The cell line grew from a sample of cervical cancer cells taken from an African-American woman named Henrietta Lacks on February 8, He described the whole experience with them as "powerful", saying that it brought together "science, scientific history and ethical concerns" in a unique way.
Her cancer cells have continued to live well beyond her death in labs around the world, replicating so prolifically that laid end-to-end they could be wrapped around the earth three times. And to this day, HeLa cells have saved countless lives, and many scientific landmarks such as cloning, gene mapping, in vitro fertilization, the polio vaccine… have used HeLa cells and owe everything to the life and death of Henrietta Lacks.
InTheodore Puck and Philip Marcus cloned HeLa the first human cells to be cloned and freely donated samples to other researchers. Some 70, studies have been published involving the use of HeLa cells and they are in widespread use throughout the field of immunology.

Scientists don't routinely test the purity of their cell lines, so HeLa had contaminated many in vitro lines estimated 10 to 20 percent before the problem was identified.
