Jun 2, 2022 · As a cancer researcher who uses HeLa cells in my everyday work, even I sometimes find it hard to believe. Lacks' cervical cancer cells, called "HeLa" after the first two letters of her first and last name, are immortal, continuing to divide when most cells would die. This ability to survive through endless generations of cells is what makes ...

Normally, human cell cultures die within a few days after a set number of cell divisions via a process called senescence. This presents a problem for researchers because experiments using normal cells cannot be repeated on identical cells (clones), nor can the same cells be used for extended study. Cell biologist George Otto Gey took one cell from ...
HeLa cells have been used to test the effects of radiation, cosmetics, toxins, and other chemicals on human cells. They have been instrumental in gene mapping and studying human diseases, especially cancer. However, the most significant application of HeLa cells may have been in the development of the first polio vaccine. HeLa cells were used to ma...
While the HeLa cell line has led to amazing scientific breakthroughs, the cells can also cause problems. The most significant issue with HeLa cells is how aggressively they can contaminate other cell cultures in a laboratory. Scientists don't routinely test the purity of their cell lines, so HeLa had contaminated many in vitrolines (estimated 10 to...
The birth of the new field of biotechnology introduced ethical considerations. Some modern laws and policies arose from ongoing issues surrounding HeLa cells. As was the norm at the time, Henrietta Lacks was not informed her cancer cells were going to be used for research. Years after the HeLa line had become popular, scientists took samples from o...

70 years ago, Henrietta Lacks was treated for cervical cancer at Johns Hopkins Hospital in Baltimore, Maryland. She died mere months later but tumour cells taken from her went on to become the first immortal human cell line. The research breakthroughs this enabled cannot be overstated: 110,000 papers, 11,000 patents and 3 Nobel prizes are just ...
Sep 16, 2024 · HeLa cells are classed as immortal as they can divide multiple times without dying. This ability comes from the cells possessing an overactive version of the enzyme telomerase, which prevents the shortening of the chromosome telomeres, and so prevents cellular aging and cell death.
May 15, 2021 · Definition. HeLa cells, named after their original donor Henrietta Lacks, represent the most widely-used human cell line in the field of biological research. The cervical cells of a dying woman were kept alive (without consent) as ‘immortal’ cells in 1951 and fueled research into polio vaccination and isolation of the human immunodeficiency ...
Oct 8, 2020 · HeLa became the go-to human cells in biomedical research, and quickly made their way to labs all over the world. Henrietta’s cells fuelled a boom in biomedical research. They were instrumental in early genetic research too. They taught us about how diseases worked, including cancer, polio, HPV, HIV, herpes, mumps, measles, Zika, and many more.
