HeLa cells are rapidly dividing cancer cells, and the number of chromosomes varies during cancer formation and cell culture. The current estimate (excluding very tiny fragments) is a "hypertriploid chromosome number (3n+)", which means 76 to 80 total chromosomes (rather than the normal diploid number of 46) with 22–25 clonally abnormal ...

African-American woman (1920–1951), source of HeLa immortal cell line "Lacks" redirects here. For other uses, see Lack. Henrietta Lacks Lacks c. 1945–1951.

Due to the unusual growth capabilities of the HeLa cell line, it also contaminated many cell cultures and ruined years of research, as discovered by Stanley Gartler in 1966. [3] The cells, as it turned out, could float on dust particles and could be transferred on unwashed hands or used pipettes, and therefore end up in other cell cultures. [6]
On Aug. 1, 2023, over 70 years after doctors took Lacks’ cells without her consent or knowledge, her family reached a settlement with biotech company Thermo Fisher. Lacks’ What are HeLa cells?
Researchers who studied this sample found that her cells kept reproducing, ultimately making them immortal. Lacks died in 1951, but to this day her cells – known as “HeLa” cells – continue ...
One reviewer for The New Atlantis, while mostly positive about the book, questioned its ethical arguments about tissue markets and informed consent involving scientists such as Chester M. Southam, and claimed to have found factual errors: one related to the role of HeLa cells in early space missions, and, another related to a statement in the ...
Henrietta Lacks’ unique ‘Hela’ cells played a crucial role in the development of Covid-19 vaccines and treatments for HIV, leukemia and cancer
Walter Nelson-Rees (January 11, 1929 – January 23, 2009) was a cell culture worker and cytogeneticist who helped expose the problem of cross-contamination of cell lines. He used chromosome banding to show that many immortal cell lines , previously thought to be unique, were actually HeLa cell lines .
