millions were made from her body.

This begs the question, should her cells have been used without her consent, should she have been compensated, and should her family have received compensation from the profit that companies have made using these cells? These are all questions that are debated. So what about you, what do you think about the ethics of HeLa cells?
