Henrietta Lacks and HeLa Cells: Science, Ethics, and Legacy

The Legacy of Henrietta Lacks: A Story of Science, Ethics, and Impact

Henrietta Lacks, an African American tobacco farmer and mother of five, unknowingly changed the future of science when her cancer cells were taken without her knowledge at Johns Hopkins Hospital in 1951. These cells, known today as HeLa cells, became the first immortal human cell line and have been central to countless medical breakthroughs. Yet, the story of Henrietta Lacks is also one about race, informed consent, and the ongoing impact of her legacy on her family and society at large.

Who Was Henrietta Lacks?

Born on August 18, 1920, in rural Virginia, Henrietta Lacks lived most of her life as a tobacco farmer. She was married to David Lacks and together they raised five children. In early 1951, Henrietta began experiencing unusual pain and bleeding. She soon discovered a lump, which led her to seek treatment at Johns Hopkins Hospital, one of the few medical facilities at the time that provided care for Black patients in segregated Baltimore.

• Date of birth: August 18, 1920
• Place of birth: Roanoke, Virginia
• Occupation: Tobacco farmer, mother of five
• Date of death: October 4, 1951, at age 31

The Medical Context: Johns Hopkins and 1950s Research Culture

During the 1950s, Johns Hopkins was at the forefront of cancer research. Dr. Richard TeLinde, head of Gynecology, and Dr. George Gey, who led tissue culture research, were exploring whether cancer cells could be grown outside the human body to better understand cancer and test treatments. At the time, it was standard practice to take tissue samples from patients—in particular, poor and minority patients—without their consent or compensation, especially if they received free care in public wards.

• Use of patient tissues for research without consent was common.
• Racial and social inequities influenced research practices.
• The notion of ‘payment’ for medical care through participation in research was prevalent.

Henrietta’s Diagnosis and Treatment

In February 1951, Henrietta was diagnosed with stage I cervical cancer. During her initial biopsy, physicians removed two tissue samples from her cervix—one cancerous, one healthy—without informing Henrietta. These samples were sent to Dr. Gey’s lab for cell culture experiments. Henrietta underwent the standard treatment of the era: radiation therapy, specifically by placing radium tubes on her cervix in multiple sessions. Despite enduring pain and aggressive treatments, her cancer rapidly progressed.

Henrietta’s stay at Johns Hopkins unfolded under pressing circumstances:

• February 1951: Biopsy and diagnosis
• Subsequent months: Hospitalization and radiation treatments
• August 1951: Re-admitted for escalating pain; cancer had metastasized
• October 4, 1951: Passed away at age 31

The Discovery: HeLa—The Immortal Cell Line

Dr. George Gey’s team noticed something extraordinary about the cancer cells taken from Henrietta’s tumor: unlike all previous samples, which died within days, these cells not only survived, but flourished. They could be divided and grown indefinitely in the lab without dying out—earning them the moniker ‘immortal.’ The new cell line was named HeLa, using the first two letters of Henrietta’s first and last name as a form of anonymization.

• HeLa cells: First human cells to be successfully cultured and grown indefinitely in vitro.
• HeLa cells multiplied rapidly, allowing for extensive research and distribution.
• These cells helped pioneer tissue culture technique and cell biology.

The sheer volume of HeLa cells produced is staggering—estimates suggest that all HeLa cells grown collectively would weigh over 50 million metric tons.

Impact on Science and Medicine

HeLa cells have become the most widely used human cell line in biomedical research. Their role in scientific discovery is unparalleled:

• Polio Vaccine: Enabled testing and mass production of the first effective polio vaccine.
• Cancer Research: Used to better understand cancer’s growth, metastasis, and potential treatments.
• Virology & Vaccines: Helped in developing vaccines for human papillomavirus (HPV) and advancing AIDS research.
• Genetics: Crucial for gene mapping and identifying mechanisms of cellular aging and division.
• Space Research: Sent into space to observe the impact of zero gravity on human cells.

HeLa cells transformed the landscape of medicine by becoming a standard laboratory tool, enabling researchers worldwide to conduct experiments previously thought impossible.

Ethical Issues: Consent, Compensation, and Race

The story of Henrietta Lacks is also a watershed moment in medical ethics. Her cells were taken without her consent, at a time when disclosure or compensation for such procedures was virtually nonexistent—especially for poor and Black patients.

• No informed consent was sought from Henrietta or her family for the use of her tissues.
• The Lacks family was unaware of HeLa cells’ existence for more than two decades.
• HeLa cells led to commercial gain and significant scientific prestige, while the Lacks family did not see financial benefits and long struggled to access adequate healthcare.
• The case highlights enduring concerns about medical experimentation on marginalized communities.

The Lacks Family: Discovery and Advocacy

For more than two decades, the Lacks family remained unaware that their mother’s cells had become world famous. The truth began to emerge in the 1970s, when scientists, journalists, and, eventually, the public connected HeLa to Henrietta Lacks.

• 1976: Rolling Stone article spotlighted connections between HeLa cells and the Lacks family.
• The family was bewildered by the concept of Henrietta’s cells living on in research labs across the globe, having never consented to or benefited from these developments.
• Confusion, anger, and a struggle for recognition fueled advocacy from Henrietta’s descendants.
• Prominent works—most notably, Rebecca Skloot’s 2010 book The Immortal Life of Henrietta Lacks—brought national attention to their story.

HeLa’s Transformative Role in Medicine

HeLa cells have enabled several of the most significant advances in modern medicine. They remain foundational for contemporary research:

• Testing new cancer drugs and therapies
• Advanced understanding of viruses, genetics, and cell function
• Vaccine development for critical diseases
• Study of the effects of radiation and toxins on humans
• Research into cloning, gene mapping, and in vitro fertilization

HeLa cells are credited with contributing to over 70,000 scientific papers and thousands of medical patents, making them arguably the most important biological tool of the last century.

Recognition, Memorialization, and Continuing Impact

For decades after her death, neither Henrietta Lacks nor her family received public acknowledgement. This changed slowly as awareness grew about the invaluable contributions—and the injustices—of her story:

• Honors and Memorials: Henrietta Lacks is recognized worldwide in educational materials, research facilities are named in her honor, and statues have been erected commemorating her contributions.
• Documentaries and Books: The 2010 book The Immortal Life of Henrietta Lacks brought her story into popular culture, followed by a critically acclaimed HBO film.
• Ethics Legislation: The story of HeLa cells helped catalyze changes in laws regarding informed consent and tissue research, including the Common Rule (revised in 2018) in the U.S.

Continuing Questions: Equity, Consent, and Access

The journey of HeLa cells continues to prompt vital debate and reflection:

• What rights do individuals and families have over tissues or genetic materials after they’re removed from the body?
• How should researchers share credit and benefits for discoveries made with donated tissues?
• What obligations do medical institutions, especially those with histories of unjust practices, have toward the communities involved?
