Henrietta Lacks was born on August 1, 1920, in Roanoke, Virginia. Lacks died of cervical cancer on October 4, 1951, at age 31. Cells taken from her body without her knowledge were used to form the HeLa cell line, which has been used extensively in medical research since that time. Lacks's case has sparked legal and ethical debates over the rights of an individual to his or her genetic material and tissue.
Henrietta Lacks was born Loretta Pleasant on August 1, 1920, in Roanoke, Virginia. At some point, she changed her name to Henrietta. After the death of her mother in 1924, Henrietta was sent to live with her grandfather in a log cabin that had been the slave quarters of a white ancestor's plantation. Henrietta Lacks shared a room with her first cousin, David "Day" Lacks. In 1935, the cousins had a son they called Lawrence. Henrietta was 14. The couple had a daughter, Elsie, in 1939, and married in 1941.
Henrietta and David moved to Maryland at the urging of another cousin, Fred Garret. There, they had three more children: David Jr., Deborah and Joseph. They placed their daughter Elsie, who was developmentally disabled, in the Hospital for the Negro Insane.
On January 29, 1951, Lacks went to Johns Hopkins Hospital to diagnose abnormal pain and bleeding in her abdomen. Physician Howard Jones quickly diagnosed her with cervical cancer. During her subsequent radiation treatments, doctors removed two cervical samples from Lacks without her knowledge. She died at Johns Hopkins on October 4, 1951, at the age of 31.
The cells from Lacks's tumor made their way to the laboratory of researcher Dr. George Otto Gey. Gey noticed an unusual quality in the cells. Unlike most cells, which survived only a few days, Lacks's cells were far more durable. Gey isolated and multiplied a specific cell, creating a cell line. He dubbed the resulting sample HeLa, derived from the name Henrietta Lacks.
The HeLa strain revolutionized medical research. Jonas Salk used the HeLa strain develop the polio vaccine, sparking mass interest in the cells. Scientists cloned the cells in 1955, as demand grew. Since that time, over ten thousand patents involving HeLa cells have been registered. Researchers have used the cells to study disease and to test human sensitivity to new products and substances.
The Lacks family learned about the HeLa cells in the 1970s. In 1973, a scientist contacted family members, seeking blood samples and other genetic materials. Inquiries from the family regarding the use of HeLa cells, and publications that included their own genetic information, were largely ignored. The case gained new visibility in 1998, when the BBC screened an award-winning documentary on Lacks and HeLa. Rebecca Skloot later wrote a popular book on the subject, called The Immortal Life of Henrietta Lacks. Oprah Winfrey announced plans to develop a film based on Skloot's 2010 book.
Organizations that have profited from HeLa have since publicly recognized Henrietta Lacks's contributions to research.
