(Gey had cultured other species and had worked for over 20 years with this aim) Cancer researchers considered cultured human cells to hold the key to discovering a cure Provided a model cell line for studying normal cellular processes as well as many diseases

- 17. HeLa cells By 1954,the HeLa strain of cells was being used by Jonas Salk to develop a vaccine for polio. To test Salk's new vaccine, the cells were quickly put into mass production in the first-ever cell production factory.
- 18. Enormous number ofuses for her cells Research into cancer, AIDS, the effects of radiation and toxic substances, gene mapping, in vitro fertililsation and countless other scientific pursuits". Test human sensitivity to tape, glue, cosmetics, and many other products. Scientists have grown some 20 tons of her cells, and there are almost 11,000 patents involving HeLa cells. The cells have been used in 74,000 studies.
- 19. HeLa cells inspace Research into the effect space has on cells and tissues was also carried out using HeLa cells. Henrietta’s cells were were on board of the satellite Korabl- Sputnik 2 in 1960. They were also on board the first manned space flight in1961
- 20. Her family laterlearnt about these cells In the early 1970s, the family of Henrietta Lacks started getting calls from researchers who wanted blood samples from them to learn the family's genetics (eye colours, hair colours, and genetic connections). The family questioned this, which led to them learning about the removal of Henrietta's cells. Henrietta’s cells had been bought and sold by the billions, yet she remained virtually unknown while her family were too poor to afford health insurance.

In 1990 in America, the court ruled that a person's discarded tissue and cells are not their property and can be commercialized. n March 2013, German researchers published the DNA code, or genome, of a strain of HeLa cells http://www.huffingtonpost.com/2013/08/07/henrietta- lacks-family-settlement-on-dna-info_n_3720936.html
- 24. A highly recommendedread! Recognition then followed. The Immortal Life of Henrietta Lacks, by Rebecca Skloot is a superb book which documents the histories of both the HeLa cell line and the Lacks family. It tells a riveting story of the collision between ethics, race, and medicine; of scientific discovery and faith healing; and of a daughter consumed with questions about the mother she never knew. It’s a story inextricably connected to the dark history of experimentation on African Americans, the birth of bioethics, and the legal battles over whether we control the stuff we’re made of.
