Few names in the medical history have had a profound impact like Henrietta Lacks’s. Her story combines scientific breakthroughs, ethics and the indomitability of spirit. The cell line known as HeLa, which was derived from her cells, revolutionized medicine and to this day it is responsible for some scientific advances that we see today. Nevertheless, the story about Henrietta Lacks is also much about ethics and human dignity than anything else about science.

Henrietta Lacks: A Life Interrupted

She was born on August 1st, 1920 in Roanoke, Virginia as Loretta Pleasant. Her mother died during birth and she was raised by her grandfather at Clover, Virginia. It wasn’t easy considering life on a tobacco farm but Henry’s strength did not waver at all. She left for Turner Station, Maryland with David Lacks her husband in 1941 aiming to improve their lives during World War II.

In January 1951 she went to Johns Hopkins Hospital in Baltimore after experiencing severe abdominal pain and abnormal bleeding since it was the only hospital available around that treated black patients. Dr Howard Jones diagnosed a very aggressive form of cervical cancer with her illness advancing so quickly even though she had been subjected to radiation therapy.

The Unintended Contribution

Unknown to her then or consented to by her tumor cells were taken while she underwent treatment as usual during those days. Dr George Gey who was a renowned researcher on cancer wanted to develop human cells that could survive outside the body. However, what characterized Henrietta’s cells was that they were able to keep dividing indefinitely thereby becoming the first immortal human cell line ever discovered.

This HeLa line got its name from Gey using letters H-E-L-A drawn from both Henrietta’s first name and surname initial two letters respectively. They were highly replicative cells being freely distributed across labs worldwide hence acting as stepping stones towards various scientific advancements.

Scientific Milestones Enabled by HeLa Cells

The rapid replication of HeLa cells made them an unprecedented resource for researchers.

Here are some of the key milestones in medical science that trace their origins back to them:

  1. Development of the Polio Vaccine: In the 1950s, Jonas Salk used HeLa cells to test his first polio vaccine leading to its widespread use and eventual eradication of polio from many parts of the world.
  2. Cancer Research: In oncology, HeLa cells have contributed significantly by enabling cancerous cell actions, genetics, and response towards medication study.
  3. Virology: Understanding viral infections such as those caused by HIV and development of vaccines for diseases like measles and mumps was influenced greatly by these cells.
  4. Genetics: This is because they were utilized in determining human genes as well as studying how chromosomes behave thus aiding in mapping out human genome project.
  5. Space Research: The effects of zero gravity on human cells were studied using NASA’s samples of HeLa cells thereby making a contribution towards space biology.

Ethical Implications and Controversies

There are serious ethical issues related to this matter which include:

  1. Informed Consent: Henrietta was never told nor asked permission to take her cells resulting in discussions about patients’ rights and informed consent.
  2. Privacy and Ownership: In 1970s it became known that there existed such thing as “HeLa” for Lacks family who did not get any acknowledgement or payment despite having significant gains from their use.
  3. Racial And Social Inequities: It points out exploitation black population experienced during clinical research based on cases such as Henrietta’s revealing racial disparities during those times.

The Lacks Family’s Journey

It was in the 1970s that the Lacks family made a discovery of the HeLa cells which led to a protracted struggle for recognition and justice. Rebecca Skloot’s book, “The Immortal Life of Henrietta Lacks,” which appeared in 2010 made their story known to many. The publication exposed some of Henrietta’s contributions and brought forth a variety of ethical concerns surrounding her life thus urging individuals to look at other aspects concerning bioethics.

To honor Henrietta Lacks

Lately, Henrietta Lacks’ heritage has been increasingly acknowledged. The Lacks family created the Henrietta Lacks Foundation for offering financial assistance to people who have engaged into scientific research without any personal gain. Memorials have been set up by institutions such as Johns Hopkins and scholarships established in her name.


Henrietta lacks’ narrative is an inspiring account of scientific victory as well as moral rousing. Notably, it is through HeLa cell line that many lives have been saved including furthering developments in medical science. However, even as we continue to enjoy from her cells, it remains vital that we respect Henrietta lacks’ legacy so that her tale will be foundation upon which ethical principles in medical investigations are based.

The contribution she made as a person shows how a single life can impact on the globe. Her undying cells remind humanity about ethical practices and human stories behind every scientific advancement.
