Henrietta Lacks's cells become HeLa
In 1951, surgeon Howard Jones took a biopsy of Henrietta Lacks's cervical tumor at Johns Hopkins, a public-ward hospital that treated poor Black patients. Researcher George Gey found that her cells, unlike any before them, kept dividing indefinitely in culture. The HeLa line was then used to develop the polio vaccine and to advance gene mapping and cancer research, while Lacks died at 31 and her family learned of the cells only in the 1970s, still unable to afford health insurance.
