Spotlight: Henrietta Lacks
Before modern ethical standards in biomedical research were codified, Henrietta Lacks became one of the most consequential figures in the history of cellular science, without ever knowing it.
Unfortunate beginnings
Henrietta Lacks was an African-American tobacco farmer and housewife from Maryland. In 1951, she was diagnosed with cervical cancer and treated at Johns Hopkins Hospital in Baltimore. During an examination by researcher George Otto Gey, cells were taken from her tumour without her knowledge or consent.
Those cells turned out to be remarkable. Unlike most human cells at the time, they survived and reproduced outside the body indefinitely. Designated "HeLa" cells (after Henrietta Lacks), they were distributed, commercialised, and genetically modified throughout scientific communities worldwide. For decades, the Lacks family knew nothing. It was not until 1975 that they learned Henrietta's cells were still alive in laboratories across the globe.
The ethical weight of the case
The case has become a foundational reference point in research ethics. It illustrates the consequences of collecting biological material without informed consent, and the complications that arise when that material becomes commercially valuable.
In 1990, the California Supreme Court ruled, in the landmark case Moore v. Regents of the University of California, that patients do not retain ownership rights over discarded biological tissue. But the situation became far more complex with the advent of genetic sequencing. In March 2013, researchers published the full HeLa genome without any consultation with the Lacks family, at a point when genomic data could reveal sensitive inherited information not just about Henrietta but about her living descendants too. The backlash led, later that same year, to the NIH negotiating a formal data access agreement with the family: a six-person review panel, including two Lacks family representatives, now controls access to HeLa whole genome data, requiring researchers to disclose commercial plans and acknowledge the family in any resulting publications.
A legacy worth naming
The scientific contributions of HeLa cells are extraordinary. They have been used in developing the polio vaccine, cancer research, HIV/AIDS research, COVID-19 vaccine development, and countless other advances, with some estimates crediting the cell line with contributing to research that has saved millions of lives. Speaking at a 2021 WHO event honouring Henrietta Lacks, the organisation's then Chief Scientist Soumya Swaminathan put the scale of that contribution plainly:
"I cannot think of any other single cell line or lab reagent that's been used to this extent and has resulted in so many advances." Dr Soumya Swaminathan, WHO Chief Scientist, at the Henrietta Lacks Director-General's Award ceremony, 2021
A timeline of recognition, decades late
| Year | What happened |
|---|---|
| 1951 | Cells taken from Henrietta Lacks's tumour without consent; she dies of cervical cancer the same year |
| 1975 | The Lacks family learns, by chance, that her cells are still alive in laboratories worldwide |
| 1990 | Moore v. Regents establishes that patients have no ownership rights over discarded tissue |
| 2013 | HeLa genome published without family consultation; NIH negotiates a data access agreement with the family later that year |
| 2021 | WHO honours Henrietta Lacks with a Director-General's Award, presented to her son Lawrence Lacks |
| 2021 to 2023 | The Lacks estate sues Thermo Fisher Scientific for unjust enrichment over continued commercial use of HeLa cells; the parties settle confidentially in August 2023 |
That gap between 1951 and any form of acknowledgement or compensation, more than seventy years, is itself part of the lesson. Recognition and legal reckoning arrived only after sustained pressure from the family, not as a natural consequence of the science succeeding.
Henrietta Lacks was inducted into the National Women's Hall of Fame. Astronomical bodies have been named in her honour. Her epitaph reads: "Her immortal cells will continue to help mankind forever."
The standards that now protect research participants, informed consent chief among them, exist in part because of what happened to her. That is a complicated tribute, but an important one to acknowledge, and the 2023 settlement suggests the story is still being resolved rather than safely confined to history.
For anyone working in research today, the practical lesson sits alongside the historical one. Consent isn't a single form signed at the start of a study. Henrietta Lacks never consented to her cells being taken in 1951, and her descendants were never asked before their family's genetic information was published in 2013, more than six decades later. Biological material and the data derived from it can outlive the original interaction with a participant by generations, which is exactly why modern consent frameworks increasingly ask what happens to samples and data long after a study formally ends, not just what happens during it.
