Henrietta Lacks

American woman whose cancer cells are the source of the HeLa cell line (1920–1951)

Tumor cells harvested from Henrietta Lacks during a cervical cancer biopsy in 1951 became the HeLa cell line, an immortalized biological specimen that continues to facilitate medical breakthroughs worldwide. Her involuntary contribution occurred at Johns Hopkins Hospital in Baltimore, where researchers utilized her biological samples without consent for scientific cultivation, fundamentally altering the landscape of modern biomedical research and cellular ethics.

Early Life in Virginia

Born Loretta Pleasant in 1920 in Roanoke, Virginia, she was later known as Henrietta Lacks. Following her mother's death in 1924, she moved to Clover, Virginia, where she was raised by her grandfather in a cabin formerly serving as slave quarters. She worked as a tobacco farmer from an early age, attending school until the sixth grade. By age 14, she gave birth to her first child, Lawrence, followed by a daughter, Elsie, in 1939.

Relocation to Maryland

After marrying David Lacks in 1941, the family moved to Turner Station, Maryland, to pursue employment at Bethlehem Steel. Lacks balanced her duties as a homemaker with raising five children. In November 1950, she gave birth to her final child at Johns Hopkins Hospital, only months before presenting to the same facility with symptoms of a cervical malignancy.

Medical Diagnosis and HeLa

In January 1951, Lacks received a diagnosis of epidermoid carcinoma of the cervix from Dr. Howard W. Jones. During her radium treatment, researchers extracted both healthy and cancerous tissue samples without her knowledge. These cells were provided to physician George Otto Gey, who successfully cultured the line into the immortal HeLa strain. Though she was later reclassified as having an adenocarcinoma, her treatment trajectory remained unchanged.

Final Months and Legacy

Lacks returned to Johns Hopkins in August 1951 due to severe abdominal pain and remained until her death on October 4, 1951, at age 31. An autopsy revealed that the cancer had metastasized systemically. She was interred in an unmarked grave in Clover, Virginia. Recognition arrived decades later, including her 2014 induction into the Maryland Women's Hall of Fame and the 2010 placement of a headstone at her burial site.

Fast facts

Questions readers ask

Was Henrietta Lacks aware that her cells were being used for research?

No. The samples were collected during her medical treatment in 1951 without her knowledge or informed consent.

What makes the HeLa cell line significant?

The HeLa cell line is the first immortalized human cell line, meaning it can reproduce indefinitely under specific laboratory conditions.

Did Lacks's family receive compensation for her cells?

No. Neither Lacks nor her family were compensated for the extraction or commercial use of her cell line.
