There are many strains of HeLa cells, because they mutate during division in cell cultures, but all HeLa cells are descended from the same tumor cells removed from Lacks.
This analysis further highlights the persistent impact of HeLa cells in science and medicine, proving that they have been a consistent, essential tool that has allowed researchers to expand the knowledge base in fields such as cancer biology, infectious disease, and many others.
HeLa cells could be produced in enormous quantities cheaply and quickly, making mass testing possible. The polio vaccine was declared safe and effective in 1955, and HeLa cells played a direct role in getting it there.
The Importance of HeLa Cells Among the important scientific discoveries of the last century was the first immortal human cell line known as “HeLa” — a remarkably durable and prolific line of cells obtained during the treatment of Henrietta’s cancer by Johns Hopkins researcher Dr. George Gey in 1951.
HeLa cells are the first immortal human cells to be grown in culture and the basis for countless significant scientific discoveries. They were isolated in 1951 from a cervical carcinoma derived from a 31-year-old patient.
HeLa cells were the first human cell line to be established and have been widely used in laboratory studies, especially in research on viruses, cancer, and human genetics.

HeLa cells represent a unique and enduring line of human cells that have profoundly shaped biomedical research. They are recognized as the first human cells capable of continuous growth and division in a laboratory setting.
